Avodah Zarah 76

AVODAH ZARAH 72-76 - Sponsored by a generous grant from an anonymous donor. Kollel Iyun Hadaf is indebted to him for his encouragement and support and prays that Hashem will repay him in kind.


(a) Tana'im argue over whether food that is prepared in a Nochri's un-Kashered utensil, on the following day, is permitted or not.
What is the reason of the Tana who permits it?

(b) In that case, why does the Torah require Hag'alah?

(c) Then why are utensils obtained from a Nochri not permitted Lechatchilah after the first day?

(a) Why does the second Tana then forbid even Bedi'eved, utensils, even after the first day. Why are they not permitted because of 'Nosen Ta'am li'Fegam'?

(b) What does the Mishnah in Zevachim say about Kashering a spit-rod and a grill of Kodshim?

(c) What was Rav Sheishes' reaction when Rav Amram asked from there on to our Mishnah, which requires Libun (in fire)?

(a) Why did Rabah disagree with Rav Sheishes' differentiation? Why did he consider Kodshim to be 'Isura Bala'?

(b) So how did he interpret the 'Hag'alah' in Zevachim?

(c) What kind of Kashering do Kodshim vessels then require, according to Rabah?

(d) On what grounds did Abaye object to Rabah's interpretation of Hag'alah?

(a) To resolve the discrepancy, Abaye explained 'Yagid Alav Rei'o'.
What did he mean by that?

(b) Do Kodshim utensils still require Sh'tifah ve'Hadachah?

(c) What objection did Rava raise to Abaye's explanation? What ought at least one of the Mishnah's to have said?

(a) So Rava cited Rav Nachman Amar Rabah bar Avuhah to explain the Mishnah in Zevachim. What does Rav Nachman mean when he says 'Kol Yom ve'Yom Na'aseh Gi'ul la'Chavero'?

(b) Why do we agree with Rav Nachman with regard to the Korban Shelamim, but query him from the Chatas?

(c) How can we circumvent this problem? How is it possible to ensure that what is absorbed in the walls of the pots will always become 'Nosen Ta'am li'Fegam' first?

(d) What (unanswerable) problem do we have with this?

(a) To explain the difference between Kodshim and Chulin, Rav Papa explains 'Hai Karid, Hai Lo Karid'.
What does he mean by that?

(b) Rav Ashi accepts Rav Sheishes' initial answer (which considers Kodshim 'Heteira Bala').
How does he refute Rabah's objection ('Ki ka'Palit, Isura ka'Palit')?

(a) How does ...
  1. ... Rav Mani define the Shiur of Libun?
  2. ... Rav Huna explain Hag'alah?
(b) How does one make Hag'alah on a large pot, according to Rav Ukva (or Rav Akavya)?

(c) When Rava heard this, he exclaimed that only Rav Ukva, who was very wise, would have made such a statement.
What was so wise about his ruling?
On which principle was it based?

(d) Then why is the rim of dough around the edge necessary?

Answers to questions



(a) What does Rav Ukva bar Chama rule with regard to a knife.
What must one do after having filed it?

(b) What kind of earth is required for this, according to Rav Huna b'rei de'Rav Yehoshua?

(c) This Halachah seems rather excessive (assuming that 'Shafah' means 'files with a grindstone').
How do others therefore explain 'Shafah' in our Mishnah?

(d) How does Rav Kahana (supported by a Beraisa) qualify the above ruling?
Which sort of knife does he preclude from this method of Kashering?

(a) Rav Huna b'rei de'Rav Yehoshua qualifies this concession still further. Under which circumstances can one not rely on this method of Kashering, according to him?

(b) When an Esrog was brought before Shavur Malka (King of Persia), what distinction did he make, when after cutting himself a piece, he cut a piece to give to Bati bar Tuvi and another piece to give to Rav Yehudah?

(c) What did he reply when Bati bar Tuvi asked him whether he thought that Rav Yehudah was a Jew and he wasn't?

(d) In the second answer, he (Shavur Malka) reminded him of what had happened the night before.
What incident was he referring to?
