Question: How did we establish the case ((of the Beraisa in 17-1(i) above), that one burns the Terumah Teluyah at nightfall of Shabbos? It was referring to a case where he intends to approach a Chacham to undo it. If so, why is he burning it rather than approaching the Chacham)?

Answer (Rebbi Yosi bai Rebbi Bun): The doubtful tumah status came about close to nightfall. (Therefore he did not have time to go to a Chacham.) Consequently, one cannot learn anything from the Beraisa.

(Referring back to 17-1(d) above): You also said that the second barrel follows Rebbi Meir, but Rebbi Yosi does not agree.

Question #1 (Beraisa on the case of the second barrel (above in 16,1,(g),1): Rebbi Eliezer and Rebbi Yehoshua agree that if he is able to save a revi'is of the Terumah from becoming Tamei (before falling into the lower winepress), he should do so). When was this said? When the pit (the lower winepress) contains enough Chulin (101 parts) to be able to annul the revi'is of Terumah wine that will fall into it (and consequently he will still be able to consume the mixture rather than it go to waste). But if it does not contain enough Chulin to do so, one may not even Metamei a minute amount (since one will not be able to consume the mixture).

Conclusion of question: And if you say that the Beraisa follows Rebbi Meir (as above 17-1(d) & 18-1(c)), whether or not the pit contains enough Chulin to annul the Terumah, it should still be prohibited?

Question #2: When Rebbi Yosi said (above Halachah 16-1(b)) 'It is not possible to learn this from their words'; surely he would only say this if he agreed to the first case?! (Otherwise, even if they would be comparable, he would not learn from it.)

Question: If the Beraisa follows Rebbi Yosi, why does Rebbi Yehoshua permit being Metamei it, since according to Rebbi Yosi it is prohibited to actively make it impure, even if it is going to waste?

Answer: There (the case of the barrel), Rebbi Yehoshua's reasoning is in order to save Jewish money, by refraining from wasting the Tamei Chulin in the winepress (since when the Terumah falls into it, it will be prohibited to all). However, here (Erev Pesach) he is not wasting Jewish money since it must anyway be destroyed.

Question: Surely he is wasting Jewish money by using extra wood to make two fires?

Answer: They were concerned only for a large loss but not for a small loss.

Suggestion (Rebbi Chananyah to Rebbi Mana): One could answer that when Rebbi Meir said 'from their words', he was referring to the words of Rebbi Akiva and Rebbi Chanania Segan HaKohanim (see 16-1(d)), and nothing can therefore be learned from it. (One could say that all agree to the Beraisa of the barrel and on Erev Pesach the reason is because it has already come to a Rabbinic pasul. Therefore Rebbi Yosi objected and said that the two are not comparable, as over there it is Tamei and Tamei, but here is pasul and Tamei.)

(RebbiZeira/Rebbi Ila quoting Rebbi Elazar): (Disagrees with (w) above) The first barrel follows Rebbi Yosi, the second barrel follows both Rebbi Meir and Rebbi Yosi.

Objection (Rebbi Zeira to Rebbi Mana): Does it (the case of the second barrel) not disagree with Rebbi Yosi? (Rebbi Yehoshua permits being actively Metamei, since it is going to waste. He does not agree with the statement earlier (in (h)) that it is because of wasting Chulin.)

Correction: The second barrel does not follow Rebbi Yosi (but does follow Rebbi Meir).

Suggestion: The first barrel does not follow Rebbi Meir, as we find that Rebbi Yosi always permits burning Teluyah.

(Rebbi Mana): I once went to Kisarin and heard Rebbi Zerikan saying in the name of Rebbi Zeira that Rebbi Meir always permits burning Teluyah. I responded to him that Rebbi Meir only said it about a Torah doubt. (However, he does not permit burning a Teluyah that is only due to a Rabbinic doubt, such as the first case of the barrel.) Rebbi Zerikan replied that that is correct, but Rebbi Meir permits burning even a Rabbinic doubt in the case of homes of gentiles. (Chazal decreed a tumah upon them, as gentiles bury their miscarried fetuses there.)
