(a) Rava establishes our Mishnah specifically by a tub that has been tarred by a Nochri. What will the Din then be in a case where a Nochri treads the grapes in a tub that has not been tarred. What will the Din then be in a case where a Nochri treads grapes in a tub that has not been tarred?
(b) Why does Rava need to tell us this? Why is it not obvious from our Mishnah, which states 'she'Zafsah Akum'?
(c) What does Rava say in the second Lashon about a Nochri who treads grapes in a tarred tub?
(d) Here again, we ask why this is not obvious from the Mishnah itself. What do we answer?

(a) The Beraisa discusses an earthenware wine-tub itself and the jar and the funnel (from the wine-press) that have been tarred by a Nochri. Rebbi permits them with Niguv alone. What do the Chachamim say?
(b) How do we know that the Tana so far is speaking a. about earthenware vessels, and b. about an untarred wine-press?
(c) Rebbi concedes to the Chachamim that (even untarred) jars require Kiluf (even though a wine-press does not). Why is that? What makes the former more stringent than the latter?

(a) How do we reconcile our Mishnah, which permits Niguv in the case of a stone tub that a Nochri tarred, and according to Rebbi, even a wooden one, with the Beraisa, which requires a tarred tub to be peeled, even if it is made of stone?
(b) What problem do we have with the Beraisa, where Rebbi permits an earthenware tub, jar and funnel with mere Niguv?
(c) Like whom does Rava establish the Seifa of our Mishnah, to resolve the discrepancy?
(d) What does Rebbi now hold regarding...
1. ... a tarred tub made of stone or of wood?
2. ... a tarred tub made of earthenware?
3. ... an untarred tub made of earthenware?

(c) Why did he do that?

(a) According to Rav, they performed Niguv using water. What does Rabah bar bar Chanah say?
(b) On what grounds do we object to both opinions?
(c) So what does each Amora really mean?
(d) We conclude that in fact, they do not argue, because one is referring to different cases, 'Ha bi'Retivta, ve'ha be'Yabeshta'. What does this mean?
(e) Who says what?
