Does Rabbi Yossi really hold that impurity in an enclosed area without the space of a square handsbreadth above it, will not pass on impurities to one touching the space above it? According to Rabbi Yochanan, the mishna is in accordance with Rabbi Yossi holds that “touching” the space above an item that is impure (dead human) is called “touching” (meaning laws of covering is the same as laws of touching). Which tanna disagrees with him? Is a dead egg of a creeping animal impure? Does a mouse that is partially flesh and partially dirt (according to most, created by spontaneous generation) pass on impurities? If so, under what conditions?

Chullin 126
וְתָנֵי עֲלַהּ: רַבִּי יוֹסֵי מְטַהֵר. אַהֵיָיא? אִילֵּימָא אַסֵּיפָא – תַּנָּא קַמָּא נָמֵי טַהוֹרֵי קָא מְטַהַר!
And it is taught with regard to that halakha in the mishna that Rabbi Yosei deems it pure. To which halakha in the mishna is this referring? If we say that it is referring to the latter clause of the mishna, which discusses a chest placed in the entrance of the house, the first tanna also deems it pure in that case.
אֶלָּא, דְּקָאָמַר תַּנָּא קַמָּא: טוּמְאָה בְּתוֹכָהּ – הַבַּיִת טָמֵא, אִי מִשּׁוּם דְּדֶרֶךְ טוּמְאָה לָצֵאת, וְאִי מִשּׁוּם דְּטוּמְאָה טְמוּנָה בּוֹקַעַת. וְקָאָמַר לֵיהּ רַבִּי יוֹסֵי: וּדְקָאָמְרַתְּ דֶּרֶךְ טוּמְאָה לָצֵאת – יָכוֹל הוּא לְהוֹצִיאָהּ לַחֲצָאִין אוֹ לְשׂוֹרְפָהּ בִּמְקוֹמָהּ, וּדְקָאָמְרַתְּ טוּמְאָה טְמוּנָה בּוֹקַעַת – טוּמְאָה טְמוּנָה אֵינָהּ בּוֹקַעַת.
Rather, it is clear that the first tanna says that if a source of impurity is inside the compartment of a chest that is inside the house, the house is impure, either because it is typical for a source of impurity to exit its location, or because he holds that a hidden source of impurity breaks through and ascends. And Rabbi Yosei disagrees and says to him: With regard to that which you say that it is typical for a source of impurity to exit its location, it is not necessarily so. One can remove the impure item in halves or burn it in its place inside the compartment. And with regard to that which you say that a hidden source of impurity breaks through and ascends, a hidden source of impurity does not break through. Consequently, Rabbi Yosei must hold that a hidden source of impurity does not break through and ascend.
וְרָמֵי דְּרַבִּי יוֹסֵי אַדְּרַבִּי יוֹסֵי.
§Based on the previous statement of Rabbi Yosei, the Gemara established that Rabbi Yosei holds that a hidden source of impurity does not break through and ascend. And the Gemara raises a contradiction between that previous statement of Rabbi Yosei and another statement of Rabbi Yosei.
דִּתְנַן: הַכֶּלֶב שֶׁאָכַל בָּשָׂר מֵת, וּמֵת הַכֶּלֶב, וּמוּטָּל עַל הָאִסְקוּפָּה – רַבִּי מֵאִיר אוֹמֵר: אִם יֵשׁ בְּצַוָּארוֹ פּוֹתֵחַ טֶפַח – מֵבִיא אֶת הַטּוּמְאָה, וְאִם לָאו – אֵינוֹ מֵבִיא אֶת הַטּוּמְאָה.
As we learned in a mishna (Oholot 11:7): In the case of a dog that ate the flesh of a corpse, and the dog then died and is lying on the threshold in such a manner that its neck and mouth are facing toward the inside of the house, Rabbi Meir says: If there is an opening the size of one cubic handbreadth inside the neck of the dog, i.e., the neck itself constitutes this measure, the dog imports impurity into the house because the upper portion of the dog’s body overlies the impure item inside the dog and the impurity is transmitted through the neck and mouth of the dog into the house. But if there is not such a large cavity in the neck of the dog, then there is no halakha of a tent, and the dog does not import the impurity into the house.
רַבִּי יוֹסֵי אוֹמֵר: רוֹאִין מִכְּנֶגֶד הַשָּׁקוֹף וְלִפְנִים – הַבַּיִת טָמֵא, מִכְּנֶגֶד הַשְּׁקוֹף וְלַחוּץ – הַבַּיִת טָהוֹר.
Rabbi Yosei says: One looks to determine exactly where on the threshold the dog is located. If the impure item inside the dog is located anywhere from opposite, i.e., under, the lintel and toward the inside of the house, the house is impure. If the dog is located anywhere from opposite the lintel and toward the outside of the house, the house remains pure.
רַבִּי אֶלְעָזָר אוֹמֵר: פִּיו לִפְנִים הַבַּיִת – טָהוֹר, פִּיו לַחוּץ הַבַּיִת – טָמֵא, מִפְּנֵי שֶׁטּוּמְאָה יוֹצְאָה דֶּרֶךְ שׁוּלָיו.
Rabbi Elazar says: One must determine the exact manner in which the dog is lying on the threshold. If its mouth is located inside the house, but its rear is located outside the house, the house remains pure. If its mouth is located outside the house but its rear is located inside the house, the house is impure. This is because the source of impurity exits the dog’s body through its edge, i.e., its rear.
רַבִּי יְהוּדָה בֶּן בְּתִירָא אוֹמֵר: בֵּין כָּךְ וּבֵין כָּךְ, הַבַּיִת טָמֵא.
Rabbi Yehuda ben Beteira says: In both this case and that case, i.e., whether the dog is lying such that its mouth is inside the house or outside the house, the house is impure. The reason is that the impure item can exit through either the mouth or the rear.
מַאי לָאו, אַאֵין בְּצַוָּארוֹ פּוֹתֵחַ טֶפַח קָאֵי רַבִּי יוֹסֵי?
The Gemara analyzes the statement of Rabbi Yosei that if the dog is located anywhere from under the lintel and toward the inside of the house, the house is impure. What, is the statement of Rabbi Yosei not referring to a case where there is not an opening the size of one cubic handbreadth inside the dog’s neck, with regard to which Rabbi Meir says that the house remains pure? Accordingly, Rabbi Yosei is responding to Rabbi Meir and saying: Even if the neck of the dog is not the size of one cubic handbreadth, as long as the impure item inside the dog is located from under the lintel and toward the house, the house is impure because it overlies the impure item.
וּשְׁמַע מִינַּהּ: טוּמְאָה טְמוּנָה בּוֹקַעַת!
And therefore learn from it that Rabbi Yosei holds that a hidden source of impurity breaks through and ascends, contrary to Rabbi Yosei’s opinion as understood from his previous statement.
אָמַר רָבָא: רוֹאִין אֶת חֲלַל הַטּוּמְאָה קָתָנֵי, וְרַבִּי יוֹסֵי בְּתַרְתֵּי פְּלִיג, וְקָאָמַר לֵיהּ לְרַבִּי מֵאִיר: דְּקָאָמְרַתְּ כִּי יֵשׁ בְּצַוָּארוֹ פּוֹתֵחַ טֶפַח מֵבִיא אֶת הַטּוּמְאָה – אֲנַן בָּתַר חֲלָלַהּ אָזְלִינַן.
Rava said: Rabbi Yosei holds that a hidden source of impurity does not break through and ascend. As for that which Rabbi Yosei teaches: One looks whether the impure item inside the dog is located opposite the lintel and toward the inside of the house, Rabbi Yosei actually teaches: One looks at the empty space adjacent to the source of impurity. And Rabbi Yosei disagrees with Rabbi Meir with regard to two matters, and says to Rabbi Meir: As for that which you say that if there is the width of one cubic handbreadth in the neck of the dog, it imports the impurity into the house, that is not so. Rather, we follow the measure of the empty space, i.e., the neck of the dog imports impurity into the house only if it contains a cubic handbreadth of space in addition to the thickness of the flesh of the neck itself.
וּדְקָא אָמְרַתְּ הַבַּיִת כּוּלּוֹ טָמֵא – מִכְּנֶגֶד הַשְּׁקוֹף וְלִפְנִים הַבַּיִת טָמֵא, מִכְּנֶגֶד הַשְּׁקוֹף וְלַחוּץ הַבַּיִת טָהוֹר.
And with regard to that which you say that even if the dog is located on the outer portion of the threshold of the house, the entire house is impure, that is not so. Rather, if the impurity inside the dog is located anywhere from opposite the lintel and toward the inside of the house, the house is impure. If the impurity inside the dog is located anywhere from opposite the lintel and toward the outside of the house, the house remains pure.
רַב אַחָא בְּרֵיהּ דְּרָבָא מַתְנֵי לַהּ בְּהֶדְיָא: רַבִּי יוֹסֵי אוֹמֵר: רוֹאִין אֶת חֲלַל הַטּוּמְאָה.
Rav Aḥa, son of Rava, teaches that Rava’s explanation is explicit in the mishna itself, as follows: Rabbi Yosei says: One looks at the empty space adjacent to the source of impurity.
וּמַאן תַּנָּא דִּפְלִיג עֲלֵיהּ? רַבִּי שִׁמְעוֹן הוּא, דְּתַנְיָא: רַבִּי שִׁמְעוֹן אוֹמֵר:
§Previously the Gemara established that Rabbi Yosei holds that with regard to the halakhot of impurity, overlying is referred to as touching, as the transmission of impurity via contact and via overlying are considered one category. But the mishna (Oholot 3:1) cited earlier (125b) states that in the case of one who touches half an olive-bulk of flesh of a corpse, if a tent simultaneously overlies him and another half an olive-bulk of flesh he remains pure. Evidently, there is a tanna who disagrees with Rabbi Yosei and holds that these two methods of transmitting impurity are not the same category. The Gemara asks: Who is the tanna who disagrees with Rabbi Yosei? The Gemara answers: It is Rabbi Shimon, as it is taught in a baraita: Rabbi Shimon says:
שָׁלֹשׁ טוּמְאוֹת פּוֹרְשׁוֹת מִן הַמֵּת, שְׁתַּיִם בְּכׇל אַחַת וּשְׁלִישִׁית אֵין בָּהֶן, וְאֵלּוּ הֵן: מְלֹא תַרְוָוד רָקָב, וְעֶצֶם כִּשְׂעוֹרָה, וְגוֹלֵל וְדוֹפֵק.
Parts of a corpse that impart impurity include an olive-bulk of flesh, a complete limb, the majority of a corpse’s bones, and the majority of the essential bones of its skeleton, namely, its legs, spine, and ribs. All of these impart impurity via contact, carrying, and in a tent. There are also three sources of impurity that derive from a corpse, each one of which imparts impurity in two ways but does not impart impurity in a third way. And they are the following: A full ladle of dust from a corpse, and a bone the size of a barley grain, and a grave cover [golel] and a grave wall [dofek] upon which the cover rests.
מְלֹא תַרְוָוד רָקָב – מְטַמֵּא בְּמַשָּׂא וּבְאֹהֶל, וְאֵינוֹ מְטַמֵּא בְּמַגָּע, וְהֵיכָן מַגָּעוֹ? עִם אַחַת מֵהֶן.
A full ladle of dust imparts impurity via carrying and in a tent, but it does not impart impurity via contact, as it is impossible for one to touch all of the particles of dust simultaneously. And where among these sources of impurity is the imparting of impurity via contact applicable? It is applicable with one of those other two sources of impurity, i.e., a bone the size of a barley grain and the cover or wall of a grave.
עֶצֶם כִּשְׂעוֹרָה – מְטַמֵּא בְּמַשָּׂא וּבְמַגָּע, וְאֵינוֹ מְטַמֵּא בְּאֹהֶל, וְהֵיכָן אׇהֳלוֹ? עִם אַחַת מֵהֶן.
A bone the size of a barley grain imparts impurity via carrying and contact, but it does not impart impurity in a tent. This halakha was transmitted to Moses from Sinai. And where among these sources of impurity is impurity imparted in a tent? It is with one of those other two sources of impurity.
הַגּוֹלֵל וְדוֹפֵק – מְטַמֵּא בְּמַגָּע וּבְאֹהֶל, וְאֵינוֹ מְטַמֵּא בְּמַשָּׂא, וְהֵיכָן מַשָּׂאוֹ? עִם אֶחָד מֵהֶן.
A grave cover and a grave wall impart impurity via contact and in a tent, but they do not impart impurity via carrying. This halakha too was transmitted to Moses from Sinai. And where among these sources of impurity is impurity transmitted via carrying? It is with one of those other two sources of impurity. It may be inferred from Rabbi Shimon’s statement that a full ladle of dust imparts impurity in a tent but not via contact that he disagrees with Rabbi Yosei and holds that overlying is not the same category as touching.
קוּלִית נְבֵלָה וְקוּלִית הַשֶּׁרֶץ וְכוּ׳. תָּנוּ רַבָּנַן: ״בְּנִבְלָתָהּ״ – וְלֹא בְּקוּלִית סְתוּמָה.
§The mishna teaches: With regard to the thigh bone of an unslaughtered carcass and the thigh bone of a creeping animal, one who touches them when they are sealed remains ritually pure, because the bone itself does not impart impurity. With regard to this topic, the Sages taught in a baraita: The verse states: “One who touches the carcass thereof shall be impure until the evening” (Leviticus 11:39). The word “carcass” indicates that one who touches the carcass is impure, but one who touches a sealed thigh bone is not.
יָכוֹל אֲפִילּוּ נִיקְּבָה? תַּלְמוּד לוֹמַר ״הַנּוֹגֵעַ … יִטְמָא״, אֶת שֶׁאֶפְשָׁר לִיגַּע – טָמֵא, וְאֶת שֶׁאִי אֶפְשָׁר לִיגַּע – טָהוֹר.
One might have thought that even one who touches a perforated thigh bone remains pure. Therefore, the verse states: “One who touches the carcass thereof [benivlatah] shall be impure,” indicating that one who touches a part of the animal through which it is possible to touch the flesh, which has the halakhic status of an unslaughtered carcass [neveila], is impure, but one who touches a part of the animal through which it is impossible to touch the flesh remains pure. Therefore, one who touches a protective layer such as the outside of a sealed thigh bone does not become impure, as it is impossible to touch the marrow.
אֲמַר לֵיהּ רַבִּי זֵירָא לְאַבָּיֵי: אֶלָּא מֵעַתָּה, בְּהֵמָה בְּעוֹרָהּ לֹא תְּטַמֵּא? פּוֹק חֲזִי כַּמָּה נְקָבִים יֵשׁ בָּהּ!
Rabbi Zeira said to Abaye: If that is so, that one who touches the protective layer of a carcass via which it is impossible to touch the flesh of the carcass itself does not become impure, an animal still in its hide should not impart impurity, as one can touch the hide, which constitutes a protective layer, but not the flesh. Abaye answered: Go out and see how many orifices there are in the body of an animal via which one can touch the flesh, e.g., the eyes, the nostrils, and the mouth.
אֲמַר לֵיהּ רַב פָּפָּא לְרָבָא: אֶלָּא מֵעַתָּה, כּוּלְיָא בְּחֶלְבָּהּ לֹא תְּטַמֵּא? תָּא חֲזִי כַּמָּה חוּטִין נִמְשָׁכִין הֵימֶנָּה.
Similarly, Rav Pappa said to Rava: If that is so, that one who touches the protective layer of a carcass via which it is impossible to touch the flesh of the carcass itself does not become impure, the kidney of a carcass that is completely covered in its fat should not impart impurity via contact. Rava answered: Come and see how many sinews emerge from the kidney that one is able to touch.
בָּעֵי רַב אוֹשַׁעְיָא: חִישֵּׁב עָלֶיהָ לְנוֹקְבָהּ וְלֹא נִיקְּבָה, מַהוּ? מְחוּסַּר נְקִיבָה כִּמְחוּסַּר מַעֲשֶׂה דָּמֵי, אוֹ לָא?
§The mishna taught that the halakha distinguishes between a sealed and a perforated thigh bone of a carcass or a creeping animal. With regard to this topic, Rav Oshaya raises a dilemma: What is the halakha if one intended to perforate the thigh bone but did not yet perforate it? This is the dilemma: Is a thigh bone lacking perforation considered to be lacking the necessary action for it to impart impurity, and it therefore retains its status as a sealed thigh bone, or not?
הֲדַר פַּשְׁטַהּ: מְחוּסַּר נְקִיבָה לָאו כִּמְחוּסַּר מַעֲשֶׂה דָּמֵי.
Rabbi Oshaya then resolves the dilemma: A thigh bone lacking perforation is not considered to be lacking the necessary action for it to impart impurity. If one intends to perforate it, it imparts impurity immediately.
מַתְנִי׳ בֵּיצַת הַשֶּׁרֶץ הַמְרוּקֶּמֶת טְהוֹרָה, נִיקְּבָה כׇּל שֶׁהוּא – טָמֵא. עַכְבָּר שֶׁחֶצְיוֹ בָּשָׂר וְחֶצְיוֹ אֲדָמָה – הַנּוֹגֵעַ בַּבָּשָׂר טָמֵא, בָּאֲדָמָה טָהוֹר. רַבִּי יְהוּדָה אוֹמֵר: אַף הַנּוֹגֵעַ בָּאֲדָמָה שֶׁכְּנֶגֶד הַבָּשָׂר טָמֵא.
MISHNA: The egg of a creeping animal in which tissue of an embryo developed and one who comes into contact with the egg are ritually pure, as the impure creeping animal is hermetically sealed. But if one perforated the egg with a hole of any size, one who comes in contact with the egg is ritually impure. In the case of a mouse that grows from the ground and is half-flesh half-earth, one who touches the half that is flesh is impure; one who touches the half that is earth is pure. Rabbi Yehuda says: Even one who touches the half that is earth where it is adjacent to the flesh is ritually impure.
גְּמָ׳ תָּנוּ רַבָּנַן: ״הַטְּמֵאִים״ – לְרַבּוֹת בֵּיצַת הַשֶּׁרֶץ וְקוּלִית הַשֶּׁרֶץ.
GEMARA: The mishna states that in the case of an egg of a creeping animal in which tissue of an embryo developed, if it is perforated then one who touches it is ritually impure. With regard to this matter the Sages taught in a baraita: The verse states: “These are the impure ones to you among all that creep; whoever touches them when they are dead shall be impure until the evening” (Leviticus 11:31). The term “the impure ones” is interpreted as including the egg of a creeping animal and the thigh bone of a creeping animal in the category of sources of impurity.
יָכוֹל אֲפִילּוּ לֹא רִיקְּמָה? תַּלְמוּד לוֹמַר ״הַשֶּׁרֶץ״ – מָה שֶׁרֶץ שֶׁרִקֵּם, אַף בֵּיצַת הַשֶּׁרֶץ שֶׁרִקְּמָה.
One might have thought that even an egg in which tissue of an embryo has not developed imparts impurity. Therefore, the verse states: “That creep,” indicating that just as a creeping animal has developed tissue, so too only the egg of a creeping animal in which tissue of an embryo has developed imparts impurity.
יָכוֹל אֲפִילּוּ לֹא נִיקְּבוּ? תַּלְמוּד לוֹמַר ״הַנּוֹגֵעַ … יִטְמָא״, אֶת שֶׁאֶפְשָׁר לִיגַּע – טָמֵא, וְאֶת שֶׁאִי אֶפְשָׁר לִיגַּע – טָהוֹר.
One might have thought that in the case of an egg in which tissue of an embryo has developed, it imparts impurity even if it was not perforated. Therefore, the verse states: “Whoever touches them when they are dead shall be impure,” indicating that when it is possible to touch the flesh, contact renders one impure; but when it is impossible to touch the flesh, one remains pure.
וְכַמָּה נְקִיבָתָהּ? כְּחוּט הַשַּׂעֲרָה, שֶׁאֶפְשָׁר לִיגַּע כְּחוּט הַשַּׂעֲרָה.
And how large must its perforation be to render one touching the egg or thigh bone impure? Its width must be the size of a strand of hair, as it is possible for one to touch the inside of an egg or thigh bone with a strand of his hair.
עַכְבָּר שֶׁחֶצְיוֹ [וְכוּ׳]. אָמַר רַבִּי יְהוֹשֻׁעַ בֶּן לֵוִי: וְהוּא שֶׁהִשְׁרִיץ עַל פְּנֵי כּוּלּוֹ. אִיכָּא דְּמַתְנֵי לַהּ אַסֵּיפָא – רַבִּי יְהוּדָה אוֹמֵר: אַף הַנּוֹגֵעַ בָּאֲדָמָה שֶׁכְּנֶגֶד בָּשָׂר טָמֵא, אָמַר רַבִּי יְהוֹשֻׁעַ בֶּן לֵוִי: וְהוּא שֶׁהִשְׁרִיץ עַל פְּנֵי כּוּלּוֹ.
§The mishna teaches: In the case of a mouse that grows from the ground and is half-flesh half-earth, one who touches the half that is flesh is impure. Rabbi Yehoshua ben Levi says in this regard: One becomes impure in such a case only if the flesh of the mouse has developed along the entire length of the mouse, from head to foot. Some teach the statement of Rabbi Yehoshua ben Levi with regard to the latter clause of the mishna: Rabbi Yehuda says: Even one who touches the half that is earth where it is adjacent to the flesh is ritually impure. Rabbi Yehoshua ben Levi says: One becomes impure in such a case only if the flesh of the mouse has developed along the entire length of the mouse.
מַאן דְּמַתְנֵי לַהּ אַרֵישָׁא, כׇּל שֶׁכֵּן אַסֵּיפָא, וּמַאן דְּמַתְנֵי לַהּ אַסֵּיפָא – אֲבָל רֵישָׁא, אַף עַל גַּב דְּלָא הִשְׁרִיץ.
The one who teaches the statement of Rabbi Yehoshua ben Levi with regard to the first clause of the mishna, all the more so he teaches this same halakha with regard to the latter clause of the mishna. But the one who teaches the statement of Rabbi Yehoshua ben Levi with regard to the latter clause of the mishna holds that it applies only to that clause, with regard to one who touches the half that is earth where it is adjacent to the flesh according to Rabbi Yehuda. But according to the opinion of the first tanna, stated in the first clause of the mishna, even if the flesh of the mouse has not developed along the entire length of the mouse, one who touches the half of the mouse that is flesh is impure.
תָּנוּ רַבָּנַן: מִתּוֹךְ שֶׁנֶּאֱמַר ״עַכְבָּר״, שׁוֹמֵעַ אֲנִי אֲפִילּוּ עַכְבָּר שֶׁבַּיָּם, שֶׁשְּׁמוֹ עַכְבָּר. וְדִין הוּא: טִימֵּא בְּחוּלְדָּה וְטִימֵּא בְּעַכְבָּר, מָה חוּלְדָּה מִין הַגָּדֵל עַל הָאָרֶץ, אַף עַכְבָּר מִין הַגָּדֵל עַל הָאָרֶץ.
§The Sages taught in a baraita concerning the following verse: “And these are they which are impure to you among the creeping animals that creep upon the earth: The weasel, and the mouse, and the great lizard after its kinds” (Leviticus 11:29). Since “mouse” is stated among the creeping animals that impart impurity, I would derive that even a sea mouse, i.e., a sea creature that has an appearance similar to a mouse, imparts impurity because its name is also mouse. But ostensibly, the opposite conclusion could be derived through logical inference: The verse deems a weasel impure and deems a mouse impure. Therefore, just as a weasel is a species that grows on land, so too the mouse to which the verse is referring is a species that grows on land; a sea mouse does not impart impurity.
אוֹ כְּלָךְ לְדֶרֶךְ זוֹ: טִימֵּא בְּחוּלְדָּה וְטִימֵּא בְּעַכְבָּר, מָה חוּלְדָּה כֹּל שֶׁשְּׁמָהּ ״חוּלְדָּה״, אַף עַכְבָּר כֹּל שֶׁשְּׁמוֹ ״עַכְבָּר״, אֲפִילּוּ עַכְבָּר שֶׁבַּיָּם שֶׁשְּׁמוֹ ״עַכְבָּר״. תַּלְמוּד לוֹמַר ״עַל הָאָרֶץ״.
Or, perhaps go this way: The verse deems a weasel impure and deems a mouse impure; accordingly, just as “weasel” is referring to any animal whose name is weasel, so too, “mouse” is referring to any animal whose name is mouse, even a sea mouse, as its name is also mouse. Therefore, the verse states: “Upon the earth,” indicating that a land mouse imparts impurity, but a sea mouse does not.
אִי ״עַל הָאָרֶץ״, יָכוֹל עַל הָאָרֶץ – יְטַמֵּא, יָרַד לְיָם – לֹא יְטַמֵּא,
If this halakha is derived only from the phrase “upon the earth,” one might have thought that the verse means that any mouse, whether a land mouse or a sea mouse, imparts impurity when it is upon the earth, but if it descended to the sea it does not impart impurity.

Meet the diverse women learning Gemara at Hadran and hear their stories.
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!

I am a Reform rabbi and took Talmud courses in rabbinical school, but I knew there was so much more to learn. It felt inauthentic to serve as a rabbi without having read the entire Talmud, so when the opportunity arose to start Daf Yomi in 2020, I dove in! Thanks to Hadran, Daf Yomi has enriched my understanding of rabbinic Judaism and deepened my love of Jewish text & tradition. Todah rabbah!

I started learning at the beginning of this cycle more than 2 years ago, and I have not missed a day or a daf. It’s been challenging and enlightening and even mind-numbing at times, but the learning and the shared experience have all been worth it. If you are open to it, there’s no telling what might come into your life.

A few years back, after reading Ilana Kurshan’s book, “If All The Seas Were Ink,” I began pondering the crazy, outlandish idea of beginning the Daf Yomi cycle. Beginning in December, 2019, a month before the previous cycle ended, I “auditioned” 30 different podcasts in 30 days, and ultimately chose to take the plunge with Hadran and Rabbanit Michelle. Such joy!

Shortly after the death of my father, David Malik z”l, I made the commitment to Daf Yomi. While riding to Ben Gurion airport in January, Siyum HaShas was playing on the radio; that was the nudge I needed to get started. The “everyday-ness” of the Daf has been a meaningful spiritual practice, especial after COVID began & I was temporarily unable to say Kaddish at daily in-person minyanim.

I started learning Daf in Jan 2020 with Brachot b/c I had never seen the Jewish people united around something so positive, and I wanted to be a part of it. Also, I wanted to broaden my background in Torah Shebal Peh- Maayanot gave me a great gemara education, but I knew that I could hold a conversation in most parts of tanach but almost no TSB. I’m so thankful for Daf and have gained immensely.

I learned Mishnayot more than twenty years ago and started with Gemara much later in life. Although I never managed to learn Daf Yomi consistently, I am learning since some years Gemara in depth and with much joy. Since last year I am studying at the International Halakha Scholars Program at the WIHL. I often listen to Rabbanit Farbers Gemara shiurim to understand better a specific sugyiah. I am grateful for the help and inspiration!

I started learning on January 5, 2020. When I complete the 7+ year cycle I will be 70 years old. I had been intimidated by those who said that I needed to study Talmud in a traditional way with a chevruta, but I decided the learning was more important to me than the method. Thankful for Daf Yomi for Women helping me catch up when I fall behind, and also being able to celebrate with each Siyum!

I’ve been learning since January 2020, and in June I started drawing a phrase from each daf. Sometimes it’s easy (e.g. plants), sometimes it’s very hard (e.g. korbanot), and sometimes it’s loads of fun (e.g. bird racing) to find something to draw. I upload my pictures from each masechet to #DafYomiArt. I am enjoying every step of the journey.

When I began the previous cycle, I promised myself that if I stuck with it, I would reward myself with a trip to Israel. Little did I know that the trip would involve attending the first ever women’s siyum and being inspired by so many learners. I am now over 2 years into my second cycle and being part of this large, diverse, fascinating learning family has enhanced my learning exponentially.

I had dreamed of doing daf yomi since I had my first serious Talmud class 18 years ago at Pardes with Rahel Berkovitz, and then a couple of summers with Leah Rosenthal. There is no way I would be able to do it without another wonderful teacher, Michelle, and the Hadran organization. I wake up and am excited to start each day with the next daf.

My curiosity was peaked after seeing posts about the end of the last cycle. I am always looking for opportunities to increase my Jewish literacy & I am someone that is drawn to habit and consistency. Dinnertime includes a “Guess what I learned on the daf” segment for my husband and 18 year old twins. I also love the feelings of connection with my colleagues who are also learning.

After enthusing to my friend Ruth Kahan about how much I had enjoyed remote Jewish learning during the earlier part of the pandemic, she challenged me to join her in learning the daf yomi cycle. I had always wanted to do daf yomi but now had no excuse. The beginning was particularly hard as I had never studied Talmud but has become easier, as I have gained some familiarity with it.

I started to listen to Michelle’s podcasts four years ago. The minute I started I was hooked. I’m so excited to learn the entire Talmud, and think I will continue always. I chose the quote “while a woman is engaged in conversation she also holds the spindle”. (Megillah 14b). It reminds me of all of the amazing women I learn with every day who multi-task, think ahead and accomplish so much.

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.

With Rabbanit Dr. Naomi Cohen in the Women’s Talmud class, over 30 years ago. It was a “known” class and it was accepted, because of who taught. Since then I have also studied with Avigail Gross-Gelman and Dr. Gabriel Hazut for about a year). Years ago, in a shiur in my shul, I did know about Persians doing 3 things with their clothes on. They opened the shiur to woman after that!

I start learning Daf Yomi in January 2020. The daily learning with Rabbanit Michelle has kept me grounded in this very uncertain time. Despite everything going on – the Pandemic, my personal life, climate change, war, etc… I know I can count on Hadran’s podcast to bring a smile to my face.

I began to learn this cycle of Daf Yomi after my husband passed away 2 1/2 years ago. It seemed a good way to connect to him. Even though I don’t know whether he would have encouraged women learning Gemara, it would have opened wonderful conversations. It also gives me more depth for understanding my frum children and grandchildren. Thank you Hadran and Rabbanit Michelle Farber!!

וְתָנֵי עֲלַהּ: רַבִּי יוֹסֵי מְטַהֵר. אַהֵיָיא? אִילֵּימָא אַסֵּיפָא – תַּנָּא קַמָּא נָמֵי טַהוֹרֵי קָא מְטַהַר!
And it is taught with regard to that halakha in the mishna that Rabbi Yosei deems it pure. To which halakha in the mishna is this referring? If we say that it is referring to the latter clause of the mishna, which discusses a chest placed in the entrance of the house, the first tanna also deems it pure in that case.
אֶלָּא, דְּקָאָמַר תַּנָּא קַמָּא: טוּמְאָה בְּתוֹכָהּ – הַבַּיִת טָמֵא, אִי מִשּׁוּם דְּדֶרֶךְ טוּמְאָה לָצֵאת, וְאִי מִשּׁוּם דְּטוּמְאָה טְמוּנָה בּוֹקַעַת. וְקָאָמַר לֵיהּ רַבִּי יוֹסֵי: וּדְקָאָמְרַתְּ דֶּרֶךְ טוּמְאָה לָצֵאת – יָכוֹל הוּא לְהוֹצִיאָהּ לַחֲצָאִין אוֹ לְשׂוֹרְפָהּ בִּמְקוֹמָהּ, וּדְקָאָמְרַתְּ טוּמְאָה טְמוּנָה בּוֹקַעַת – טוּמְאָה טְמוּנָה אֵינָהּ בּוֹקַעַת.
Rather, it is clear that the first tanna says that if a source of impurity is inside the compartment of a chest that is inside the house, the house is impure, either because it is typical for a source of impurity to exit its location, or because he holds that a hidden source of impurity breaks through and ascends. And Rabbi Yosei disagrees and says to him: With regard to that which you say that it is typical for a source of impurity to exit its location, it is not necessarily so. One can remove the impure item in halves or burn it in its place inside the compartment. And with regard to that which you say that a hidden source of impurity breaks through and ascends, a hidden source of impurity does not break through. Consequently, Rabbi Yosei must hold that a hidden source of impurity does not break through and ascend.
וְרָמֵי דְּרַבִּי יוֹסֵי אַדְּרַבִּי יוֹסֵי.
§Based on the previous statement of Rabbi Yosei, the Gemara established that Rabbi Yosei holds that a hidden source of impurity does not break through and ascend. And the Gemara raises a contradiction between that previous statement of Rabbi Yosei and another statement of Rabbi Yosei.
דִּתְנַן: הַכֶּלֶב שֶׁאָכַל בָּשָׂר מֵת, וּמֵת הַכֶּלֶב, וּמוּטָּל עַל הָאִסְקוּפָּה – רַבִּי מֵאִיר אוֹמֵר: אִם יֵשׁ בְּצַוָּארוֹ פּוֹתֵחַ טֶפַח – מֵבִיא אֶת הַטּוּמְאָה, וְאִם לָאו – אֵינוֹ מֵבִיא אֶת הַטּוּמְאָה.
As we learned in a mishna (Oholot 11:7): In the case of a dog that ate the flesh of a corpse, and the dog then died and is lying on the threshold in such a manner that its neck and mouth are facing toward the inside of the house, Rabbi Meir says: If there is an opening the size of one cubic handbreadth inside the neck of the dog, i.e., the neck itself constitutes this measure, the dog imports impurity into the house because the upper portion of the dog’s body overlies the impure item inside the dog and the impurity is transmitted through the neck and mouth of the dog into the house. But if there is not such a large cavity in the neck of the dog, then there is no halakha of a tent, and the dog does not import the impurity into the house.
רַבִּי יוֹסֵי אוֹמֵר: רוֹאִין מִכְּנֶגֶד הַשָּׁקוֹף וְלִפְנִים – הַבַּיִת טָמֵא, מִכְּנֶגֶד הַשְּׁקוֹף וְלַחוּץ – הַבַּיִת טָהוֹר.
Rabbi Yosei says: One looks to determine exactly where on the threshold the dog is located. If the impure item inside the dog is located anywhere from opposite, i.e., under, the lintel and toward the inside of the house, the house is impure. If the dog is located anywhere from opposite the lintel and toward the outside of the house, the house remains pure.
רַבִּי אֶלְעָזָר אוֹמֵר: פִּיו לִפְנִים הַבַּיִת – טָהוֹר, פִּיו לַחוּץ הַבַּיִת – טָמֵא, מִפְּנֵי שֶׁטּוּמְאָה יוֹצְאָה דֶּרֶךְ שׁוּלָיו.
Rabbi Elazar says: One must determine the exact manner in which the dog is lying on the threshold. If its mouth is located inside the house, but its rear is located outside the house, the house remains pure. If its mouth is located outside the house but its rear is located inside the house, the house is impure. This is because the source of impurity exits the dog’s body through its edge, i.e., its rear.
רַבִּי יְהוּדָה בֶּן בְּתִירָא אוֹמֵר: בֵּין כָּךְ וּבֵין כָּךְ, הַבַּיִת טָמֵא.
Rabbi Yehuda ben Beteira says: In both this case and that case, i.e., whether the dog is lying such that its mouth is inside the house or outside the house, the house is impure. The reason is that the impure item can exit through either the mouth or the rear.
מַאי לָאו, אַאֵין בְּצַוָּארוֹ פּוֹתֵחַ טֶפַח קָאֵי רַבִּי יוֹסֵי?
The Gemara analyzes the statement of Rabbi Yosei that if the dog is located anywhere from under the lintel and toward the inside of the house, the house is impure. What, is the statement of Rabbi Yosei not referring to a case where there is not an opening the size of one cubic handbreadth inside the dog’s neck, with regard to which Rabbi Meir says that the house remains pure? Accordingly, Rabbi Yosei is responding to Rabbi Meir and saying: Even if the neck of the dog is not the size of one cubic handbreadth, as long as the impure item inside the dog is located from under the lintel and toward the house, the house is impure because it overlies the impure item.
וּשְׁמַע מִינַּהּ: טוּמְאָה טְמוּנָה בּוֹקַעַת!
And therefore learn from it that Rabbi Yosei holds that a hidden source of impurity breaks through and ascends, contrary to Rabbi Yosei’s opinion as understood from his previous statement.
אָמַר רָבָא: רוֹאִין אֶת חֲלַל הַטּוּמְאָה קָתָנֵי, וְרַבִּי יוֹסֵי בְּתַרְתֵּי פְּלִיג, וְקָאָמַר לֵיהּ לְרַבִּי מֵאִיר: דְּקָאָמְרַתְּ כִּי יֵשׁ בְּצַוָּארוֹ פּוֹתֵחַ טֶפַח מֵבִיא אֶת הַטּוּמְאָה – אֲנַן בָּתַר חֲלָלַהּ אָזְלִינַן.
Rava said: Rabbi Yosei holds that a hidden source of impurity does not break through and ascend. As for that which Rabbi Yosei teaches: One looks whether the impure item inside the dog is located opposite the lintel and toward the inside of the house, Rabbi Yosei actually teaches: One looks at the empty space adjacent to the source of impurity. And Rabbi Yosei disagrees with Rabbi Meir with regard to two matters, and says to Rabbi Meir: As for that which you say that if there is the width of one cubic handbreadth in the neck of the dog, it imports the impurity into the house, that is not so. Rather, we follow the measure of the empty space, i.e., the neck of the dog imports impurity into the house only if it contains a cubic handbreadth of space in addition to the thickness of the flesh of the neck itself.
וּדְקָא אָמְרַתְּ הַבַּיִת כּוּלּוֹ טָמֵא – מִכְּנֶגֶד הַשְּׁקוֹף וְלִפְנִים הַבַּיִת טָמֵא, מִכְּנֶגֶד הַשְּׁקוֹף וְלַחוּץ הַבַּיִת טָהוֹר.
And with regard to that which you say that even if the dog is located on the outer portion of the threshold of the house, the entire house is impure, that is not so. Rather, if the impurity inside the dog is located anywhere from opposite the lintel and toward the inside of the house, the house is impure. If the impurity inside the dog is located anywhere from opposite the lintel and toward the outside of the house, the house remains pure.
רַב אַחָא בְּרֵיהּ דְּרָבָא מַתְנֵי לַהּ בְּהֶדְיָא: רַבִּי יוֹסֵי אוֹמֵר: רוֹאִין אֶת חֲלַל הַטּוּמְאָה.
Rav Aḥa, son of Rava, teaches that Rava’s explanation is explicit in the mishna itself, as follows: Rabbi Yosei says: One looks at the empty space adjacent to the source of impurity.
וּמַאן תַּנָּא דִּפְלִיג עֲלֵיהּ? רַבִּי שִׁמְעוֹן הוּא, דְּתַנְיָא: רַבִּי שִׁמְעוֹן אוֹמֵר:
§Previously the Gemara established that Rabbi Yosei holds that with regard to the halakhot of impurity, overlying is referred to as touching, as the transmission of impurity via contact and via overlying are considered one category. But the mishna (Oholot 3:1) cited earlier (125b) states that in the case of one who touches half an olive-bulk of flesh of a corpse, if a tent simultaneously overlies him and another half an olive-bulk of flesh he remains pure. Evidently, there is a tanna who disagrees with Rabbi Yosei and holds that these two methods of transmitting impurity are not the same category. The Gemara asks: Who is the tanna who disagrees with Rabbi Yosei? The Gemara answers: It is Rabbi Shimon, as it is taught in a baraita: Rabbi Shimon says:
שָׁלֹשׁ טוּמְאוֹת פּוֹרְשׁוֹת מִן הַמֵּת, שְׁתַּיִם בְּכׇל אַחַת וּשְׁלִישִׁית אֵין בָּהֶן, וְאֵלּוּ הֵן: מְלֹא תַרְוָוד רָקָב, וְעֶצֶם כִּשְׂעוֹרָה, וְגוֹלֵל וְדוֹפֵק.
Parts of a corpse that impart impurity include an olive-bulk of flesh, a complete limb, the majority of a corpse’s bones, and the majority of the essential bones of its skeleton, namely, its legs, spine, and ribs. All of these impart impurity via contact, carrying, and in a tent. There are also three sources of impurity that derive from a corpse, each one of which imparts impurity in two ways but does not impart impurity in a third way. And they are the following: A full ladle of dust from a corpse, and a bone the size of a barley grain, and a grave cover [golel] and a grave wall [dofek] upon which the cover rests.
מְלֹא תַרְוָוד רָקָב – מְטַמֵּא בְּמַשָּׂא וּבְאֹהֶל, וְאֵינוֹ מְטַמֵּא בְּמַגָּע, וְהֵיכָן מַגָּעוֹ? עִם אַחַת מֵהֶן.
A full ladle of dust imparts impurity via carrying and in a tent, but it does not impart impurity via contact, as it is impossible for one to touch all of the particles of dust simultaneously. And where among these sources of impurity is the imparting of impurity via contact applicable? It is applicable with one of those other two sources of impurity, i.e., a bone the size of a barley grain and the cover or wall of a grave.
עֶצֶם כִּשְׂעוֹרָה – מְטַמֵּא בְּמַשָּׂא וּבְמַגָּע, וְאֵינוֹ מְטַמֵּא בְּאֹהֶל, וְהֵיכָן אׇהֳלוֹ? עִם אַחַת מֵהֶן.
A bone the size of a barley grain imparts impurity via carrying and contact, but it does not impart impurity in a tent. This halakha was transmitted to Moses from Sinai. And where among these sources of impurity is impurity imparted in a tent? It is with one of those other two sources of impurity.
הַגּוֹלֵל וְדוֹפֵק – מְטַמֵּא בְּמַגָּע וּבְאֹהֶל, וְאֵינוֹ מְטַמֵּא בְּמַשָּׂא, וְהֵיכָן מַשָּׂאוֹ? עִם אֶחָד מֵהֶן.
A grave cover and a grave wall impart impurity via contact and in a tent, but they do not impart impurity via carrying. This halakha too was transmitted to Moses from Sinai. And where among these sources of impurity is impurity transmitted via carrying? It is with one of those other two sources of impurity. It may be inferred from Rabbi Shimon’s statement that a full ladle of dust imparts impurity in a tent but not via contact that he disagrees with Rabbi Yosei and holds that overlying is not the same category as touching.
קוּלִית נְבֵלָה וְקוּלִית הַשֶּׁרֶץ וְכוּ׳. תָּנוּ רַבָּנַן: ״בְּנִבְלָתָהּ״ – וְלֹא בְּקוּלִית סְתוּמָה.
§The mishna teaches: With regard to the thigh bone of an unslaughtered carcass and the thigh bone of a creeping animal, one who touches them when they are sealed remains ritually pure, because the bone itself does not impart impurity. With regard to this topic, the Sages taught in a baraita: The verse states: “One who touches the carcass thereof shall be impure until the evening” (Leviticus 11:39). The word “carcass” indicates that one who touches the carcass is impure, but one who touches a sealed thigh bone is not.
יָכוֹל אֲפִילּוּ נִיקְּבָה? תַּלְמוּד לוֹמַר ״הַנּוֹגֵעַ … יִטְמָא״, אֶת שֶׁאֶפְשָׁר לִיגַּע – טָמֵא, וְאֶת שֶׁאִי אֶפְשָׁר לִיגַּע – טָהוֹר.
One might have thought that even one who touches a perforated thigh bone remains pure. Therefore, the verse states: “One who touches the carcass thereof [benivlatah] shall be impure,” indicating that one who touches a part of the animal through which it is possible to touch the flesh, which has the halakhic status of an unslaughtered carcass [neveila], is impure, but one who touches a part of the animal through which it is impossible to touch the flesh remains pure. Therefore, one who touches a protective layer such as the outside of a sealed thigh bone does not become impure, as it is impossible to touch the marrow.
אֲמַר לֵיהּ רַבִּי זֵירָא לְאַבָּיֵי: אֶלָּא מֵעַתָּה, בְּהֵמָה בְּעוֹרָהּ לֹא תְּטַמֵּא? פּוֹק חֲזִי כַּמָּה נְקָבִים יֵשׁ בָּהּ!
Rabbi Zeira said to Abaye: If that is so, that one who touches the protective layer of a carcass via which it is impossible to touch the flesh of the carcass itself does not become impure, an animal still in its hide should not impart impurity, as one can touch the hide, which constitutes a protective layer, but not the flesh. Abaye answered: Go out and see how many orifices there are in the body of an animal via which one can touch the flesh, e.g., the eyes, the nostrils, and the mouth.
אֲמַר לֵיהּ רַב פָּפָּא לְרָבָא: אֶלָּא מֵעַתָּה, כּוּלְיָא בְּחֶלְבָּהּ לֹא תְּטַמֵּא? תָּא חֲזִי כַּמָּה חוּטִין נִמְשָׁכִין הֵימֶנָּה.
Similarly, Rav Pappa said to Rava: If that is so, that one who touches the protective layer of a carcass via which it is impossible to touch the flesh of the carcass itself does not become impure, the kidney of a carcass that is completely covered in its fat should not impart impurity via contact. Rava answered: Come and see how many sinews emerge from the kidney that one is able to touch.
בָּעֵי רַב אוֹשַׁעְיָא: חִישֵּׁב עָלֶיהָ לְנוֹקְבָהּ וְלֹא נִיקְּבָה, מַהוּ? מְחוּסַּר נְקִיבָה כִּמְחוּסַּר מַעֲשֶׂה דָּמֵי, אוֹ לָא?
§The mishna taught that the halakha distinguishes between a sealed and a perforated thigh bone of a carcass or a creeping animal. With regard to this topic, Rav Oshaya raises a dilemma: What is the halakha if one intended to perforate the thigh bone but did not yet perforate it? This is the dilemma: Is a thigh bone lacking perforation considered to be lacking the necessary action for it to impart impurity, and it therefore retains its status as a sealed thigh bone, or not?
הֲדַר פַּשְׁטַהּ: מְחוּסַּר נְקִיבָה לָאו כִּמְחוּסַּר מַעֲשֶׂה דָּמֵי.
Rabbi Oshaya then resolves the dilemma: A thigh bone lacking perforation is not considered to be lacking the necessary action for it to impart impurity. If one intends to perforate it, it imparts impurity immediately.
מַתְנִי׳ בֵּיצַת הַשֶּׁרֶץ הַמְרוּקֶּמֶת טְהוֹרָה, נִיקְּבָה כׇּל שֶׁהוּא – טָמֵא. עַכְבָּר שֶׁחֶצְיוֹ בָּשָׂר וְחֶצְיוֹ אֲדָמָה – הַנּוֹגֵעַ בַּבָּשָׂר טָמֵא, בָּאֲדָמָה טָהוֹר. רַבִּי יְהוּדָה אוֹמֵר: אַף הַנּוֹגֵעַ בָּאֲדָמָה שֶׁכְּנֶגֶד הַבָּשָׂר טָמֵא.
MISHNA: The egg of a creeping animal in which tissue of an embryo developed and one who comes into contact with the egg are ritually pure, as the impure creeping animal is hermetically sealed. But if one perforated the egg with a hole of any size, one who comes in contact with the egg is ritually impure. In the case of a mouse that grows from the ground and is half-flesh half-earth, one who touches the half that is flesh is impure; one who touches the half that is earth is pure. Rabbi Yehuda says: Even one who touches the half that is earth where it is adjacent to the flesh is ritually impure.
גְּמָ׳ תָּנוּ רַבָּנַן: ״הַטְּמֵאִים״ – לְרַבּוֹת בֵּיצַת הַשֶּׁרֶץ וְקוּלִית הַשֶּׁרֶץ.
GEMARA: The mishna states that in the case of an egg of a creeping animal in which tissue of an embryo developed, if it is perforated then one who touches it is ritually impure. With regard to this matter the Sages taught in a baraita: The verse states: “These are the impure ones to you among all that creep; whoever touches them when they are dead shall be impure until the evening” (Leviticus 11:31). The term “the impure ones” is interpreted as including the egg of a creeping animal and the thigh bone of a creeping animal in the category of sources of impurity.
יָכוֹל אֲפִילּוּ לֹא רִיקְּמָה? תַּלְמוּד לוֹמַר ״הַשֶּׁרֶץ״ – מָה שֶׁרֶץ שֶׁרִקֵּם, אַף בֵּיצַת הַשֶּׁרֶץ שֶׁרִקְּמָה.
One might have thought that even an egg in which tissue of an embryo has not developed imparts impurity. Therefore, the verse states: “That creep,” indicating that just as a creeping animal has developed tissue, so too only the egg of a creeping animal in which tissue of an embryo has developed imparts impurity.
יָכוֹל אֲפִילּוּ לֹא נִיקְּבוּ? תַּלְמוּד לוֹמַר ״הַנּוֹגֵעַ … יִטְמָא״, אֶת שֶׁאֶפְשָׁר לִיגַּע – טָמֵא, וְאֶת שֶׁאִי אֶפְשָׁר לִיגַּע – טָהוֹר.
One might have thought that in the case of an egg in which tissue of an embryo has developed, it imparts impurity even if it was not perforated. Therefore, the verse states: “Whoever touches them when they are dead shall be impure,” indicating that when it is possible to touch the flesh, contact renders one impure; but when it is impossible to touch the flesh, one remains pure.
וְכַמָּה נְקִיבָתָהּ? כְּחוּט הַשַּׂעֲרָה, שֶׁאֶפְשָׁר לִיגַּע כְּחוּט הַשַּׂעֲרָה.
And how large must its perforation be to render one touching the egg or thigh bone impure? Its width must be the size of a strand of hair, as it is possible for one to touch the inside of an egg or thigh bone with a strand of his hair.
עַכְבָּר שֶׁחֶצְיוֹ [וְכוּ׳]. אָמַר רַבִּי יְהוֹשֻׁעַ בֶּן לֵוִי: וְהוּא שֶׁהִשְׁרִיץ עַל פְּנֵי כּוּלּוֹ. אִיכָּא דְּמַתְנֵי לַהּ אַסֵּיפָא – רַבִּי יְהוּדָה אוֹמֵר: אַף הַנּוֹגֵעַ בָּאֲדָמָה שֶׁכְּנֶגֶד בָּשָׂר טָמֵא, אָמַר רַבִּי יְהוֹשֻׁעַ בֶּן לֵוִי: וְהוּא שֶׁהִשְׁרִיץ עַל פְּנֵי כּוּלּוֹ.
§The mishna teaches: In the case of a mouse that grows from the ground and is half-flesh half-earth, one who touches the half that is flesh is impure. Rabbi Yehoshua ben Levi says in this regard: One becomes impure in such a case only if the flesh of the mouse has developed along the entire length of the mouse, from head to foot. Some teach the statement of Rabbi Yehoshua ben Levi with regard to the latter clause of the mishna: Rabbi Yehuda says: Even one who touches the half that is earth where it is adjacent to the flesh is ritually impure. Rabbi Yehoshua ben Levi says: One becomes impure in such a case only if the flesh of the mouse has developed along the entire length of the mouse.
מַאן דְּמַתְנֵי לַהּ אַרֵישָׁא, כׇּל שֶׁכֵּן אַסֵּיפָא, וּמַאן דְּמַתְנֵי לַהּ אַסֵּיפָא – אֲבָל רֵישָׁא, אַף עַל גַּב דְּלָא הִשְׁרִיץ.
The one who teaches the statement of Rabbi Yehoshua ben Levi with regard to the first clause of the mishna, all the more so he teaches this same halakha with regard to the latter clause of the mishna. But the one who teaches the statement of Rabbi Yehoshua ben Levi with regard to the latter clause of the mishna holds that it applies only to that clause, with regard to one who touches the half that is earth where it is adjacent to the flesh according to Rabbi Yehuda. But according to the opinion of the first tanna, stated in the first clause of the mishna, even if the flesh of the mouse has not developed along the entire length of the mouse, one who touches the half of the mouse that is flesh is impure.
תָּנוּ רַבָּנַן: מִתּוֹךְ שֶׁנֶּאֱמַר ״עַכְבָּר״, שׁוֹמֵעַ אֲנִי אֲפִילּוּ עַכְבָּר שֶׁבַּיָּם, שֶׁשְּׁמוֹ עַכְבָּר. וְדִין הוּא: טִימֵּא בְּחוּלְדָּה וְטִימֵּא בְּעַכְבָּר, מָה חוּלְדָּה מִין הַגָּדֵל עַל הָאָרֶץ, אַף עַכְבָּר מִין הַגָּדֵל עַל הָאָרֶץ.
§The Sages taught in a baraita concerning the following verse: “And these are they which are impure to you among the creeping animals that creep upon the earth: The weasel, and the mouse, and the great lizard after its kinds” (Leviticus 11:29). Since “mouse” is stated among the creeping animals that impart impurity, I would derive that even a sea mouse, i.e., a sea creature that has an appearance similar to a mouse, imparts impurity because its name is also mouse. But ostensibly, the opposite conclusion could be derived through logical inference: The verse deems a weasel impure and deems a mouse impure. Therefore, just as a weasel is a species that grows on land, so too the mouse to which the verse is referring is a species that grows on land; a sea mouse does not impart impurity.
אוֹ כְּלָךְ לְדֶרֶךְ זוֹ: טִימֵּא בְּחוּלְדָּה וְטִימֵּא בְּעַכְבָּר, מָה חוּלְדָּה כֹּל שֶׁשְּׁמָהּ ״חוּלְדָּה״, אַף עַכְבָּר כֹּל שֶׁשְּׁמוֹ ״עַכְבָּר״, אֲפִילּוּ עַכְבָּר שֶׁבַּיָּם שֶׁשְּׁמוֹ ״עַכְבָּר״. תַּלְמוּד לוֹמַר ״עַל הָאָרֶץ״.
Or, perhaps go this way: The verse deems a weasel impure and deems a mouse impure; accordingly, just as “weasel” is referring to any animal whose name is weasel, so too, “mouse” is referring to any animal whose name is mouse, even a sea mouse, as its name is also mouse. Therefore, the verse states: “Upon the earth,” indicating that a land mouse imparts impurity, but a sea mouse does not.
אִי ״עַל הָאָרֶץ״, יָכוֹל עַל הָאָרֶץ – יְטַמֵּא, יָרַד לְיָם – לֹא יְטַמֵּא,
If this halakha is derived only from the phrase “upon the earth,” one might have thought that the verse means that any mouse, whether a land mouse or a sea mouse, imparts impurity when it is upon the earth, but if it descended to the sea it does not impart impurity.
