(Mishnah): Rebbi Yehudah said further that there were two pasul [Chametz] loaves of the korban toda that would rest on the top of the bench. As long as they were resting there, the people continued to eat. When one was removed, they were Toleh (suspended)- they would not eat but they would also not burn [the Chametz]. When both were removed, the people began to burn [the Chametz].

(Raban Gamliel): Chulin (non-sacred Chametz) may be eaten for the entire 4th hour, (Chametz of) Terumah may be eaten for the entire 5th hour and they burn at the beginning of the 6th.

(Gemara - Rebbi Shimon ben Lakish): [The Toda loaves were not totally invalid, rather] they were kasher (valid).

Question: So in what way were they pasul?

Answer: The sacrifice (which they were supposed to accompany) was not slaughtered. (Note: This answer follows the alternative text which the Korban ha'Edah explains.)

Question: Since the toda had not been slaughtered and therefore they did not have kedushas haguf (they were not consecrated until the time of slaughtering), one should be able to redeem them and eat them?!

Answer (Rebbi Chananyah): There is [already a large amount of] Chulin before him which he will not be able to eat (before the time of biur), so would he redeem [even more Chametz] to eat?!

Answer #2 (instead of 1c) (Rebbi): They were actually pasul (invalid) as many would rush to bring their todas (on Erev Pesach - as on Pesach they could not be brought because they were Chametz), and it was impossible to avoid some of their blood being spilled, thereby invalidating the korban.

(Beraisa): Two cows would be ploughing in Yerushalayim (to be used as a sign as to when Chametz would be prohibited, in the same way that the two loaves were used).

Question: Surely the custom in Yerushalayim was to refrain from melacha (creative labor) in the morning of the 14th?

Answer: They appeared as if they were ploughing.

(Beraisa version #1): Two candles were burning (and they would be an indication, in the same way as the loaves).

(Beraisa version #2): Two sheets were suspended.

Resolution (Rebbi Pinchas): They do not disagree - The cows and candles were used [when the 14th occurred] on a weekday. The sheets were used [when the 14th occurred] on Shabbos.

Question (Rebbi Chananyah to Rebbi Mana): Why did they not blow a shofar as a sign?

Answer: People might mistakenly think that it was for the (morning) Tamid offering (and this would result in people eating Chametz after the permitted time).

Objection (Rebbi Chananyah - Mishnah): They would sound three blasts to stop the people from working and three blasts to signify the beginning of Shabbos. (Why is there no concern that people might mistakenly think that they were for the (afternoon) Tamid offering?)

Answer: Since they would blow every Friday, people would not err; but here (erev Pesach) only occurred once a year, so people might confuse it with the Tamid offering.

Query: Why did Raban Gamliel say that Terumah may be eaten for the entire 5th hour - did Chazal add an hour because of its sanctity or because there are not many people who can eat it (since it is prohibited to non-Kohanim)?

Question: Where is there a practical difference?

Answer: Todah loaves (that are sanctified but are permitted to non-Kohanim). If the reason is because there are not many people who can eat Terumah, all can eat the loaves. If the reason is because of the sanctity of Terumah, these are also sanctified.

Answer (Beraisa - Rebbi Nosson): When they took the [two] kasher loaves (that were placed on top of the bench - see Mishnah in 1a) they continued to eat them for an hour. The Chulin was suspended but not burned.

Proof: The reason for here is not because there are only few people who can eat it (since this does not apply to the toda loaves as non-Kohanim could eat them), rather it is because of their sanctity. Here also, the reason for Terumah is because of its sanctity.

(Rebbi Yuda ben Pazi): It appears that the halacha should follow Raban Gamliel as he (partially) follows both of them (Rebbi Meir in Terumah and Rebbi Yehudah in Chulin (Pnei Moshe)).

Rebbi Avun reiterates this in the name of Rebbi Shimon ben Yutzedek.
