Why is liquid that dripped from grapes forbidden?

(b) Then why is an egg that was laid on Yom-Tov not a Gezeirah li'Gezeirah?

1. ... Rav Yosef ('Peiros ha'Noshrin') decline to learn like Rav Yitzchak ('Mashkin she'Zavu')?
2. ... Rav Yitzchak decline to learn like Rav Yosef?

(a) The Tana Kama of a Beraisa forbids all liquid that drips from a solid on Shabbos and Yom-Tov.
What does Rebbi Yehudah say?

(b) What does Rebbi Yehudah say, with regard to the two days of Rosh Hashanah, concerning ...

1. ... a basket of un'Ma'asered fruit?
2. ... an egg that is laid on the first day?

(c) Inferring from Rebbi Yehudah's words that the egg is Asur on the *first* day of Rosh Hashanah, what discrepancy does Rebbi Yochanan now find between Rebbi Yehudah here, and what he himself said above (in a.)?

(d) What can we extrapolate from Rebbi Yochanan's Kashya regarding his view on why an egg that is laid on Yom-Tov is forbidden?

(a) How does Rebbi Yochanan reconcile the two statements of Rebbi Yehudah?

(b) Ravina disagrees with Rebbi Yochanan's answer.
How does he explain Rebbi Yehudah's statement (in the second Beraisa) that the egg is permitted only on the *second* day, without needing to switch the opinions in the first?

(c) Why will the egg not be forbidden on the first day because of 'Mashkin she'Zavu'?

5) Both Rebbi Yochanan and Ravina established the Beraisa (of 'Beitzah she'Noldah ba'Rishon') by a chicken that was designated to be eaten.

What might one do with a raw egg, other than eat it?

(b) Is one permitted to protect it by covering it with an overturned dish? Why on earth would one have thought that this is forbidden?

(a) Will the egg that is a Safek become permitted if it is inadvertently mixed with many other eggs?

(b) What do we initially think 'u'Sefeika Asurah' means?

(c) What Kashya do we now have on Rav Yosef and Rav Yitzchak? Why is it not a Kashya on Rabah?

(a) We establish the Seifa (of 'u'Sefeika Asurah') by Safek Tereifah, which makes it a Safek d'Oraysa.
What problem do we have with that from the final statement in the Beraisa ('Nis'arvah be'Elef ... ')? Why would this not be difficult if we were talking (as we initially thought we were) about a case of Safek Yom-Tov, Safek Chol?

(b) Why is this not a problem according to our initial interpretation of the Beraisa? Is the fact that a 'Davar she'Yesh Lo Matirin' does not become Batel, mi'd'Oraysa or mi'de'Rabbanan?

(c) We try to explain that the egg is not Batel, because of its importance. According to which Tana will this explanation go?

(d) What is the problem with the explanation?

(a) How much Heter is required for K'lai ha'Kerem to become Batel?

(b) Then why does Rebbi Meir, in the Mishnah in Orlah, hold that bundles of Tilsan (a kind of legume known as fenugreek) of K'lai ha'Kerem are not Batel in two hundred?

(c) What do the Chachamim say?

(a) According to the Chachamim, the only six 'fruits' that do not become Batel are nuts from Perech (possibly coconuts), pomegranates from Baden, sealed barrels of wine, young mangold (a type of beet) -shoots, the cabbage of Eretz Yisrael (which used to be as large as a tree) and a Greek gourd.
Which food does Rebbi Akiva add to the list?

(b) To which of these will the Isur of K'lai ha'Kerem apply, but not Orlah?

(a) Rebbi Yochanan learns in Rebbi Meir 'es she'Darko Limenos'.
What does Resh Lakish say?

(b) How will Rebbi Yochanan explain the Tana of the Beraisa above (who forbids an egg which is a Safek Tereifah that became mixed even with a thousand eggs (see 8a)? Why does it not become Batel?

(a) How much Chulin is required for Terumah to become Batel?

(b) If someone pressed a litra of figs of Terumah in one of many barrels, and doesn't know on top of which barrel that litra is, Rebbi Eliezer and Rebbi Yehoshua argue over when, and even whether, it becomes Batel. According to Rebbi Meir, Rebbi Eliezer includes all the contents of the barrels to make up the hundred that renders the one litra Batel (even though he knows for sure that the litra concerned is on top of the barrel).
Why does Rebbi Eliezer so lenient? What does Rebbi Yehoshua say?

(c) In Rebbi Yehudah's opinion, Rebbi Eliezer holds like Rebbi Yehoshua according to Rebbi Meir.
