The mishna says that dead animals can join together to get to a requisite amount and creeping creatures also. Is the topic of the mishna for eating or for transferring impurities or both? There are three different opinions. According to Rav the requisite amount for eating creeping creatures is an olive bulk – which is different from the amount required for impurities – a lentil bulk. The gemara questions this opinion from another source and tries to resolve the contradiction.

Meilah 16
לֹא שָׁנוּ אֶלָּא לְעִנְיַן טוּמְאָה, אֲבָל לְעִנְיַן אֲכִילָה – טְהוֹרִין בִּפְנֵי עַצְמָן, וּטְמֵאִים בִּפְנֵי עַצְמָן. וְלֵוִי אָמַר: אֲפִילּוּ לַאֲכִילָה נָמֵי מִצְטָרְפִין.
The mishna taught that all carcasses join together, which indicates that carcasses of non-kosher animals join together with carcasses of kosher animals, only with regard to ritual impurity. But with regard to the prohibition of eating animal carcasses, kosher animal carcasses are distinct, i.e., they join together only with other kosher animals, and non-kosher animal carcasses are likewise distinct. And Levi says: Even with regard to the prohibition of eating animal carcasses, kosher and non-kosher carcasses join together.
וְרַב אַסִּי אָמַר: טְהוֹרִים לְעַצְמָן וּטְמֵאִין לְעַצְמָן. אִיכָּא דְאָמְרִי: פְּלִיגָא אַדְּרַב, וְאִיכָּא דְאָמְרִי: לָא פְּלִיגָא.
And Rav Asi says: Kosher animal carcasses are distinct, and non-kosher animal carcasses are distinct. Since Rav Asi did not specify whether he is referring only to eating or also to ritual impurity, there are those who say that Rav Asi disagrees with the opinion of Rav, i.e., he interprets the mishna as referring to all carcasses of a similar kind, that is, from kosher animals on the one hand, and from non-kosher animals on the other hand. And there are those who say that Rav Asi does not disagree with the opinion of Rav, and concedes that kosher and non-kosher animal carcasses join together with regard to ritual impurity.
מֵיתִיבִי: מִיתַת פָּרָה, וְחַיֵּי גָמָל – אֵין מִצְטָרְפִין זֶה עִם זֶה. הָא מִיתַת שְׁנֵיהֶם – מִצְטָרְפִין, וְקַשְׁיָא לְרַב אַסִּי!
The Gemara raises an objection against the first explanation of the opinion of Rav Asi from a baraita: With regard to half an olive-bulk from the carcass of a dead cow and half an olive-bulk from the flesh of a live camel, they do not join together with one another. It can be inferred from here that if both of them are dead, they do join together. Rav can explain this baraita as referring to ritual impurity, but this poses a difficulty to Rav Asi.
אֵימָא: הָא חַיֵּי שְׁנֵיהֶם – מִצְטָרְפִין, וּמַנִּי – רַבִּי יְהוּדָה הִיא, דְּאָמַר: אֵבֶר מִן הַחַי נוֹהֵג בַּטְּמֵאָה.
The Gemara answers: One should say that the correct inference from the baraita is not that if both of them, the cow and the camel, are dead, then they join together. Rather, one should infer that if both of them are alive, they join together. And who is the tanna of the baraita? It is Rabbi Yehuda, who said: The prohibition of eating a limb from a living animal applies even to the limb of a non-kosher animal.
אֲבָל מִיתַת שְׁנֵיהֶם, מַאי? לָא מִצְטָרְפִי? אִם כֵּן, מַאי אִירְיָא דְּרָהֵיט וְתָנֵי ״מִיתַת פָּרָה וְחַיֵּי גָמָל״, הָא אֲפִילּוּ מִיתַת שְׁנֵיהֶם לָא מִצְטָרְפִי!
The Gemara raises a difficulty with this answer. But in that case, what is the halakha if both of them, the cow and the camel, are dead? Do they not join together? If so, why does the tanna run specifically to an extreme case and teach: Half an olive-bulk from the carcass of a dead cow and half an olive-bulk from the flesh of a live camel? After all, even if both of them are dead, they do not join together.
וְעוֹד, תַּנְיָא: חֲצִי זַיִת פָּרָה בְּחַיֶּיהָ וַחֲצִי זַיִת גָּמָל בְּמִיתָתָהּ – אֵין מִצְטָרְפִין. אֲבָל חֲצִי זַיִת מִפָּרָה וַחֲצִי זַיִת מִגָּמָל, בֵּין בְּחַיֶּיהָ בֵּין בְּמִיתָתָהּ – מִצְטָרְפִין. קַשְׁיָא רֵישָׁא אַסֵּיפָא! אֶלָּא לָאו שְׁמַע מִינַּהּ: מִיתַת שְׁנֵיהֶם – מִצְטָרְפִין!?
And furthermore, it is taught in a baraita: Half an olive-bulk from the flesh of a cow when it is alive and half an olive-bulk from the carcass of a camel when it is dead do not join together; but half an olive-bulk from a cow and half an olive-bulk from a camel, whether alive or dead, do join together. The first clause in the baraita is difficult as it is apparently contradicted by the latter clause. Rather, isn’t it correct to conclude from the baraita that if there is half an olive-bulk from each of the two of them when they are dead, they join together?
אָמַר לְךָ רַב אַסִּי: הַאי תַּנָּא סָבַר אִיסּוּר חָל עַל אִיסּוּר.
The Gemara answers: Rav Asi could have said to you that this tanna holds that a prohibition takes effect even where another prohibition already exists. He maintains that the prohibition of eating an animal carcass takes effect even with regard to the flesh of a non-kosher animal, which is already prohibited, and for this reason the two half olive-bulks join together, as the same prohibition against eating an animal carcass applies to both. By contrast, Rav Asi himself maintains that a prohibition does not take effect where another prohibition already exists, and therefore this baraita does not pose a difficulty to his opinion that the two do not combine.
אָמַר רַב יְהוּדָה, אָמַר רַב: אֲכִילַת שְׁרָצִים – לוֹקֶה עָלָיו בִּכְזַיִת. מַאי טַעְמָא? ׳אֲכִילָה׳ כְּתִיב בְּהוּ.
§ Rav Yehuda says that Rav says: With regard to eating creeping animals, one is flogged for eating an olive-bulk of them. What is the reason? It is because the term “eating” is written in the Torah with regard to them. The verse states: “And every creeping thing that swarms upon the earth is a detestable thing; it shall not be eaten” (Leviticus 11:41). The term “eating” is invariably referring to consuming an olive-bulk.
וְהָתָנֵי רַבִּי יוֹסֵי בַּר רַבִּי חֲנִינָא קַמֵּיהּ דְּרַבִּי יוֹחָנָן: ״וְהִבְדַּלְתֶּם בֵּין הַבְּהֵמָה הַטְּהֹרָה לַטְּמֵאָה וּבֵין הָעוֹף הַטָּמֵא לַטָּהֹר וְלֹא תְשַׁקְּצוּ אֶת נַפְשֹׁתֵיכֶם בַּבְּהֵמָה וּבָעוֹף וּבְכֹל אֲשֶׁר תִּרְמֹשׂ הָאֲדָמָה אֲשֶׁר הִבְדַּלְתִּי לָכֶם לְטַמֵּא״ – פָּתַח הַכָּתוּב בַּאֲכִילָה, וְסִיֵּים בְּטוּמְאָה.
The Gemara raises a difficulty. But didn’t Rabbi Yosei bar Rabbi Ḥanina teach the following baraita before Rabbi Yoḥanan: The verse states: “You shall separate between the kosher animal and the non-kosher, and between the non-kosher bird and the kosher; and you shall not make your souls detestable by animal, or by bird, or by anything that swarms on the ground, which I have set apart for you as impure” (Leviticus 20:25). The verse opens with eating creeping animals, in the phrase “You shall not make your souls detestable,” and it ends with the ritual impurity of creeping animals: “Which I have set apart for you as impure.”
מָה טוּמְאָה בְּכַעֲדָשָׁה, אַף אֲכִילָה בְּכַעֲדָשָׁה. וְקַלְּסֵיהּ רַבִּי יוֹחָנָן, וְקַשְׁיָא לִדְרַב!
The baraita explains: This teaches that just as the carcass of a creeping animal imparts ritual impurity through contact when it is the volume of a lentil-bulk, so too, one is liable for the prohibition of eating a creeping animal when it is the volume of a lentil-bulk. And Rabbi Yoḥanan praised [vekilseih] Rabbi Yosei bar Rabbi Ḥanina for citing this baraita. And this poses a difficulty to the opinion of Rav, who maintains that one is flogged only if he eats an olive-bulk of creeping animals.
לָא קַשְׁיָא: כָּאן – בְּמִיתָתָן, כָּאן – בְּחַיֵּיהֶן.
The Gemara answers: This is not difficult. Here, the baraita is referring to eating creeping animals when they are dead, at which stage they impart ritual impurity and one is liable for eating a lentil-bulk. By contrast, there, Rav is speaking about eating creeping animals when they are alive, which do not yet impart ritual impurity. For this reason one is flogged only if he eats an olive-bulk.
אֲמַר לֵיהּ אַבָּיֵי: וְהָא רַב אַמַּתְנִיתִין קָאֵי, וּמַתְנִיתִין ״כׇּל הַשְּׁרָצִים״ קָתָנֵי, אֲפִילּוּ בְּמִיתָתָן. לָאו דְּאִיכָּא פּוּרְתָּא מֵהַאי וּפוּרְתָּא מֵהַאי? אֲמַר לֵיהּ רַב יוֹסֵף: הָהִיא דִּיּוּקָא דִּילָךְ הוּא. רַב – שְׁמַעְתָּא בְּעָלְמָא קָאָמַר.
Abaye said to Rav Yosef: But in his statement Rav was referring to the mishna, and the mishna teaches: And all the creeping animals join together to constitute the requisite olive-bulk measure to render one who consumes it liable to receive lashes. This indicates that this halakha applies even when they are dead. Is the mishna not referring to a case where there is a bit of this live creeping animal and a bit of that carcass of a creeping animal, which together combine to amount to an olive-bulk? Rav Yosef said to Abaye: This deductive inference, that Rav is referring to the mishna, is yours. But in fact Rav was merely saying a halakha unconnected to the mishna. Therefore, there is no proof that Rav was speaking about the carcasses of creeping animals.
וְקַלְּסֵיהּ רַבִּי יוֹחָנָן. מֵיתִיבִי: הָאֵיבָרִין – אֵין לָהֶן שִׁיעוּר, אֲפִילּוּ פָּחוֹת מִכְּזַיִת נְבֵלָה וּפָחוֹת מִכַּעֲדָשָׁה מִן הַשֶּׁרֶץ – מְטַמְּאִין. וְאָמַר רַבִּי יוֹחָנָן: אֵין לוֹקִין עֲלֵיהֶן אֶלָּא בִּכְזַיִת!
The Gemara stated: And Rabbi Yoḥanan praised Rabbi Yosei bar Rabbi Ḥanina for citing the baraita that rules that one is liable for violating the prohibition of eating a creeping animal by the amount of a lentil-bulk. The Gemara raises an objection from a mishna (Oholot 1:7): The whole limbs of impure bodies have no minimum measure with regard to imparting ritual impurity. Even if the limbs were less than an olive-bulk of a carcass or less than a lentil-bulk of a creeping animal, they impart ritual impurity. And Rabbi Yoḥanan says: This mishna is referring to the halakhot of ritual impurity; but with regard to the minimum measure which renders one liable for consumption, one is flogged for eating them only if they amount to an olive-bulk.
אָמַר רָבָא: בְּמוּבְדָּלִין דִּבֵּר הַכָּתוּב.
Rava says in resolution of the apparent contradiction between Rabbi Yoḥanan’s statements: When Rabbi Yoḥanan said that one is flogged for eating even a lentil-bulk of a creeping animal, he was referring only to those eight creeping animals of which the verse speaks, which are separated from all other creeping animals. The Torah (Leviticus 11:29–32) lists eight types of creeping animals, and Rabbi Yoḥanan was referring specifically to those eight. He maintains that one is flogged for eating a lentil-bulk of such creatures, whereas in the case of other creeping animals one is flogged only for eating an olive-bulk of them.
אֲמַר לֵיהּ רַב אַדָּא בַּר אַהֲבָה לְרָבָא: אֶלָּא מֵעַתָּה, בְּהֵמָה נָמֵי, לִיפְלְגִי בֵּין מוּבְדֶּלֶת לְשֶׁאֵינָהּ מוּבְדֶּלֶת.
Rav Adda bar Ahava said to Rava: If that is so, that there is a difference in the measure of liability for consumption between various types of creeping animals, the same should also apply with regard to an animal. Since the Torah in Leviticus 20:25 juxtaposes both kosher animals and non-kosher animals to creeping animals, one can say that an analogous difference should apply here as well: Let the halakha distinguish between flesh from the carcass of kosher animals, which is separated from other types in that it is permitted in consumption by the Torah, and flesh from the carcass of a non-kosher animal, which is not separated, i.e., which is not permitted by the Torah. Consequently, if the carcass of a kosher animal imparts ritual impurity by the amount of an olive-bulk of flesh, the measure of flesh from the carcass of a non-kosher animal that imparts ritual impurity should be larger, i.e., an egg-bulk.

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.

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 was exposed to Talmud in high school, but I was truly inspired after my daughter and I decided to attend the Women’s Siyum Shas in 2020. We knew that this was a historic moment. We were blown away, overcome with emotion at the euphoria of the revolution. Right then, I knew I would continue. My commitment deepened with the every-morning Virtual Beit Midrash on Zoom with R. Michelle.

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!

What a great experience to learn with Rabbanit Michelle Farber. I began with this cycle in January 2020 and have been comforted by the consistency and energy of this process throughout the isolation period of Covid. Week by week, I feel like I am exploring a treasure chest with sparkling gems and puzzling antiquities. The hunt is exhilarating.

3 years ago, I joined Rabbanit Michelle to organize the unprecedented Siyum HaShas event in Jerusalem for thousands of women. The whole experience was so inspiring that I decided then to start learning the daf and see how I would go…. and I’m still at it. I often listen to the Daf on my bike in mornings, surrounded by both the external & the internal beauty of Eretz Yisrael & Am Yisrael!

A friend mentioned that she was starting Daf Yomi in January 2020. I had heard of it and thought, why not? I decided to try it – go day by day and not think about the seven plus year commitment. Fast forward today, over two years in and I can’t imagine my life without Daf Yomi. It’s part of my morning ritual. If I have a busy day ahead of me I set my alarm to get up early to finish the day’s daf

I’ve been wanting to do Daf Yomi for years, but always wanted to start at the beginning and not in the middle of things. When the opportunity came in 2020, I decided: “this is now the time!” I’ve been posting my journey daily on social media, tracking my progress (#DafYomi); now it’s fully integrated into my daily routines. I’ve also inspired my partner to join, too!

I saw an elderly man at the shul kiddush in early March 2020, celebrating the siyyum of masechet brachot which he had been learning with a young yeshiva student. I thought, if he can do it, I can do it! I began to learn masechet Shabbat the next day, Making up masechet brachot myself, which I had missed. I haven’t missed a day since, thanks to the ease of listening to Hadran’s podcast!

I started learning Gemara at the Yeshivah of Flatbush. And I resumed ‘ברוך ה decades later with Rabbanit Michele at Hadran. I started from Brachot and have had an exciting, rewarding experience throughout seder Moed!
Anne Mirsky
Maale Adumim, Israel
I was moved to tears by the Hadran Siyyum HaShas. I have learned Torah all my life, but never connected to learning Gemara on a regular basis until then. Seeing the sheer joy Talmud Torah at the siyyum, I felt compelled to be part of it, and I haven’t missed a day!
It’s not always easy, but it is so worthwhile, and it has strengthened my love of learning. It is part of my life now.
Michelle Lewis

I started learning after the siyum hashas for women and my daily learning has been a constant over the last two years. It grounded me during the chaos of Corona while providing me with a community of fellow learners. The Daf can be challenging but it’s filled with life’s lessons, struggles and hope for a better world. It’s not about the destination but rather about the journey. Thank you Hadran!
Dena Lehrman
אפרת, Israel
I heard about the syium in January 2020 & I was excited to start learning then the pandemic started. Learning Daf became something to focus on but also something stressful. As the world changed around me & my family I had to adjust my expectations for myself & the world. Daf Yomi & the Hadran podcast has been something I look forward to every day. It gives me a moment of centering & Judaism daily.
Talia Haykin
Denver, United States
In January 2020, my teaching partner at IDC suggested we do daf yomi. Thanks to her challenge, I started learning daily from Rabbanit Michelle. It’s a joy to be part of the Hadran community. (It’s also a tikkun: in 7th grade, my best friend and I tied for first place in a citywide gemara exam, but we weren’t invited to the celebration because girls weren’t supposed to be learning gemara).
Sara Averick
Jerusalem, Israel
I tried Daf Yomi in the middle of the last cycle after realizing I could listen to Michelle’s shiurim online. It lasted all of 2 days! Then the new cycle started just days before my father’s first yahrzeit and my youngest daughter’s bat mitzvah. It seemed the right time for a new beginning. My family, friends, colleagues are immensely supportive!
Catriella Freedman
Zichron Yaakov, Israel
Hadran entered my life after the last Siyum Hashaas, January 2020. I was inspired and challenged simultaneously, having never thought of learning Gemara. With my family’s encouragement, I googled “daf yomi for women”. A perfecr fit!
I especially enjoy when Rabbanit Michelle connects the daf to contemporary issues to share at the shabbat table e.g: looking at the Kohen during duchaning. Toda rabba

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.

The mishna taught that all carcasses join together, which indicates that carcasses of non-kosher animals join together with carcasses of kosher animals, only with regard to ritual impurity. But with regard to the prohibition of eating animal carcasses, kosher animal carcasses are distinct, i.e., they join together only with other kosher animals, and non-kosher animal carcasses are likewise distinct. And Levi says: Even with regard to the prohibition of eating animal carcasses, kosher and non-kosher carcasses join together.

And Rav Asi says: Kosher animal carcasses are distinct, and non-kosher animal carcasses are distinct. Since Rav Asi did not specify whether he is referring only to eating or also to ritual impurity, there are those who say that Rav Asi disagrees with the opinion of Rav, i.e., he interprets the mishna as referring to all carcasses of a similar kind, that is, from kosher animals on the one hand, and from non-kosher animals on the other hand.

The Gemara raises an objection against the first explanation of the opinion of Rav Asi from a baraita: With regard to half an olive-bulk from the carcass of a dead cow and half an olive-bulk from the flesh of a live camel, they do not join together with one another. It can be inferred from here that if both of them are dead, they do join together. Rav can explain this baraita as referring to ritual impurity, but this poses a difficulty to Rav Asi.
אֵימָא: הָא חַיֵּי שְׁנֵיהֶם – מִצְטָרְפִין, וּמַנִּי – רַבִּי יְהוּדָה הִיא, דְּאָמַר: אֵבֶר מִן הַחַי נוֹהֵג בַּטְּמֵאָה.
The Gemara answers: One should say that the correct inference from the baraita is not that if both of them, the cow and the camel, are dead, then they join together. Rather, one should infer that if both of them are alive, they join together. And who is the tanna of the baraita? It is Rabbi Yehuda, who said: The prohibition of eating a limb from a living animal applies even to the limb of a non-kosher animal.
אֲבָל מִיתַת שְׁנֵיהֶם, מַאי? לָא מִצְטָרְפִי? אִם כֵּן, מַאי אִירְיָא דְּרָהֵיט וְתָנֵי ״מִיתַת פָּרָה וְחַיֵּי גָמָל״, הָא אֲפִילּוּ מִיתַת שְׁנֵיהֶם לָא מִצְטָרְפִי!
The Gemara raises a difficulty with this answer. But in that case, what is the halakha if both of them, the cow and the camel, are dead? Do they not join together? If so, why does the tanna run specifically to an extreme case and teach: Half an olive-bulk from the carcass of a dead cow and half an olive-bulk from the flesh of a live camel? After all, even if both of them are dead, they do not join together.
וְעוֹד, תַּנְיָא: חֲצִי זַיִת פָּרָה בְּחַיֶּיהָ וַחֲצִי זַיִת גָּמָל בְּמִיתָתָהּ – אֵין מִצְטָרְפִין. אֲבָל חֲצִי זַיִת מִפָּרָה וַחֲצִי זַיִת מִגָּמָל, בֵּין בְּחַיֶּיהָ בֵּין בְּמִיתָתָהּ – מִצְטָרְפִין. קַשְׁיָא רֵישָׁא אַסֵּיפָא! אֶלָּא לָאו שְׁמַע מִינַּהּ: מִיתַת שְׁנֵיהֶם – מִצְטָרְפִין!?
And furthermore, it is taught in a baraita: Half an olive-bulk from the flesh of a cow when it is alive and half an olive-bulk from the carcass of a camel when it is dead do not join together; but half an olive-bulk from a cow and half an olive-bulk from a camel, whether alive or dead, do join together.

He maintains that the prohibition of eating an animal carcass takes effect even with regard to the flesh of a non-kosher animal, which is already prohibited, and for this reason the two half olive-bulks join together, as the same prohibition against eating an animal carcass applies to both.

§ Rav Yehuda says that Rav says: With regard to eating creeping animals, one is flogged for eating an olive-bulk of them. What is the reason? It is because the term “eating” is written in the Torah with regard to them. The verse states: “And every creeping thing that swarms upon the earth is a detestable thing; it shall not be eaten” (Leviticus 11:41). The term “eating” is invariably referring to consuming an olive-bulk.

The Gemara raises a difficulty. But didn’t Rabbi Yosei bar Rabbi Ḥanina teach the following baraita before Rabbi Yoḥanan: The verse states: “You shall separate between the kosher animal and the non-kosher, and between the non-kosher bird and the kosher; and you shall not make your souls detestable by animal, or by bird, or by anything that swarms on the ground, which I have set apart for you as impure” (Leviticus 20:25). The verse opens with eating creeping animals, in the phrase “You shall not make your souls detestable,” and it ends with the ritual impurity of creeping animals: “Which I have set apart for you as impure.”
מָה טוּמְאָה בְּכַעֲדָשָׁה, אַף אֲכִילָה בְּכַעֲדָשָׁה. וְקַלְּסֵיהּ רַבִּי יוֹחָנָן, וְקַשְׁיָא לִדְרַב!
The baraita explains: This teaches that just as the carcass of a creeping animal imparts ritual impurity through contact when it is the volume of a lentil-bulk, so too, one is liable for the prohibition of eating a creeping animal when it is the volume of a lentil-bulk. And Rabbi Yoḥanan praised [vekilseih] Rabbi Yosei bar Rabbi Ḥanina for citing this baraita. And this poses a difficulty to the opinion of Rav, who maintains that one is flogged only if he eats an olive-bulk of creeping animals.
לָא קַשְׁיָא: כָּאן – בְּמִיתָתָן, כָּאן – בְּחַיֵּיהֶן.
The Gemara answers: This is not difficult. Here, the baraita is referring to eating creeping animals when they are dead, at which stage they impart ritual impurity and one is liable for eating a lentil-bulk. By contrast, there, Rav is speaking about eating creeping animals when they are alive, which do not yet impart ritual impurity. For this reason one is flogged only if he eats an olive-bulk.
אֲמַר לֵיהּ אַבָּיֵי: וְהָא רַב אַמַּתְנִיתִין קָאֵי, וּמַתְנִיתִין ״כׇּל הַשְּׁרָצִים״ קָתָנֵי, אֲפִילּוּ בְּמִיתָתָן. לָאו דְּאִיכָּא פּוּרְתָּא מֵהַאי וּפוּרְתָּא מֵהַאי? אֲמַר לֵיהּ רַב יוֹסֵף: הָהִיא דִּיּוּקָא דִּילָךְ הוּא. רַב – שְׁמַעְתָּא בְּעָלְמָא קָאָמַר.
Abaye said to Rav Yosef: But in his statement Rav was referring to the mishna, and the mishna teaches: And all the creeping animals join together to constitute the requisite olive-bulk measure to render one who consumes it liable to receive lashes. This indicates that this halakha applies even when they are dead. Is the mishna not referring to a case where there is a bit of this live creeping animal and a bit of that carcass of a creeping animal, which together combine to amount to an olive-bulk? Rav Yosef said to Abaye: This deductive inference, that Rav is referring to the mishna, is yours. But in fact Rav was merely saying a halakha unconnected to the mishna. Therefore, there is no proof that Rav was speaking about the carcasses of creeping animals.
וְקַלְּסֵיהּ רַבִּי יוֹחָנָן. מֵיתִיבִי: הָאֵיבָרִין – אֵין לָהֶן שִׁיעוּר, אֲפִילּוּ פָּחוֹת מִכְּזַיִת נְבֵלָה וּפָחוֹת מִכַּעֲדָשָׁה מִן הַשֶּׁרֶץ – מְטַמְּאִין. וְאָמַר רַבִּי יוֹחָנָן: אֵין לוֹקִין עֲלֵיהֶן אֶלָּא בִּכְזַיִת!
The Gemara stated: And Rabbi Yoḥanan praised Rabbi Yosei bar Rabbi Ḥanina for citing the baraita that rules that one is liable for violating the prohibition of eating a creeping animal by the amount of a lentil-bulk. The Gemara raises an objection from a mishna (Oholot 1:7): The whole limbs of impure bodies have no minimum measure with regard to imparting ritual impurity. Even if the limbs were less than an olive-bulk of a carcass or less than a lentil-bulk of a creeping animal, they impart ritual impurity. And Rabbi Yoḥanan says: This mishna is referring to the halakhot of ritual impurity; but with regard to the minimum measure which renders one liable for consumption, one is flogged for eating them only if they amount to an olive-bulk.
אָמַר רָבָא: בְּמוּבְדָּלִין דִּבֵּר הַכָּתוּב.
Rava says in resolution of the apparent contradiction between Rabbi Yoḥanan’s statements: When Rabbi Yoḥanan said that one is flogged for eating even a lentil-bulk of a creeping animal, he was referring only to those eight creeping animals of which the verse speaks, which are separated from all other creeping animals. The Torah (Leviticus 11:29–32) lists eight types of creeping animals, and Rabbi Yoḥanan was referring specifically to those eight. He maintains that one is flogged for eating a lentil-bulk of such creatures, whereas in the case of other creeping animals one is flogged only for eating an olive-bulk of them.
אֲמַר לֵיהּ רַב אַדָּא בַּר אַהֲבָה לְרָבָא: אֶלָּא מֵעַתָּה, בְּהֵמָה נָמֵי, לִיפְלְגִי בֵּין מוּבְדֶּלֶת לְשֶׁאֵינָהּ מוּבְדֶּלֶת.
Rav Adda bar Ahava said to Rava: If that is so, that there is a difference in the measure of liability for consumption between various types of creeping animals, the same should also apply with regard to an animal. Since the Torah in Leviticus 20:25 juxtaposes both kosher animals and non-kosher animals to creeping animals, one can say that an analogous difference should apply here as well: Let the halakha distinguish between flesh from the carcass of kosher animals, which is separated from other types in that it is permitted in consumption by the Torah, and flesh from the carcass of a non-kosher animal, which is not separated, i.e., which is not permitted by the Torah. Consequently, if the carcass of a kosher animal imparts ritual impurity by the amount of an olive-bulk of flesh, the measure of flesh from the carcass of a non-kosher animal that imparts ritual impurity should be larger, i.e., an egg-bulk.
