Summary
The Gemara discusses what other protective materials a bird could fall upon that would successfully cushion its impact and prevent it from being rendered a treifa. Relatedly, if a bird’s wings become stuck to each other or to its body, a debate arises as to whether or not the bird will become a treifa upon falling, as its ability to break the fall is compromised. Two opinions are brought regarding the scope of this debate – specifically, whether the dispute applies to a case where only one wing is glued or if it is restricted to a case where both wings are glued.
The Mishna rules that if the majority of an animal’s ribs are broken, it is a treifa. While there are twenty-six ribs total, consisting of thirteen on each side, two of these are excluded from the halakhic count; therefore, a majority is defined as twelve ribs, which can be comprised of six on each side or any other combination totaling twelve. Rav rules that even a single rib dislocated along with its socket from the vertebra renders the animal a treifa. Rav Asi and Rav Kahana then questioned Rav regarding a case where two opposite ribs are completely removed while the vertebra remains intact, to which Rav responded that it is a neveila because the animal is essentially cut in half. Several questions are raised against this response in light of Rav’s own previous statement, wondering why they would ask about two ribs if Rav already held that even one dislocated rib is a treifa. Ultimately, the Gemara resolves this by reinterpreting the precise details of their question and explaining that they were unaware of Rav’s original ruling when they questioned him.
Three of the seven extra cases of treifot introduced by the Amoraim were authored by Shmuel and are analyzed here because one of them directly relates to uprooted ribs.
The next case in the Mishna transitions to an attack by a predator animal that emits venom (derisa), creating a treifa status. At first, a statement of Rav is brought asserting that a cat does not emit venom capable of making an animal a treifa, prompting the Gemara to question why this rule could not be inferred directly from the wording of the Mishna itself. Rav Chisda rules that a cat and a mongoose do emit venom that can kill a small kid or a baby lamb. A contradictory braita is brought against this view, and the contradiction is ultimately resolved in two possible manners.

חוֹל הַדַּק – לָא חָיְישִׁינַן; חוֹל הַגַּס – חָיְישִׁינַן; אֲבַק דְּרָכִים – חָיְישִׁינַן; תִּיבְנָא וַעֲבִיד בִּזְגָּא – חָיְישִׁינַן; לָא עָבֵיד בִּזְגָּא – לָא חָיְישִׁינַן.
If the bird fell on fine sand, we need not be concerned, because the sand slides on impact, cushioning the fall. If it fell on coarse sand, we must be concerned, because there are large stones mixed into it. If it fell on dust of the road, we must be concerned, because the dust is compact and hard. If the bird fell on bundled straw, we must be concerned, because it is compact and hard. If the straw was not bundled, we need not be concerned.
חִיטֵּי וְכֹל דְּמִינַיְיהוּ – חָיְישִׁינַן; שְׂעָרֵי וְכֹל דְּמִינַיְיהוּ – חָיְישִׁינַן; כׇּל מִינֵי קִטְנִיּוֹת – אֵין בָּהֶם מִשּׁוּם רִיסּוּקֵי אֵבָרִים, לְבַר מִן רוּבְּיָא. חִימְצֵי – אֵין בּוֹ מִשּׁוּם רִיסּוּק אֵבָרִים, חִפְצֵי – יֵשׁ בּוֹ מִשּׁוּם רִיסּוּק אֵבָרִים. כְּלָלָא דְּמִלְּתָא: כֹּל מִידֵּי דְּמַשְׁרֵיק – אֵין בּוֹ מִשּׁוּם רִיסּוּק אֵבָרִים, לָא מַשְׁרֵיק – יֵשׁ בּוֹ מִשּׁוּם רִיסּוּק אֵבָרִים.
If the bird fell on wheat and all similar types of grain, such as spelt or rye, whose kernels are hard, we must be concerned. If it fell on barley and all similar types of grain, such as oats, we must be concerned. With regard to all types of beans, there is no concern due to possible shattered limbs if a bird fell on them, since their round shape causes the bird to slide when it hits them, except for fenugreek. With regard to peas, there is no concern due to possible shattered limbs, but with regard to chickpeas, there is a concern due to possible shattered limbs. The principle of the matter is: With regard to anything that slips to the sides on impact, there is no concern due to possible shattered limbs. And with regard to anything that does not slip, there is a concern due to possible shattered limbs.
דָּבוֹק – רַב אָשֵׁי שָׁרֵי, אַמֵּימָר אָסַר. בְּחַד גַּפָּא – דְּכוּלֵּי עָלְמָא לָא פְּלִיגִי דִּשְׁרֵי, כִּי פְּלִיגִי בִּתְרֵי גַּפֵּי. מַאן דְּאָסַר אָמַר לָךְ: הֵיכִי נֵיקוּם? וּמַאן דְּשָׁרֵי אָמַר לָךְ: אֶפְשָׁר דְּנֵיקוּם אַעִיקְבֵי דְּגַפֵּי.
If the bird’s wings became stuck to a davuk, a board covered with glue set as a trap, and in trying to escape it fell to the ground while stuck to the board, Rav Ashi deemed the bird permitted, while Ameimar deemed it prohibited. The Gemara explains: In a case where only one wing was stuck to the board, everyone agrees that it is permitted, because the bird flaps with the other wing, lessening the impact of the fall. They disagree when both wings are stuck to the board. The one who deemed it prohibited could have said to you: How will it stand itself up so that it might dampen the impact? And the one who deemed it permitted could have said to you: It is possible for it to stand itself up by using the tips of its wings.
וְאִיכָּא דְּאָמְרִי: בִּתְרֵי גַּפֵּי כּוּלֵּי עָלְמָא לָא פְּלִיגִי דַּאֲסִיר, כִּי פְּלִיגִי בְּחַד גַּפָּא. מַאן דְּשָׁרֵי אָמַר לָךְ: אֶפְשָׁר דְּפָרַח בְּחַד גַּפָּא, וּמַאן דְּאָסַר: כֵּיוָן דִּבְהַאי לָא מָצֵי פָּרַח, בְּהַאי נָמֵי לָא מָצֵי פָּרַח. וְהִילְכְתָא: בִּתְרֵי גַּפֵּי אֲסִיר, בְּחַד גַּפָּא שְׁרֵי.
And there are those who say: In a case where two wings were stuck to the board, everyone agrees that it is prohibited, because it cannot dampen the impact. They disagree when only one wing is stuck to the board. The one who deemed it permitted could have said to you: It is possible for it to fly with one wing and dampen the fall. And the one who deemed it prohibited could say: Since it cannot fly with this wing that is stuck to the davuk, it also cannot fly with that untrapped wing. The Gemara concludes: And the halakha is: In a case where two wings were stuck, it is prohibited. In a case where only one wing was stuck, it is permitted.
נִשְׁתַּבְּרוּ רוֹב צַלְעוֹתֶיהָ. תָּנוּ רַבָּנַן: אֵלּוּ הֵן רוֹב צְלָעוֹת – שֵׁשׁ מִכָּאן וְשֵׁשׁ מִכָּאן, אוֹ אַחַת עֶשְׂרֵה מִכָּאן וְאַחַת מִכָּאן.
§ The mishna states that if most of an animal’s ribs were fractured, it is a tereifa. The Sages taught: These are most of the ribs: Six from here and six from there, i.e., six on each side, or eleven from here and one from there. Twenty-two ribs are significant for matters of tereifot, eleven on each side. Twelve fractured ribs constitutes a majority.
אָמַר זְעֵירִי: וּמֵחֶצְיָין כְּלַפֵּי שִׁדְרָה. אָמַר רַבָּה בַּר בַּר חָנָה אָמַר רַבִּי יוֹחָנָן: וּבִצְלָעוֹת גְּדוֹלוֹת שֶׁיֵּשׁ בָּהֶן מוֹחַ.
Ze’eiri says: And this applies only when the ribs were fractured from the half of the rib toward the spine, but not if they were fractured on the other half. Rabba bar bar Ḥana says that Rabbi Yoḥanan says: And this applies only to fractures occurring in large ribs that contain marrow; fractures in small ribs do not render the animal a tereifa.
אָמַר עוּלָּא, בֶּן זַכַּאי אָמַר: נֶעְקְרוּ – בְּרוֹב צַד אֶחָד, נִשְׁתַּבְּרוּ – בְּרוֹב שְׁנֵי צְדָדִין. רַבִּי יוֹחָנָן אָמַר: בֵּין נֶעְקְרוּ בֵּין נִשְׁתַּבְּרוּ – בְּרוֹב שְׁנֵי צְדָדִין.
§ Ulla said that ben Zakkai says: If the ribs were dislocated from the spine, even a majority of one side, i.e., six dislocated ribs, is enough to render the animal a tereifa. Only if the ribs were broken is a majority of both sides necessary. Rabbi Yoḥanan says: Whether they were dislocated or broken, the animal is a tereifa only with a majority of both sides.
אָמַר רַב: נֶעֶקְרָה צֵלָע וְחוּלְיָא עִמָּהּ – טְרֵפָה. אָמְרִי לֵיהּ רַב כָּהֲנָא וְרַב אַסִּי לְרַב: נֶעֶקְרָה צֵלָע מִכָּאן וְצֵלָע מִכָּאן, וְחוּלְיָא קַיֶּימֶת, מַהוּ? אֲמַר לְהוּ: גִּיסְטְרָא קָאָמְרִיתוּ?!
Rav says: If a rib was dislocated and the attached vertebra was torn out with it, the animal is a tereifa, even if the spinal cord remains intact. Rav Kahana and Rav Asi said to Rav: If a rib was dislocated from here and another rib from there, i.e., both ribs connected to a single vertebra were dislocated, but the vertebra itself remains intact, what is the halakha? Rav said to them: Are you saying that an animal that was sliced in half is a tereifa? This animal is considered to have been sliced and already has the status of a carcass, as it is already considered dead (see 21a).
וְהָא רַב נָמֵי גִּיסְטְרָא קָאָמַר? כִּי קָאָמַר רַב – צֵלָע בְּלֹא חוּלְיָא.
The Gemara asks: But didn’t Rav also say that a sliced animal is a tereifa, since he said that if a rib was dislocated along with the attached vertebra, the animal is a tereifa? In such a case, the opposite rib is inevitably detached. If so, the animal should be considered a carcass. The Gemara responds: When Rav said that such an animal is a tereifa, he was referring to a case where the rib was dislocated without the vertebra.
וְהָא צֵלָע וְחוּלְיָא קָאָמַר? צֵלָע וַחֲצִי חוּלְיָא.
The Gemara asks: But didn’t Rav explicitly say his statement with regard to a rib and vertebra that were dislocated? The Gemara responds: Rav meant that if a rib and half its attached vertebra were dislocated, the animal is a tereifa. The opposite rib, however, is intact and connected to the remainder of the vertebra.
מִכְּלָל דְּרַב כָּהֲנָא וְרַב אַסִּי, צֵלָע בְּלֹא חוּלְיָא אָמְרִי, וַאֲמַר לְהוּ: ״גִּיסְטְרָא קָאָמְרִיתוּ״? וְהָאָמַר עוּלָּא: בֶּן זַכַּאי אָמַר: נֶעְקְרוּ – בְּרוֹב צַד אֶחָד, נִשְׁתַּבְּרוּ – בְּרוֹב שְׁנֵי צְדָדִין.
The Gemara challenges: By inference, one may conclude that Rav Kahana and Rav Asi stated their question with regard to a less serious case, i.e., where a rib from each side was torn out without the vertebra being damaged at all. And yet, Rav said to them: Are you saying that an animal that was sliced in half is a tereifa? Rather, this animal is a carcass and is certainly prohibited. And how could Rav say this? But didn’t Ulla say that ben Zakkai says: If the ribs were dislocated, even a majority of one side is enough to render the animal a tereifa, while if the ribs were broken, a majority of both sides is necessary? If so, any animal with fewer than six dislocated ribs should be kosher, as long as the spine is undamaged.
אָמַר לָךְ: הָתָם זֶה שֶׁלֹּא כְּנֶגֶד זֶה, הָכָא זֶה כְּנֶגֶד זֶה.
The Gemara responds: Rav could have said to you: There, where ben Zakkai says that six dislocated ribs on one side render the animal a tereifa, this is referring only to ribs not dislocated one opposite the other. Here, where Rav says that two dislocated ribs render the animal a carcass, this is referring to ribs dislocated one opposite the other.
וְהָאָמַר רַבִּי יוֹחָנָן: בְּרוֹב שְׁנֵי צְדָדִין, וּבְרוֹב שְׁנֵי צְדָדִין אִי אֶפְשָׁר דְּלָא קָיְימָא (חד) [חֲדָא] מִינַּיְיהוּ זֶה כְּנֶגֶד זֶה!
The Gemara asks: But doesn’t Rabbi Yoḥanan say that the animal is a tereifa only if a majority of both sides was dislocated, and in a majority of both sides, it is impossible that one of them is not situated opposite another? Still, Rabbi Yoḥanan says that the animal is a tereifa and not a carcass.
הָתָם – בּוּכְנָא בְּלָא אֲסִיתָא, הָכָא – בּוּכְנָא וַאֲסִיתָא.
The Gemara responds: There, Rabbi Yoḥanan is referring to a case where the pestle, i.e., the end of the rib, was torn out without the mortar, the socket of the vertebra in which it sits, leaving the spine completely intact. In such a case, the animal is a tereifa only if twelve ribs were dislocated, even though this necessarily includes one rib opposite another. Here, where Rav says that two dislocated ribs opposite one another render the animal a carcass, that is referring to a case where the pestle and mortar were torn out together, damaging the spine.
אִי הָכִי, הַיְינוּ דְּרַב? לָא שְׁמִיעַ לְהוּ דְּרַב.
The Gemara asks: If so, why did Rav Kahana and Rav Asi ask anything of Rav? Their case in question is identical to the statement of Rav. If Rav says that the animal is a tereifa if a rib and part of its vertebra were dislocated, that should be the halakha all the more so if ribs opposite one another were dislocated in addition to part of the attached vertebra. The Gemara responds: Rav Kahana and Rav Asi did not hear that statement of Rav.
וְלִיבְעוֹ מִינֵּיהּ כִּדְרַב? סָבְרִי: לִיבְעֵי מִינֵּיהּ חֲדָא דְּפָרֵישׁ לַן תַּרְתֵּי, דְּאִי בָּעֵינַן מִינֵּיהּ חֲדָא, הָנִיחָא אִי אֲמַר לַן ״טְרֵפָה״ – כׇּל שֶׁכֵּן תַּרְתֵּי, אִי אֲמַר לַן ״כְּשֵׁרָה״ – אַכַּתִּי תַּרְתֵּי קָא מִיבַּעְיָא לַן.
The Gemara persists: But if so, let them ask about the simpler case of one dislocated rib, like that which Rav himself discussed. Why ask specifically about two ribs opposite one another? The Gemara responds: They reasoned: Let us ask him one question through which he will explain to us two different cases. As, if we ask him about only one dislocated rib, this works out well if he says to us that the animal is a tereifa, because we can infer that all the more so if two ribs opposite one another are dislocated, the animal is a tereifa. But if he says to us that it is kosher, we must still ask with regard to a case of two dislocated ribs.
אִי הָכִי, הַשְׁתָּא נָמֵי דְּקָא בָּעֵי מִינֵּיהּ תַּרְתֵּי, הָנִיחָא אִי אֲמַר לְהוּ ״כְּשֵׁרָה״ – כׇּל שֶׁכֵּן חֲדָא; וְאִי אֲמַר לְהוּ ״טְרֵפָה״, אַכַּתִּי חֲדָא מִיבַּעְיָא לְהוּ.
The Gemara objects: If that is so, then now, too, when they ask him about two ribs, they may not receive an answer with regard to both cases. Granted, this works out well if he says to them that an animal with two dislocated ribs opposite one another is kosher, since they can infer that all the more so it is kosher if only one rib is dislocated. But if he says to them that it is a tereifa, they must still ask with regard to a case of only one dislocated rib.
סָבְרִי: אִם כֵּן מִירְתָּח קָא רָתַח. חֲדָא טְרֵפָה, תַּרְתֵּי מִיבַּעְיָא?
The Gemara responds: They reasoned that it is better to ask about a case where two ribs opposite one another were dislocated, because if it is so that Rav holds that the animal is a tereifa if even one rib is dislocated, then he would become angry and respond: If an animal with even one dislocated rib is a tereifa, is it necessary to ask about an animal with two dislocated ribs?
וְהָא קָא אָמְרִי לֵיהּ וְלָא רָתַח, כֵּיוָן דְּקָאָמַר לְהוּ ״גִּיסְטְרָא קָאָמְרִיתוּ״ – הַיְינוּ רִיתְחֵיהּ.
The Gemara objects: But they did say this question to him and he did not become angry, despite the fact that he holds that even one dislocated rib renders the animal a tereifa. The Gemara responds: When he said to them: Are you saying that an animal that was sliced in half is a tereifa, this is his anger. Rav Kahana and Rav Asi understood from this response that an animal with two dislocated ribs opposite one another is a carcass, but an animal with one dislocated rib is a tereifa.
אָמַר רַבָּה בַּר רַב שֵׁילָא אָמַר רַב מַתְנָא אָמַר שְׁמוּאֵל: נֶעֶקְרָה צֵלָע מֵעִיקָּרָהּ, וְגוּלְגּוֹלֶת שֶׁנֶּחְבְּסָה בְּרוּבָּה, וּבָשָׂר הַחוֹפֶה אֶת רוֹב הַכָּרֵס בְּרוּבּוֹ – טְרֵפָה.
§ Rabba bar Rav Sheila says that Rav Mattana says that Shmuel says: If a rib was ripped from its root, or if the skull was crushed in its majority, or if the flesh that envelops the majority of the rumen was damaged in its majority, the animal is a tereifa.
נֶעֶקְרָה צֵלָע מֵעִיקָּרָהּ טְרֵפָה? וּרְמִינְהוּ:
The Gemara asks: Did Shmuel really say that if a rib was ripped from its root, the animal is a tereifa? But raise a contradiction from a mishna (Oholot 2:3):
כַּמָּה חִסָּרוֹן בְּשִׁדְרָה? בֵּית שַׁמַּאי אוֹמְרִים: שְׁתֵּי חוּלְיוֹת, וּבֵית הִלֵּל אוֹמְרִים: חוּלְיָא אַחַת, וְאָמַר רַב יְהוּדָה אָמַר שְׁמוּאֵל: וְכֵן לִטְרֵפָה.
How much is considered a deficiency in the spine of a corpse so that it will not be considered a full corpse that would render one impure in a tent? Beit Shammai say: Two missing vertebrae, and Beit Hillel say: One vertebra. And Rav Yehuda says that Shmuel says: And just as Beit Shammai and Beit Hillel disagree with regard to ritual impurity, so too they disagree with regard to a tereifa, i.e., according to Beit Hillel an animal missing only one vertebra is a tereifa. Evidently, Shmuel holds that a missing vertebra renders the animal a tereifa, but a dislocated rib does not.
הָכָא – צֵלָע בְּלֹא חוּלְיָא, הָתָם – חוּלְיָא בְּלֹא צֵלָע.
The Gemara responds: This is not difficult. Here, where Shmuel says that a rib ripped from its root renders the animal a tereifa, he is referring to a case where the rib was torn out without the vertebra. There, where he says that a missing vertebra renders the animal a tereifa according to Beit Hillel, he is referring to a case where the vertebra was missing without the rib being dislocated. But if the rib itself was ripped from its root, the animal is a tereifa.
בִּשְׁלָמָא צֵלָע בְּלֹא חוּלְיָא – מַשְׁכַּחַתְּ לַהּ, אֶלָּא חוּלְיָא בְּלֹא צֵלָע – הֵיכִי מַשְׁכַּחַתְּ לַהּ? בְּשִׁילְהֵי כַּפְלֵי.
The Gemara asks: Granted, with regard to a case where a rib was dislocated without the vertebra, you find this commonly. But how can you find a case of a missing vertebra without a dislocated rib? The Gemara responds: This can occur at the ends of the flanks, where there are vertebrae with no ribs attached to them.
מַתְקֵיף לַהּ רַב אוֹשַׁעְיָא: וְלִתְנְיַיהּ גַּבֵּי קוּלֵּי בֵּית שַׁמַּאי וְחוּמְרֵי בֵּית הִלֵּל? אֲמַר לֵיהּ רַב: כִּי אִיתְּשִׁיל – לְעִנְיַן טוּמְאָה אִיתְּשִׁיל, דְּהָווּ לְהוּ בֵּית שַׁמַּאי לְחוּמְרָא.
Shmuel said that just as Beit Shammai and Beit Hillel disagree with regard to ritual impurity, so too they disagree with regard to a tereifa. Rav Oshaya objects to this statement: But if that is so, then the opinion of Beit Hillel is the more stringent one, as they hold that even one missing vertebra renders the animal a tereifa. Accordingly, let the tanna teach this dispute along with the list of leniencies of Beit Shammai and stringencies of Beit Hillel in tractate Eduyyot. Rav said to him: When the question was asked, it was asked with regard to the ritual impurity of a corpse. That is the source of the dispute between Beit Hillel and Beit Shammai, and on that matter, Beit Shammai constitute the stringent opinion. The parallel disagreement with regard to tereifot is not mentioned explicitly in any mishna or baraita, and it was therefore omitted from the list in tractate Eduyyot.
וְגוּלְגּוֹלֶת שֶׁנֶּחְבְּסָה בְּרוּבָּהּ. בָּעֵי רַבִּי יִרְמְיָה: רוֹב גּוֹבְהָהּ, אוֹ רוֹב הֶיקֵּיפָהּ? תֵּיקוּ.
The Gemara returns to Shmuel’s statement: Or if the skull was crushed in its majority, the animal is a tereifa. Rabbi Yirmeya raises a dilemma: Is this referring to the majority of its height or the majority of its circumference? The Gemara responds: The dilemma shall stand unresolved.
וּבָשָׂר הַחוֹפֶה רוֹב הַכָּרֵס בְּרוּבּוֹ. בָּעֵי רַב אָשֵׁי: בְּרוֹב קָרוּעַ, אוֹ בְּרוֹב נָטוּל?
Shmuel also said: Or if the flesh that envelops the majority of the rumen was damaged in its majority, the animal is a tereifa. Rav Ashi raises a dilemma: Is this referring even to a case where the majority of the length of the flesh was torn? Or is it referring only to a case where the majority of the flesh was removed, but if it was torn along the majority of its length the animal remains kosher?
תִּפְשׁוֹט לֵיהּ מִדִּתְנַן: כָּרֵס הַפְּנִימִית שֶׁנִּיקְּבָה, אוֹ שֶׁנִּקְרַע רוֹב הַחִיצוֹנָה, וְאָמְרִי בְּמַעְרְבָא מִשְּׁמֵיהּ דְּרַבִּי יוֹסֵי בְּרַבִּי חֲנִינָא: כׇּל הַכָּרֵס כּוּלּוֹ זוֹ הִיא כָּרֵס הַפְּנִימִי, וְאֵי זֶהוּ כָּרֵס הַחִיצוֹנָה? בָּשָׂר הַחוֹפֶה אֶת רוֹב הַכָּרֵס.
The Gemara responds: Resolve the dilemma from that which we learned in the mishna: If the internal rumen was perforated or most of the external rumen was torn, the animal is a tereifa. And in the West, Eretz Yisrael, they said in the name of Rabbi Yosei, son of Rabbi Ḥanina: The entire rumen is the internal rumen. And if so, which is the external rumen? It is the flesh that envelops the majority of the rumen. Apparently, the animal is a tereifa even if the flesh is torn in its majority.
מִידֵּי הוּא טַעְמָא, אֶלָּא לִשְׁמוּאֵל, הָכִי אָמַר רַבִּי יַעֲקֹב בַּר נַחְמָנִי אָמַר שְׁמוּאֵל: מָקוֹם שֶׁאֵין בּוֹ מֵילָת.
The Gemara rejects the proof: This explanation is meant only to clarify the statement of Shmuel, and Shmuel does not agree with the opinion of Rabbi Yosei, son of Rabbi Ḥanina, as this is what Rabbi Ya’akov bar Naḥmani said that Shmuel said: The case of: Most of the external rumen was torn, mentioned in the mishna, where the animal is a tereifa, is not referring to where the flesh enveloping the majority of the rumen was torn, but rather where the majority of the rumen itself was torn. The internal rumen is the place in the rumen that has no wool, i.e., downy projections on the inside of the rumen. Accordingly, one cannot prove anything about the statement of Shmuel based on an explanation of the mishna offered by Rabbi Yosei, son of Rabbi Ḥanina.
וּדְרוּסַת הַזְּאֵב. אָמַר רַב יְהוּדָה אָמַר רַב: בִּבְהֵמָה – מִן הַזְּאֵב וּלְמַעְלָה, וּבְעוֹפוֹת – מִן הַנֵּץ וּלְמַעְלָה.
§ The mishna states: And an animal that was clawed by a wolf is a tereifa. Rav Yehuda says that Rav says: In the case of an animal, it is a tereifa if it was clawed by any predator from the size of a wolf and upward. And with regard to birds, they are tereifot if they were clawed by any predator from the size of a hawk and upward.
לְמַעוֹטֵי מַאי? אִילֵּימָא לְמַעוֹטֵי חָתוּל – תְּנֵינָא: ״וּדְרוּסַת הַזְּאֵב״, וְכִי תֵּימָא הָא קָא מַשְׁמַע לַן דִּזְאֵב בְּגַסָּה נָמֵי דָּרֵיס – וְהָא תְּנַן: רַבִּי יְהוּדָה אוֹמֵר: דְּרוּסַת הַזְּאֵב בַּדַּקָּה, וּדְרוּסַת אֲרִי בַּגַּסָּה!
The Gemara asks: What does this statement of Rav, that an animal is a tereifa if it was clawed by a predator at least as large as a wolf, serve to exclude? If we say it serves to exclude a cat that clawed an animal, since it is smaller than a wolf, we already learned in the mishna: And an animal clawed by a wolf is a tereifa. One can infer from this that cats do not render an animal a tereifa. And if you would say: This mishna teaches us that a wolf can also effectively claw a large animal, e.g., cattle, but it may still be that a cat can render a small animal a tereifa, this cannot be; didn’t we learn in the mishna that Rabbi Yehuda says: If it was clawed by a wolf in the case of a small animal, or clawed by a lion in the case of a large animal, the animal is a tereifa?
וְכִי תֵּימָא, רַבִּי יְהוּדָה מִפְלָג פְּלִיג, וְהָאָמַר רַבִּי בִּנְיָמִין בַּר יֶפֶת אָמַר רַבִּי אִלְעָא: לֹא בָּא רַבִּי יְהוּדָה אֶלָּא לְפָרֵשׁ דִּבְרֵי חֲכָמִים!
And if you would say that Rabbi Yehuda disagrees with the Rabbis, and they hold that a wolf can also render large livestock tereifa by clawing, this too is impossible, as doesn’t Rabbi Binyamin bar Yefet say that Rabbi Ela says: The statement of Rabbi Yehuda in the mishna comes only to explain the statement of the Rabbis?
גַּבְרָא אַגַּבְרָא קָא רָמֵית? אִיבָּעֵית אֵימָא: לְעוֹלָם לְמַעוֹטֵי חָתוּל, מַהוּ דְּתֵימָא אוֹרְחָא דְּמִלְּתָא קָתָנֵי, קָא מַשְׁמַע לַן.
The Gemara responds: Are you setting the statement of one man against the statement of another man? Even if Rabbi Ela holds that Rabbi Yehuda comes only to explain the statement of the Rabbis, Rav may still hold that Rabbi Yehuda disagrees with the Rabbis. Or, if you wish, say instead: Actually, everyone agrees that a wolf can render only a small animal a tereifa through clawing. Nevertheless, the statement of Rav serves to exclude a cat from the ability to render even a small animal a tereifa. Lest you say that the mishna taught about a wolf only because this is the manner in which the matter typically occurs, but a cat may in fact render a small animal a tereifa, Rav teaches us that it is referring specifically to a wolf.
אָמַר רַב עַמְרָם אָמַר רַב חִסְדָּא: דְּרוּסַת חָתוּל וּנְמִיָּיה בִּגְדָיִים וּטְלָאִים, דְּרוּסַת חוּלְדָּה בְּעוֹפוֹת. מֵיתִיבִי: דְּרוּסַת חָתוּל, נֵץ וּנְמִיָּיה עַד שֶׁתִּינָּקֵב לֶחָלָל, אֲבָל דְּרוּסָה לֵית לְהוּ!
§ Rav Amram says that Rav Ḥisda says: If an animal was clawed by a cat or a mongoose, in the case of kids or lambs, which are very small, it is a tereifa. If it was clawed by a weasel in the case of birds, it is a tereifa. The Gemara raises an objection from a baraita: An animal clawed by a cat, hawk, or mongoose is not rendered a tereifa until one of its internal organs is perforated to its recesses. One may infer: But they, i.e., a cat, hawk, and mongoose, do not have the ability to render an animal a tereifa through the clawing itself.
וְתִסְבְּרָא נֵץ לָא דָּרֵיס? וְהָתְנַן: וּדְרוּסַת הַנֵּץ! הָא לָא קַשְׁיָא: כָּאן בְּעוֹפוֹת, כָּאן בִּגְדָיִים וּטְלָאִים.
The Gemara questions the inference: And can you understand that a hawk does not effectively claw an animal? But didn’t we learn in the mishna: And a small bird clawed by a hawk is rendered a tereifa? The Gemara responds: That is not difficult. Here, where the mishna states that a hawk can effectively claw, it is with regard to birds, while there, where the baraita states that a hawk does not effectively claw, it is with regard to kids and lambs.
מִכׇּל מָקוֹם, לְרַב חִסְדָּא קַשְׁיָא, הוּא דְּאָמַר כִּי הַאי תַּנָּא, דְּתַנְיָא: בְּרִיבִּי אוֹמֵר: לֹא אָמְרוּ אֵין דְּרוּסָה אֶלָּא בְּמָקוֹם שֶׁאֵין מַצִּילִין, אֲבָל בִּמְקוֹם שֶׁיֵּשׁ מַצִּילִין – יֵשׁ דְּרוּסָה.
The Gemara returns to its initial objection: In any case, the baraita poses a difficulty for Rav Ḥisda, who says that a cat may render kids and lambs tereifot through clawing. The Gemara responds: Rav Ḥisda states his opinion in accordance with the opinion of that tanna, as it is taught in a baraita: The Distinguished One says: They said that a kid is not effectively clawed by a cat only in a place where there are none present to save it. But in a place where there are bystanders trying to save the kid, it is effectively clawed, since the cat is angered and injects venom into the wound. Rav Ḥisda is referring specifically to the latter case.
וּבִמְקוֹם שֶׁאֵין מַצִּילִין אֵין דְּרוּסָה? וְהָא הָהִיא (תרנגולת) [תַּרְנְגוֹלְתָּא] דַּהֲוַאי בֵּי רַב כָּהֲנָא, דִּרְהַט חָתוּל בָּתְרַהּ, וְעָל לְאִידְּרוֹנָא, וְאִיתְּחִיד דַּשָּׁא בְּאַפֵּיהּ, וּמַחְיֵיהּ לְדַשָּׁא בְּסִיחוּפֵיהּ, וְאִשְׁתְּכַח עֲלַהּ חַמְשָׁה קוּרְטֵי דְּמָא!
The Gemara asks: And in a place where there are none to save the kid, is it not effectively clawed? But there was a certain hen that was in the house of Rav Kahana, which a cat pursued, and the cat entered after it into a small room, and the door shut in the cat’s face, and it struck the door with its paws in anger. And afterward, five drops of blood, i.e., venom, were found on the door. Apparently a cat is venomous even if no one is present to save its prey.
הַצָּלַת עַצְמָהּ נָמֵי כְּהַצָּלַת אֲחֵרִים דָּמֵי, וְרַבָּנַן – זִיהֲרָא אִית לֵיהּ, וְלָא קָלֵי זִיהֲרֵיהּ.
The Gemara responds: For a cat, saving itself is also considered like saving others. Since the cat felt threatened, it acted as it would if there had been someone present to defend the hen. The Gemara asks: And the Rabbis, who state in the baraita that a cat can never effectively claw a small animal, even when there are bystanders attempting to save its prey, how do they explain this incident? The Gemara responds: According to the Rabbis, a cat does have venom, but its venom does not burn enough to render the animal a tereifa.
אִיכָּא דְאָמְרִי: הָא מַנִּי? בְּרִיבִּי הִיא, דְּתַנְיָא: בְּרִיבִּי אוֹמֵר: לֹא אָמְרוּ יֵשׁ דְּרוּסָה אֶלָּא בִּמְקוֹם שֶׁיֵּשׁ מַצִּילִין, אֲבָל בִּמְקוֹם שֶׁאֵין מַצִּילִין – אִין דְּרוּסָה.
There are those who state the details of this exchange differently: After raising an objection to the statement of Rav Ḥisda from the baraita that states that a cat cannot effectively claw kids and lambs, the Gemara responds: In accordance with whose opinion is this baraita? It is in accordance with the opinion of the Distinguished One, as it is taught in a baraita: The Distinguished One says: They said that a kid is effectively clawed by a cat only in a place where there are bystanders present to save it. But in a place where there are none present to save the kid, it is not effectively clawed. The baraita, then, discusses a case where there are none present to save it. Rav Ḥisda agrees with the Rabbis that a cat can effectively claw an animal even when there are none present to save it.
וּבִמְקוֹם שֶׁאֵין מַצִּילִין אֵין דְּרוּסָה? וְהָא הָהִיא (תרנגולת) [תַּרְנְגוֹלְתָּא] דַּהֲוַאי בֵּי רַב כָּהֲנָא, דִּרְהַט חָתוּל בָּתְרַהּ וְעַל לְאִידְּרוֹנָא, וְאִיתְּחִיד דַּשָּׁא בְּאַפֵּיהּ, וּמַחְיֵיהּ לְדַשָּׁא בְּסִיחוּפֵיהּ, וְאִישְׁתְּכַח עֲלֵיהּ חֲמִשָּׁה קוּרְטֵי דְּמָא. הַצָּלַת עַצְמָהּ נָמֵי כְּהַצָּלַת אֲחֵרִים דָּמְיָא.
The Gemara asks: But in a place where there are none present to save the kid, is it not effectively clawed? But there was a certain hen that was in the house of Rav Kahana, which a cat pursued, and the cat entered after it into a small room, and the door shut in the cat’s face, and it struck the door with its paws in anger. And afterward, five drops of blood, i.e., venom, were found on the door. The Gemara responds: For a cat, saving itself is also considered like saving others.

The Hadran Women’s Tapestry
Meet the diverse women learning Gemara at Hadran and hear their stories.
I was inspired to start learning after attending the 2020 siyum in Binyanei Hauma. It has been a great experience for me. It’s amazing to see the origins of stories I’ve heard and rituals I’ve participated in my whole life. Even when I don’t understand the daf itself, I believe that the commitment to learning every day is valuable and has multiple benefits. And there will be another daf tomorrow!
Jerusalem, Israel
When I was working and taking care of my children, learning was never on the list. Now that I have more time I have two different Gemora classes and the nach yomi as well as the mishna yomi daily.

I read Ilana Kurshan’s “If All the Seas Were Ink” which inspired me. Then the Women’s Siyum in Jerusalem in 2020 convinced me, I knew I had to join! I have loved it- it’s been a constant in my life daily, many of the sugiyot connect to our lives. My family and friends all are so supportive. It’s incredible being part of this community and love how diverse it is! I am so excited to learn more!

In January 2020 on a Shabbaton to Baltimore I heard about the new cycle of Daf Yomi after the siyum celebration in NYC stadium. I started to read “ a daily dose of Talmud “ and really enjoyed it . It led me to google “ do Orthodox women study Talmud? “ and found HADRAN! Since then I listen to the podcast every morning, participate in classes and siyum. I love to learn, this is amazing! Thank you

It’s hard to believe it has been over two years. Daf yomi has changed my life in so many ways and has been sustaining during this global sea change. Each day means learning something new, digging a little deeper, adding another lens, seeing worlds with new eyes. Daf has also fostered new friendships and deepened childhood connections, as long time friends have unexpectedly become havruta.

I began learning the daf in January 2022. I initially “flew under the radar,” sharing my journey with my husband and a few close friends. I was apprehensive – who, me? Gemara? Now, 2 years in, I feel changed. The rigor of a daily commitment frames my days. The intellectual engagement enhances my knowledge. And the virtual community of learners has become a new family, weaving a glorious tapestry.

Years ago, I attended the local Siyum HaShas with my high school class. It was inspiring! Through that cycle and the next one, I studied masekhtot on my own and then did “daf yomi practice.” The amazing Hadran Siyum HaShas event firmed my resolve to “really do” Daf Yomi this time. It has become a family goal. We’ve supported each other through challenges, and now we’re at the Siyum of Seder Moed!
Jerusalem, Israel
I began daf yomi in January 2020 with Brachot. I had made aliya 6 months before, and one of my post-aliya goals was to complete a full cycle. As a life-long Tanach teacher, I wanted to swim from one side of the Yam shel Torah to the other. Daf yomi was also my sanity through COVID. It was the way to marking the progression of time, and feel that I could grow and accomplish while time stopped.
Givat Zev, Israel
I am grateful for the structure of the Daf Yomi. When I am freer to learn to my heart’s content, I learn other passages in addition. But even in times of difficulty, I always know that I can rely on the structure and social support of Daf Yomi learners all over the world.
I am also grateful for this forum. It is very helpful to learn with a group of enthusiastic and committed women.

In early January of 2020, I learned about Siyyum HaShas and Daf Yomi via Tablet Magazine’s brief daily podcast about the Daf. I found it compelling and fascinating. Soon I discovered Hadran; since then I have learned the Daf daily with Rabbanit Michelle Cohen Farber. The Daf has permeated my every hour, and has transformed and magnified my place within the Jewish Universe.

I started learning Daf Yomi in January 2020 after watching my grandfather, Mayer Penstein z”l, finish shas with the previous cycle. My grandfather made learning so much fun was so proud that his grandchildren wanted to join him. I was also inspired by Ilana Kurshan’s book, If All the Seas Were Ink. Two years in, I can say that it has enriched my life in so many ways.

Since I started in January of 2020, Daf Yomi has changed my life. It connects me to Jews all over the world, especially learned women. It makes cooking, gardening, and folding laundry into acts of Torah study. Daf Yomi enables me to participate in a conversation with and about our heritage that has been going on for more than 2000 years.

My Daf journey began in August 2012 after participating in the Siyum Hashas where I was blessed as an “enabler” of others. Galvanized into my own learning I recited the Hadran on Shas in January 2020 with Rabbanit Michelle. That Siyum was a highlight in my life. Now, on round two, Daf has become my spiritual anchor to which I attribute manifold blessings.

Retirement and Covid converged to provide me with the opportunity to commit to daily Talmud study in October 2020. I dove into the middle of Eruvin and continued to navigate Seder Moed, with Rabannit Michelle as my guide.

If the bird fell on fine sand, we need not be concerned, because the sand slides on impact, cushioning the fall. If it fell on coarse sand, we must be concerned, because there are large stones mixed into it. If it fell on dust of the road, we must be concerned, because the dust is compact and hard. If the bird fell on bundled straw, we must be concerned, because it is compact and hard. If the straw was not bundled, we need not be concerned.
חִיטֵּי וְכֹל דְּמִינַיְיהוּ – חָיְישִׁינַן; שְׂעָרֵי וְכֹל דְּמִינַיְיהוּ – חָיְישִׁינַן; כׇּל מִינֵי קִטְנִיּוֹת – אֵין בָּהֶם מִשּׁוּם רִיסּוּקֵי אֵבָרִים, לְבַר מִן רוּבְּיָא. חִימְצֵי – אֵין בּוֹ מִשּׁוּם רִיסּוּק אֵבָרִים, חִפְצֵי – יֵשׁ בּוֹ מִשּׁוּם רִיסּוּק אֵבָרִים. כְּלָלָא דְּמִלְּתָא: כֹּל מִידֵּי דְּמַשְׁרֵיק – אֵין בּוֹ מִשּׁוּם רִיסּוּק אֵבָרִים, לָא מַשְׁרֵיק – יֵשׁ בּוֹ מִשּׁוּם רִיסּוּק אֵבָרִים.
If the bird fell on wheat and all similar types of grain, such as spelt or rye, whose kernels are hard, we must be concerned. If it fell on barley and all similar types of grain, such as oats, we must be concerned. With regard to all types of beans, there is no concern due to possible shattered limbs if a bird fell on them, since their round shape causes the bird to slide when it hits them, except for fenugreek. With regard to peas, there is no concern due to possible shattered limbs, but with regard to chickpeas, there is a concern due to possible shattered limbs. The principle of the matter is: With regard to anything that slips to the sides on impact, there is no concern due to possible shattered limbs. And with regard to anything that does not slip, there is a concern due to possible shattered limbs.
דָּבוֹק – רַב אָשֵׁי שָׁרֵי, אַמֵּימָר אָסַר. בְּחַד גַּפָּא – דְּכוּלֵּי עָלְמָא לָא פְּלִיגִי דִּשְׁרֵי, כִּי פְּלִיגִי בִּתְרֵי גַּפֵּי. מַאן דְּאָסַר אָמַר לָךְ: הֵיכִי נֵיקוּם? וּמַאן דְּשָׁרֵי אָמַר לָךְ: אֶפְשָׁר דְּנֵיקוּם אַעִיקְבֵי דְּגַפֵּי.
If the bird’s wings became stuck to a davuk, a board covered with glue set as a trap, and in trying to escape it fell to the ground while stuck to the board, Rav Ashi deemed the bird permitted, while Ameimar deemed it prohibited. The Gemara explains: In a case where only one wing was stuck to the board, everyone agrees that it is permitted, because the bird flaps with the other wing, lessening the impact of the fall. They disagree when both wings are stuck to the board. The one who deemed it prohibited could have said to you: How will it stand itself up so that it might dampen the impact? And the one who deemed it permitted could have said to you: It is possible for it to stand itself up by using the tips of its wings.
וְאִיכָּא דְּאָמְרִי: בִּתְרֵי גַּפֵּי כּוּלֵּי עָלְמָא לָא פְּלִיגִי דַּאֲסִיר, כִּי פְּלִיגִי בְּחַד גַּפָּא. מַאן דְּשָׁרֵי אָמַר לָךְ: אֶפְשָׁר דְּפָרַח בְּחַד גַּפָּא, וּמַאן דְּאָסַר: כֵּיוָן דִּבְהַאי לָא מָצֵי פָּרַח, בְּהַאי נָמֵי לָא מָצֵי פָּרַח. וְהִילְכְתָא: בִּתְרֵי גַּפֵּי אֲסִיר, בְּחַד גַּפָּא שְׁרֵי.
And there are those who say: In a case where two wings were stuck to the board, everyone agrees that it is prohibited, because it cannot dampen the impact. They disagree when only one wing is stuck to the board. The one who deemed it permitted could have said to you: It is possible for it to fly with one wing and dampen the fall. And the one who deemed it prohibited could say: Since it cannot fly with this wing that is stuck to the davuk, it also cannot fly with that untrapped wing. The Gemara concludes: And the halakha is: In a case where two wings were stuck, it is prohibited. In a case where only one wing was stuck, it is permitted.
נִשְׁתַּבְּרוּ רוֹב צַלְעוֹתֶיהָ. תָּנוּ רַבָּנַן: אֵלּוּ הֵן רוֹב צְלָעוֹת – שֵׁשׁ מִכָּאן וְשֵׁשׁ מִכָּאן, אוֹ אַחַת עֶשְׂרֵה מִכָּאן וְאַחַת מִכָּאן.
§ The mishna states that if most of an animal’s ribs were fractured, it is a tereifa. The Sages taught: These are most of the ribs: Six from here and six from there, i.e., six on each side, or eleven from here and one from there. Twenty-two ribs are significant for matters of tereifot, eleven on each side. Twelve fractured ribs constitutes a majority.
אָמַר זְעֵירִי: וּמֵחֶצְיָין כְּלַפֵּי שִׁדְרָה. אָמַר רַבָּה בַּר בַּר חָנָה אָמַר רַבִּי יוֹחָנָן: וּבִצְלָעוֹת גְּדוֹלוֹת שֶׁיֵּשׁ בָּהֶן מוֹחַ.
Ze’eiri says: And this applies only when the ribs were fractured from the half of the rib toward the spine, but not if they were fractured on the other half. Rabba bar bar Ḥana says that Rabbi Yoḥanan says: And this applies only to fractures occurring in large ribs that contain marrow; fractures in small ribs do not render the animal a tereifa.
אָמַר עוּלָּא, בֶּן זַכַּאי אָמַר: נֶעְקְרוּ – בְּרוֹב צַד אֶחָד, נִשְׁתַּבְּרוּ – בְּרוֹב שְׁנֵי צְדָדִין. רַבִּי יוֹחָנָן אָמַר: בֵּין נֶעְקְרוּ בֵּין נִשְׁתַּבְּרוּ – בְּרוֹב שְׁנֵי צְדָדִין.
§ Ulla said that ben Zakkai says: If the ribs were dislocated from the spine, even a majority of one side, i.e., six dislocated ribs, is enough to render the animal a tereifa. Only if the ribs were broken is a majority of both sides necessary. Rabbi Yoḥanan says: Whether they were dislocated or broken, the animal is a tereifa only with a majority of both sides.
אָמַר רַב: נֶעֶקְרָה צֵלָע וְחוּלְיָא עִמָּהּ – טְרֵפָה. אָמְרִי לֵיהּ רַב כָּהֲנָא וְרַב אַסִּי לְרַב: נֶעֶקְרָה צֵלָע מִכָּאן וְצֵלָע מִכָּאן, וְחוּלְיָא קַיֶּימֶת, מַהוּ? אֲמַר לְהוּ: גִּיסְטְרָא קָאָמְרִיתוּ?!
Rav says: If a rib was dislocated and the attached vertebra was torn out with it, the animal is a tereifa, even if the spinal cord remains intact. Rav Kahana and Rav Asi said to Rav: If a rib was dislocated from here and another rib from there, i.e., both ribs connected to a single vertebra were dislocated, but the vertebra itself remains intact, what is the halakha? Rav said to them: Are you saying that an animal that was sliced in half is a tereifa? This animal is considered to have been sliced and already has the status of a carcass, as it is already considered dead (see 21a).
וְהָא רַב נָמֵי גִּיסְטְרָא קָאָמַר? כִּי קָאָמַר רַב – צֵלָע בְּלֹא חוּלְיָא.
The Gemara asks: But didn’t Rav also say that a sliced animal is a tereifa, since he said that if a rib was dislocated along with the attached vertebra, the animal is a tereifa? In such a case, the opposite rib is inevitably detached. If so, the animal should be considered a carcass. The Gemara responds: When Rav said that such an animal is a tereifa, he was referring to a case where the rib was dislocated without the vertebra.
וְהָא צֵלָע וְחוּלְיָא קָאָמַר? צֵלָע וַחֲצִי חוּלְיָא.
The Gemara asks: But didn’t Rav explicitly say his statement with regard to a rib and vertebra that were dislocated? The Gemara responds: Rav meant that if a rib and half its attached vertebra were dislocated, the animal is a tereifa. The opposite rib, however, is intact and connected to the remainder of the vertebra.
מִכְּלָל דְּרַב כָּהֲנָא וְרַב אַסִּי, צֵלָע בְּלֹא חוּלְיָא אָמְרִי, וַאֲמַר לְהוּ: ״גִּיסְטְרָא קָאָמְרִיתוּ״? וְהָאָמַר עוּלָּא: בֶּן זַכַּאי אָמַר: נֶעְקְרוּ – בְּרוֹב צַד אֶחָד, נִשְׁתַּבְּרוּ – בְּרוֹב שְׁנֵי צְדָדִין.
The Gemara challenges: By inference, one may conclude that Rav Kahana and Rav Asi stated their question with regard to a less serious case, i.e., where a rib from each side was torn out without the vertebra being damaged at all. And yet, Rav said to them: Are you saying that an animal that was sliced in half is a tereifa? Rather, this animal is a carcass and is certainly prohibited. And how could Rav say this? But didn’t Ulla say that ben Zakkai says: If the ribs were dislocated, even a majority of one side is enough to render the animal a tereifa, while if the ribs were broken, a majority of both sides is necessary? If so, any animal with fewer than six dislocated ribs should be kosher, as long as the spine is undamaged.
אָמַר לָךְ: הָתָם זֶה שֶׁלֹּא כְּנֶגֶד זֶה, הָכָא זֶה כְּנֶגֶד זֶה.
The Gemara responds: Rav could have said to you: There, where ben Zakkai says that six dislocated ribs on one side render the animal a tereifa, this is referring only to ribs not dislocated one opposite the other. Here, where Rav says that two dislocated ribs render the animal a carcass, this is referring to ribs dislocated one opposite the other.
וְהָאָמַר רַבִּי יוֹחָנָן: בְּרוֹב שְׁנֵי צְדָדִין, וּבְרוֹב שְׁנֵי צְדָדִין אִי אֶפְשָׁר דְּלָא קָיְימָא (חד) [חֲדָא] מִינַּיְיהוּ זֶה כְּנֶגֶד זֶה!
The Gemara asks: But doesn’t Rabbi Yoḥanan say that the animal is a tereifa only if a majority of both sides was dislocated, and in a majority of both sides, it is impossible that one of them is not situated opposite another? Still, Rabbi Yoḥanan says that the animal is a tereifa and not a carcass.
הָתָם – בּוּכְנָא בְּלָא אֲסִיתָא, הָכָא – בּוּכְנָא וַאֲסִיתָא.
The Gemara responds: There, Rabbi Yoḥanan is referring to a case where the pestle, i.e., the end of the rib, was torn out without the mortar, the socket of the vertebra in which it sits, leaving the spine completely intact. In such a case, the animal is a tereifa only if twelve ribs were dislocated, even though this necessarily includes one rib opposite another. Here, where Rav says that two dislocated ribs opposite one another render the animal a carcass, that is referring to a case where the pestle and mortar were torn out together, damaging the spine.
אִי הָכִי, הַיְינוּ דְּרַב? לָא שְׁמִיעַ לְהוּ דְּרַב.
The Gemara asks: If so, why did Rav Kahana and Rav Asi ask anything of Rav? Their case in question is identical to the statement of Rav. If Rav says that the animal is a tereifa if a rib and part of its vertebra were dislocated, that should be the halakha all the more so if ribs opposite one another were dislocated in addition to part of the attached vertebra. The Gemara responds: Rav Kahana and Rav Asi did not hear that statement of Rav.
וְלִיבְעוֹ מִינֵּיהּ כִּדְרַב? סָבְרִי: לִיבְעֵי מִינֵּיהּ חֲדָא דְּפָרֵישׁ לַן תַּרְתֵּי, דְּאִי בָּעֵינַן מִינֵּיהּ חֲדָא, הָנִיחָא אִי אֲמַר לַן ״טְרֵפָה״ – כׇּל שֶׁכֵּן תַּרְתֵּי, אִי אֲמַר לַן ״כְּשֵׁרָה״ – אַכַּתִּי תַּרְתֵּי קָא מִיבַּעְיָא לַן.
The Gemara persists: But if so, let them ask about the simpler case of one dislocated rib, like that which Rav himself discussed. Why ask specifically about two ribs opposite one another? The Gemara responds: They reasoned: Let us ask him one question through which he will explain to us two different cases. As, if we ask him about only one dislocated rib, this works out well if he says to us that the animal is a tereifa, because we can infer that all the more so if two ribs opposite one another are dislocated, the animal is a tereifa. But if he says to us that it is kosher, we must still ask with regard to a case of two dislocated ribs.
אִי הָכִי, הַשְׁתָּא נָמֵי דְּקָא בָּעֵי מִינֵּיהּ תַּרְתֵּי, הָנִיחָא אִי אֲמַר לְהוּ ״כְּשֵׁרָה״ – כׇּל שֶׁכֵּן חֲדָא; וְאִי אֲמַר לְהוּ ״טְרֵפָה״, אַכַּתִּי חֲדָא מִיבַּעְיָא לְהוּ.
The Gemara objects: If that is so, then now, too, when they ask him about two ribs, they may not receive an answer with regard to both cases. Granted, this works out well if he says to them that an animal with two dislocated ribs opposite one another is kosher, since they can infer that all the more so it is kosher if only one rib is dislocated. But if he says to them that it is a tereifa, they must still ask with regard to a case of only one dislocated rib.
סָבְרִי: אִם כֵּן מִירְתָּח קָא רָתַח. חֲדָא טְרֵפָה, תַּרְתֵּי מִיבַּעְיָא?
The Gemara responds: They reasoned that it is better to ask about a case where two ribs opposite one another were dislocated, because if it is so that Rav holds that the animal is a tereifa if even one rib is dislocated, then he would become angry and respond: If an animal with even one dislocated rib is a tereifa, is it necessary to ask about an animal with two dislocated ribs?
וְהָא קָא אָמְרִי לֵיהּ וְלָא רָתַח, כֵּיוָן דְּקָאָמַר לְהוּ ״גִּיסְטְרָא קָאָמְרִיתוּ״ – הַיְינוּ רִיתְחֵיהּ.
The Gemara objects: But they did say this question to him and he did not become angry, despite the fact that he holds that even one dislocated rib renders the animal a tereifa. The Gemara responds: When he said to them: Are you saying that an animal that was sliced in half is a tereifa, this is his anger. Rav Kahana and Rav Asi understood from this response that an animal with two dislocated ribs opposite one another is a carcass, but an animal with one dislocated rib is a tereifa.
אָמַר רַבָּה בַּר רַב שֵׁילָא אָמַר רַב מַתְנָא אָמַר שְׁמוּאֵל: נֶעֶקְרָה צֵלָע מֵעִיקָּרָהּ, וְגוּלְגּוֹלֶת שֶׁנֶּחְבְּסָה בְּרוּבָּה, וּבָשָׂר הַחוֹפֶה אֶת רוֹב הַכָּרֵס בְּרוּבּוֹ – טְרֵפָה.
§ Rabba bar Rav Sheila says that Rav Mattana says that Shmuel says: If a rib was ripped from its root, or if the skull was crushed in its majority, or if the flesh that envelops the majority of the rumen was damaged in its majority, the animal is a tereifa.
נֶעֶקְרָה צֵלָע מֵעִיקָּרָהּ טְרֵפָה? וּרְמִינְהוּ:
The Gemara asks: Did Shmuel really say that if a rib was ripped from its root, the animal is a tereifa? But raise a contradiction from a mishna (Oholot 2:3):
כַּמָּה חִסָּרוֹן בְּשִׁדְרָה? בֵּית שַׁמַּאי אוֹמְרִים: שְׁתֵּי חוּלְיוֹת, וּבֵית הִלֵּל אוֹמְרִים: חוּלְיָא אַחַת, וְאָמַר רַב יְהוּדָה אָמַר שְׁמוּאֵל: וְכֵן לִטְרֵפָה.
How much is considered a deficiency in the spine of a corpse so that it will not be considered a full corpse that would render one impure in a tent? Beit Shammai say: Two missing vertebrae, and Beit Hillel say: One vertebra. And Rav Yehuda says that Shmuel says: And just as Beit Shammai and Beit Hillel disagree with regard to ritual impurity, so too they disagree with regard to a tereifa, i.e., according to Beit Hillel an animal missing only one vertebra is a tereifa. Evidently, Shmuel holds that a missing vertebra renders the animal a tereifa, but a dislocated rib does not.
הָכָא – צֵלָע בְּלֹא חוּלְיָא, הָתָם – חוּלְיָא בְּלֹא צֵלָע.
The Gemara responds: This is not difficult. Here, where Shmuel says that a rib ripped from its root renders the animal a tereifa, he is referring to a case where the rib was torn out without the vertebra. There, where he says that a missing vertebra renders the animal a tereifa according to Beit Hillel, he is referring to a case where the vertebra was missing without the rib being dislocated. But if the rib itself was ripped from its root, the animal is a tereifa.
בִּשְׁלָמָא צֵלָע בְּלֹא חוּלְיָא – מַשְׁכַּחַתְּ לַהּ, אֶלָּא חוּלְיָא בְּלֹא צֵלָע – הֵיכִי מַשְׁכַּחַתְּ לַהּ? בְּשִׁילְהֵי כַּפְלֵי.
The Gemara asks: Granted, with regard to a case where a rib was dislocated without the vertebra, you find this commonly. But how can you find a case of a missing vertebra without a dislocated rib? The Gemara responds: This can occur at the ends of the flanks, where there are vertebrae with no ribs attached to them.
מַתְקֵיף לַהּ רַב אוֹשַׁעְיָא: וְלִתְנְיַיהּ גַּבֵּי קוּלֵּי בֵּית שַׁמַּאי וְחוּמְרֵי בֵּית הִלֵּל? אֲמַר לֵיהּ רַב: כִּי אִיתְּשִׁיל – לְעִנְיַן טוּמְאָה אִיתְּשִׁיל, דְּהָווּ לְהוּ בֵּית שַׁמַּאי לְחוּמְרָא.
Shmuel said that just as Beit Shammai and Beit Hillel disagree with regard to ritual impurity, so too they disagree with regard to a tereifa. Rav Oshaya objects to this statement: But if that is so, then the opinion of Beit Hillel is the more stringent one, as they hold that even one missing vertebra renders the animal a tereifa. Accordingly, let the tanna teach this dispute along with the list of leniencies of Beit Shammai and stringencies of Beit Hillel in tractate Eduyyot. Rav said to him: When the question was asked, it was asked with regard to the ritual impurity of a corpse. That is the source of the dispute between Beit Hillel and Beit Shammai, and on that matter, Beit Shammai constitute the stringent opinion. The parallel disagreement with regard to tereifot is not mentioned explicitly in any mishna or baraita, and it was therefore omitted from the list in tractate Eduyyot.
וְגוּלְגּוֹלֶת שֶׁנֶּחְבְּסָה בְּרוּבָּהּ. בָּעֵי רַבִּי יִרְמְיָה: רוֹב גּוֹבְהָהּ, אוֹ רוֹב הֶיקֵּיפָהּ? תֵּיקוּ.
The Gemara returns to Shmuel’s statement: Or if the skull was crushed in its majority, the animal is a tereifa. Rabbi Yirmeya raises a dilemma: Is this referring to the majority of its height or the majority of its circumference? The Gemara responds: The dilemma shall stand unresolved.
וּבָשָׂר הַחוֹפֶה רוֹב הַכָּרֵס בְּרוּבּוֹ. בָּעֵי רַב אָשֵׁי: בְּרוֹב קָרוּעַ, אוֹ בְּרוֹב נָטוּל?
Shmuel also said: Or if the flesh that envelops the majority of the rumen was damaged in its majority, the animal is a tereifa. Rav Ashi raises a dilemma: Is this referring even to a case where the majority of the length of the flesh was torn? Or is it referring only to a case where the majority of the flesh was removed, but if it was torn along the majority of its length the animal remains kosher?
תִּפְשׁוֹט לֵיהּ מִדִּתְנַן: כָּרֵס הַפְּנִימִית שֶׁנִּיקְּבָה, אוֹ שֶׁנִּקְרַע רוֹב הַחִיצוֹנָה, וְאָמְרִי בְּמַעְרְבָא מִשְּׁמֵיהּ דְּרַבִּי יוֹסֵי בְּרַבִּי חֲנִינָא: כׇּל הַכָּרֵס כּוּלּוֹ זוֹ הִיא כָּרֵס הַפְּנִימִי, וְאֵי זֶהוּ כָּרֵס הַחִיצוֹנָה? בָּשָׂר הַחוֹפֶה אֶת רוֹב הַכָּרֵס.
The Gemara responds: Resolve the dilemma from that which we learned in the mishna: If the internal rumen was perforated or most of the external rumen was torn, the animal is a tereifa. And in the West, Eretz Yisrael, they said in the name of Rabbi Yosei, son of Rabbi Ḥanina: The entire rumen is the internal rumen. And if so, which is the external rumen? It is the flesh that envelops the majority of the rumen. Apparently, the animal is a tereifa even if the flesh is torn in its majority.
מִידֵּי הוּא טַעְמָא, אֶלָּא לִשְׁמוּאֵל, הָכִי אָמַר רַבִּי יַעֲקֹב בַּר נַחְמָנִי אָמַר שְׁמוּאֵל: מָקוֹם שֶׁאֵין בּוֹ מֵילָת.
The Gemara rejects the proof: This explanation is meant only to clarify the statement of Shmuel, and Shmuel does not agree with the opinion of Rabbi Yosei, son of Rabbi Ḥanina, as this is what Rabbi Ya’akov bar Naḥmani said that Shmuel said: The case of: Most of the external rumen was torn, mentioned in the mishna, where the animal is a tereifa, is not referring to where the flesh enveloping the majority of the rumen was torn, but rather where the majority of the rumen itself was torn. The internal rumen is the place in the rumen that has no wool, i.e., downy projections on the inside of the rumen. Accordingly, one cannot prove anything about the statement of Shmuel based on an explanation of the mishna offered by Rabbi Yosei, son of Rabbi Ḥanina.
וּדְרוּסַת הַזְּאֵב. אָמַר רַב יְהוּדָה אָמַר רַב: בִּבְהֵמָה – מִן הַזְּאֵב וּלְמַעְלָה, וּבְעוֹפוֹת – מִן הַנֵּץ וּלְמַעְלָה.
§ The mishna states: And an animal that was clawed by a wolf is a tereifa. Rav Yehuda says that Rav says: In the case of an animal, it is a tereifa if it was clawed by any predator from the size of a wolf and upward. And with regard to birds, they are tereifot if they were clawed by any predator from the size of a hawk and upward.
לְמַעוֹטֵי מַאי? אִילֵּימָא לְמַעוֹטֵי חָתוּל – תְּנֵינָא: ״וּדְרוּסַת הַזְּאֵב״, וְכִי תֵּימָא הָא קָא מַשְׁמַע לַן דִּזְאֵב בְּגַסָּה נָמֵי דָּרֵיס – וְהָא תְּנַן: רַבִּי יְהוּדָה אוֹמֵר: דְּרוּסַת הַזְּאֵב בַּדַּקָּה, וּדְרוּסַת אֲרִי בַּגַּסָּה!
The Gemara asks: What does this statement of Rav, that an animal is a tereifa if it was clawed by a predator at least as large as a wolf, serve to exclude? If we say it serves to exclude a cat that clawed an animal, since it is smaller than a wolf, we already learned in the mishna: And an animal clawed by a wolf is a tereifa. One can infer from this that cats do not render an animal a tereifa. And if you would say: This mishna teaches us that a wolf can also effectively claw a large animal, e.g., cattle, but it may still be that a cat can render a small animal a tereifa, this cannot be; didn’t we learn in the mishna that Rabbi Yehuda says: If it was clawed by a wolf in the case of a small animal, or clawed by a lion in the case of a large animal, the animal is a tereifa?
וְכִי תֵּימָא, רַבִּי יְהוּדָה מִפְלָג פְּלִיג, וְהָאָמַר רַבִּי בִּנְיָמִין בַּר יֶפֶת אָמַר רַבִּי אִלְעָא: לֹא בָּא רַבִּי יְהוּדָה אֶלָּא לְפָרֵשׁ דִּבְרֵי חֲכָמִים!
And if you would say that Rabbi Yehuda disagrees with the Rabbis, and they hold that a wolf can also render large livestock tereifa by clawing, this too is impossible, as doesn’t Rabbi Binyamin bar Yefet say that Rabbi Ela says: The statement of Rabbi Yehuda in the mishna comes only to explain the statement of the Rabbis?
גַּבְרָא אַגַּבְרָא קָא רָמֵית? אִיבָּעֵית אֵימָא: לְעוֹלָם לְמַעוֹטֵי חָתוּל, מַהוּ דְּתֵימָא אוֹרְחָא דְּמִלְּתָא קָתָנֵי, קָא מַשְׁמַע לַן.
The Gemara responds: Are you setting the statement of one man against the statement of another man? Even if Rabbi Ela holds that Rabbi Yehuda comes only to explain the statement of the Rabbis, Rav may still hold that Rabbi Yehuda disagrees with the Rabbis. Or, if you wish, say instead: Actually, everyone agrees that a wolf can render only a small animal a tereifa through clawing. Nevertheless, the statement of Rav serves to exclude a cat from the ability to render even a small animal a tereifa. Lest you say that the mishna taught about a wolf only because this is the manner in which the matter typically occurs, but a cat may in fact render a small animal a tereifa, Rav teaches us that it is referring specifically to a wolf.
אָמַר רַב עַמְרָם אָמַר רַב חִסְדָּא: דְּרוּסַת חָתוּל וּנְמִיָּיה בִּגְדָיִים וּטְלָאִים, דְּרוּסַת חוּלְדָּה בְּעוֹפוֹת. מֵיתִיבִי: דְּרוּסַת חָתוּל, נֵץ וּנְמִיָּיה עַד שֶׁתִּינָּקֵב לֶחָלָל, אֲבָל דְּרוּסָה לֵית לְהוּ!
§ Rav Amram says that Rav Ḥisda says: If an animal was clawed by a cat or a mongoose, in the case of kids or lambs, which are very small, it is a tereifa. If it was clawed by a weasel in the case of birds, it is a tereifa. The Gemara raises an objection from a baraita: An animal clawed by a cat, hawk, or mongoose is not rendered a tereifa until one of its internal organs is perforated to its recesses. One may infer: But they, i.e., a cat, hawk, and mongoose, do not have the ability to render an animal a tereifa through the clawing itself.
וְתִסְבְּרָא נֵץ לָא דָּרֵיס? וְהָתְנַן: וּדְרוּסַת הַנֵּץ! הָא לָא קַשְׁיָא: כָּאן בְּעוֹפוֹת, כָּאן בִּגְדָיִים וּטְלָאִים.
The Gemara questions the inference: And can you understand that a hawk does not effectively claw an animal? But didn’t we learn in the mishna: And a small bird clawed by a hawk is rendered a tereifa? The Gemara responds: That is not difficult. Here, where the mishna states that a hawk can effectively claw, it is with regard to birds, while there, where the baraita states that a hawk does not effectively claw, it is with regard to kids and lambs.
מִכׇּל מָקוֹם, לְרַב חִסְדָּא קַשְׁיָא, הוּא דְּאָמַר כִּי הַאי תַּנָּא, דְּתַנְיָא: בְּרִיבִּי אוֹמֵר: לֹא אָמְרוּ אֵין דְּרוּסָה אֶלָּא בְּמָקוֹם שֶׁאֵין מַצִּילִין, אֲבָל בִּמְקוֹם שֶׁיֵּשׁ מַצִּילִין – יֵשׁ דְּרוּסָה.
The Gemara returns to its initial objection: In any case, the baraita poses a difficulty for Rav Ḥisda, who says that a cat may render kids and lambs tereifot through clawing. The Gemara responds: Rav Ḥisda states his opinion in accordance with the opinion of that tanna, as it is taught in a baraita: The Distinguished One says: They said that a kid is not effectively clawed by a cat only in a place where there are none present to save it. But in a place where there are bystanders trying to save the kid, it is effectively clawed, since the cat is angered and injects venom into the wound. Rav Ḥisda is referring specifically to the latter case.
וּבִמְקוֹם שֶׁאֵין מַצִּילִין אֵין דְּרוּסָה? וְהָא הָהִיא (תרנגולת) [תַּרְנְגוֹלְתָּא] דַּהֲוַאי בֵּי רַב כָּהֲנָא, דִּרְהַט חָתוּל בָּתְרַהּ, וְעָל לְאִידְּרוֹנָא, וְאִיתְּחִיד דַּשָּׁא בְּאַפֵּיהּ, וּמַחְיֵיהּ לְדַשָּׁא בְּסִיחוּפֵיהּ, וְאִשְׁתְּכַח עֲלַהּ חַמְשָׁה קוּרְטֵי דְּמָא!
The Gemara asks: And in a place where there are none to save the kid, is it not effectively clawed? But there was a certain hen that was in the house of Rav Kahana, which a cat pursued, and the cat entered after it into a small room, and the door shut in the cat’s face, and it struck the door with its paws in anger. And afterward, five drops of blood, i.e., venom, were found on the door. Apparently a cat is venomous even if no one is present to save its prey.
הַצָּלַת עַצְמָהּ נָמֵי כְּהַצָּלַת אֲחֵרִים דָּמֵי, וְרַבָּנַן – זִיהֲרָא אִית לֵיהּ, וְלָא קָלֵי זִיהֲרֵיהּ.
The Gemara responds: For a cat, saving itself is also considered like saving others. Since the cat felt threatened, it acted as it would if there had been someone present to defend the hen. The Gemara asks: And the Rabbis, who state in the baraita that a cat can never effectively claw a small animal, even when there are bystanders attempting to save its prey, how do they explain this incident? The Gemara responds: According to the Rabbis, a cat does have venom, but its venom does not burn enough to render the animal a tereifa.
אִיכָּא דְאָמְרִי: הָא מַנִּי? בְּרִיבִּי הִיא, דְּתַנְיָא: בְּרִיבִּי אוֹמֵר: לֹא אָמְרוּ יֵשׁ דְּרוּסָה אֶלָּא בִּמְקוֹם שֶׁיֵּשׁ מַצִּילִין, אֲבָל בִּמְקוֹם שֶׁאֵין מַצִּילִין – אִין דְּרוּסָה.
There are those who state the details of this exchange differently: After raising an objection to the statement of Rav Ḥisda from the baraita that states that a cat cannot effectively claw kids and lambs, the Gemara responds: In accordance with whose opinion is this baraita? It is in accordance with the opinion of the Distinguished One, as it is taught in a baraita: The Distinguished One says: They said that a kid is effectively clawed by a cat only in a place where there are bystanders present to save it. But in a place where there are none present to save the kid, it is not effectively clawed. The baraita, then, discusses a case where there are none present to save it. Rav Ḥisda agrees with the Rabbis that a cat can effectively claw an animal even when there are none present to save it.
וּבִמְקוֹם שֶׁאֵין מַצִּילִין אֵין דְּרוּסָה? וְהָא הָהִיא (תרנגולת) [תַּרְנְגוֹלְתָּא] דַּהֲוַאי בֵּי רַב כָּהֲנָא, דִּרְהַט חָתוּל בָּתְרַהּ וְעַל לְאִידְּרוֹנָא, וְאִיתְּחִיד דַּשָּׁא בְּאַפֵּיהּ, וּמַחְיֵיהּ לְדַשָּׁא בְּסִיחוּפֵיהּ, וְאִישְׁתְּכַח עֲלֵיהּ חֲמִשָּׁה קוּרְטֵי דְּמָא. הַצָּלַת עַצְמָהּ נָמֵי כְּהַצָּלַת אֲחֵרִים דָּמְיָא.
The Gemara asks: But in a place where there are none present to save the kid, is it not effectively clawed? But there was a certain hen that was in the house of Rav Kahana, which a cat pursued, and the cat entered after it into a small room, and the door shut in the cat’s face, and it struck the door with its paws in anger. And afterward, five drops of blood, i.e., venom, were found on the door. The Gemara responds: For a cat, saving itself is also considered like saving others.
בְּעָא מִינֵּיהּ רַב כָּהֲנָא מֵרַב:
The Gemara relates that Rav Kahana asked Rav:
