1)

(a) The Mishnah in Terumos lists three liquids that are forbidden because of Giluy.
What are they?

(b) The Tana gives the time period in which they become forbidden as the time it takes for a poisonous snake to come from close by and drink. How does Rebbi Yitzchak b'rei de'Rav Yehudah define 'from close by'?

(c) We amend the Beraisa by adding 'Ve'yachzor le'Choro'.
What forces us to do this?

(a) If after Shechting and breaking bones all day with the same knife, it is found to be defected, Rav Huna invalidates the Shechitah.
Why is that?

(b) What does Rav Chisda say?

(c) What do we mean when we say that Rav Huna follows his own reasoning?
Which reasoning are we referring to?

(d) What does Rav Chisda say about this? Which principle overrides the Chezkas Isur?

(a) Rava cites a Beraisa in support of Rav Huna.
What does the Beraisa say about someone who Tovels and who, at the end of the day, discovers a Chatzitzah consisting of a species with which he was working all day?

(b) How do we reject out of hand, the counter-argument that the case of Tevilah and that of Shechitah are not comparable, because ...

1. ... the Tamei person has a Chazakah that he has not Toveled?
2. ... 'Harei Shechutah Lefanecha'?
3. ... that a 'Re'usa' occurred (in connection with the Tevilah)?

(c) Rav Chisda nevertheless counters Rav Huna using this last argument.
What does he say?

(a) What does the Shechitah of a bird entail?

(b) What does the Beraisa say about a case where, after Shechting the Veshet, the Gargeres slips from its place? What are 'Veshet' and 'Gargeres' respectively?

(c) Why does the Tana give this example, and not vice-versa (where he Shechted the Gargeres first, before the Veshet slipped from its place)?

(d) What does the Tana say in a case where the Gargeres slipped ...

1. ... before he Shechted the Veshet?
2. ... but they do not know whether it slipped before or after the Shechitah of the Veshet?

(a) 'Kol Safek bi'Shechitah Pasul' however, is a 'Ribuy'.
What do we initially think it comes to include that poses a Kashya on Rav Chisda?

(b) How do we refute the Kashya? If it does not come to include a Safek in the knife, which case of Safek *does* it come to include?

(c) Why is that? On what grounds does would the Tana prefer to include the latter (according to Rav Chisda), rather than a Safek in the knife, according to Rav Chisda?

6)

(a) Under which circumstances do we rule ...

1. ... like Rav Huna?
2. ... like Rav Chisda?

(b) On what basis does Rav Chisda render the Shechitah Kasher even if the Shochet did not cut bones after the Shechitah?

(a) There was a case where, after a Shochet had Shechted thirteen animals, Rav Yosef declared them Tereifah.
Why did he do that?

(b) What do we mean when we ...

1. ... suggest that Rav Yosef follows the opinion of Rav Huna?
2. ... counter that he might even hold like Rav Chisda?
3. ... conclude that he must hold like Rav Huna after all? On what grounds would Rav Chisda have permitted all the animals, right down to the last one?

(a) Rav Acha b'rei de'Rava told Rav Ashi that Rav Kahana required the knife to be inspected after each Shechitah.
What do we mean when we ...

1. ... suggest that he follows the opinion of Rav Huna?
2. ... counter that he might even hold like Rav Chisda?

(b) But did we not just conclude that according to Rav Chisda, we ascribe the defect to the neck-bone of the last animal?

(c) In spite of what we have just said, how does Rav Kahana really hold?

(a) This prompts to ask why the Shochet is not obligated to give his knife to a Chacham for inspection, following the Shechitah of each animal.
Why do we only ask it (at this point), on Rav Chisda, and not on Rav Huna?

(b) What do we answer?

(c) How do we then interpret the Pasuk "al-Pi Shenayim Eidim Yakum Davar"?

(d) Why then, is the Shochet obligated to show the Chacham his knife before he begins to Shecht?

(a) What does Rebbi Shmuel bar Nachmeni Amar Rebbi Yonasan learn from the Pasuk in Tazri'a (in connection with Tzara'as Batim) "Ve'yatza ha'Kohen min ha'Bayis el Pesach ha'Bayis, Ve'hisgir es ha'Bayis Shiv'as Yamim"?

(b) How does Rav Acha bar Ya'akov refute the proof? What sort of 'Yetzi'ah' might the Pasuk expect the Kohen to make?

(c) Abaye disagrees with Rav Acha bar Ya'akov on two scores. One of them is the fact that walking out backwards will not fulfill the requirement "Ve'yatza min ha'Bayis".
What is the other?

(d) And what objection does he raise to the suggestion that one must open a window through which the Kohen can ensure that the Tzara'as is still intact, and has not diminished to less than the minimum Shi'ur?

(a) What does Rava prove from the 'Yetzi'ah' of the Kohen Gadol from the Kodesh Kodshim on Yom Kipur?

(b) And how does he counter Abaye's second objection (regarding opening a window in the door)?

(c) What does the Beraisa learn from the Pasuk ...

1. ... "Ve'yatza ha'Kohen el Pesach ha'Bayis"? What we would have otherwise thought?
2. ... "min ha'Bayis"?
3. ... "Ve'hisgir es ha'Bayis"?

(d) How does Rav Acha reconcile his opinion with this Beraisa?
