1)

(a) We just cited the ruling of Rebbi Yochanan in the name of Rebbi Shimon ben Yehotzadak, that public expanses of water *cannot become Asur*.
What problem do we have with the implication that water belonging to a private person *can*?

(b) How do we resolve the problem?

(c) What unresolved She'eilah from the previous Perek (regarding the opinions of B'nei Rebbi Chiya and Rebbi Yochanan) do we now try to resolve from here?

(d) Bearing in mind that their Machlokes involved stones that came loose by themselves, how do we refute this proof?

(a) When Rebbi Chiya bar Aba arrived in Gavla, what did he say when he saw ...

1. ... Jewish women who were pregnant from potential Geirim who had performed Milah but not Tevilah?
2. ... Yisre'elim drinking wine which Nochrim had diluted?
3. ... Yisre'elim eating Turmus beans that had been cooked by Nochrim? What are Turmus beans?

(b) What did Rebbi Yochanan instruct Rebbi Chiya bar Aba to go and tell the residents of Gavla regarding each of the three cases?

(c) We already cited Rebbi Yochanan's reason for his second ruling ('Lech Lech Amrin li'Nezira ... ').
But what is the basis of his first ruling (regarding children born from a Ger who performed Milah but not Tevilah)?

(d) How will we reconcile this ruling with the Halachah that only a child from a relationship involving incest (which carries with it a Chiyuv Kareis) is a Mamzer?

(a) What does Rav Shmuel bar Rav Yitzchak Amar Rav say about any food that can be eaten raw?

(b) In that case, seeing as Turmus beans cannot be eaten raw, why did Rebbi Yochanan need to come on to the reason of 'Einan B'nei Torah' to forbid the Turmus beans in Gavla? Why were they not forbidden anyway?

(a) What did Rav Kahana reply when they asked him whether a Nochri is permitted to carry the grapes to the wine-press?

(b) What does the Beraisa rule in a case where a Nochri carried baskets or small barrels, of grapes from which juice was oozing, to the wine-press?

(c) What did Rebbi Yochanan reply, when Rav Yeimar queried him from this Beraisa?

5)

(a) What did that Nochri do when he saw an Esrog fall into a barrel of wine?

(b) Which two instructions did Rav Ashi issue to those who were present?

(a) What concession did Rav Ashi make to someone whose barrel of wine a Nochri was Menasech, bearing in mind that he is not permitted to sell it to any other Nochri?

(b) What is the reason for this concession?

(c) Rav Ashi took his cue from a Beraisa.
The Tana Kama there forbids benefitting from wine that a Nochri was Menasech not in the presence of the Avodah-Zarah.
What two reasons do Rebbi Yehudah ben Bava and Rebbi Yehudah ben Beseira give for permitting it?

(d) Does this mean that Rav Ashi holds like the two Rebbi Yehudahs?

(a) In a case where the tap of a barrel of wine broke off, and a Nochri placed his hand over the hole to prevent the wine from flowing out, Rav Papa permits all the wine that is not actually next to the hole.
Why is that?

(b) Why did he only forbid drinking the wine, and not deriving benefit from it?

(c) What does he say in the second Lashon, where he is not so lenient?

(d) Based on a Mishnah in T'vul-Yom that we are about to cite (which discusses this ruling), why is the Halachah not like Rav Papa?
