Question (against R. Yonah and R. Yosi - Mishnah): After Churban Beis ha'Mikdash, R. Yochanan ben Zakai enacted that the entire day of waving [and offering the Omer] is forbidden (lest people be used to eating Chadash on the 16th, and they will do so also after the Mikdash is rebuilt, and it is forbidden until the Omer is offered).

If you will say [that R. Yochanan agrees there is] a Torah Isur, this is fine. [However,] if you will say [that he holds that] the Isur is mid'Rabanan, do we make an enactment after (i.e. in order to guard) an enactment?!

Answer (R. Yosi bei R. Bun): This is due to people far [from the Mikdash, who will not know when it is offered. Normally, we assume that it is offered before midday, but if the Mikdash is built (descends from Shamayim) towards the end of the 15th or the following night, perhaps they will not be able to offer it until the end of the 16th - HA'GAON RAV C. KANIEVSKY, SHLITA, based on Rosh Hashanah 30b].

(R. Yirmeyah citing R. Chiya): Both when there is a Korban, and when there is no Korban, the day permits. (This is just like R. Yochanan said above. Why didn't we challenge him, like we now challenge R. Yirmeyah? PNEI MOSHE - R. Yirmeyah connotes that there is no Isur at all before it is offered; R. Yochanan said that there is an Isur.)

Question #1 (against R. Yirmeyah - Rav Huna): The Beraisa [from which Chizkiyah learned] argues with [R. Yirmeyah]!

(Beraisa): "Ad Etzem ha'Yom ha'Zeh" teaches that the day permits.

Suggestion: Perhaps this is even when there is a Korban!

Rejection: "Ad Havi'achem Es Korban Elokeichem" (it is permitted only from when the Korban is brought).

Question #2 (against R. Yirmeyah - Mishnah): After Churban Beis ha'Mikdash, R. Yochanan ben Zakai enacted that the entire day of waving is forbidden. (If the day permits even while the Mikdash stands, there is no reason to decree!)

Answer (R. Yonah): I asked this to R. Yirmeyah, and he said that [R. Yochanan ben Zakai] can hold like R. Yehudah, for R. Yehudah says that it is forbidden mid'Oraisa [until the end of the day, for he holds Ad v'Ad bi'Chlal - R. SHLOMO SIRILIYO].

There (in Bavel, some) were concerned for the great fast (Yom Kipur, and fasted) for two days (we assume that that Elul was short, but if Beis Din was Me'aber Elul, Yom Kipur is on what we assume to be the 11th);

Rav Chisda (to those people): Why do you enter yourselves into Safek danger?! There is a Chazakah that Beis Din is not lazy! (If they were Me'aber Elul, they would have sent Sheluchim to inform us.)

The father of Shmuel bar Rav Yitzchak was concerned for himself, and fasted two days. His small intestines snapped, and he died. (We explained this like R. SHLOMO SIRILIYO, GRA.)
