Question: Which Tana's opinion is that the Rosh Hashanah for festivals is in Nisan? R. Shimon, who said that (in order for a person to transgress the prohibition of Bal Te'acher - delaying in bringing a Korban that one vowed to bring), he must pass through 3 festivals in their correct order with the festival of Pesach coming first (i.e. Pesach, Shavuos and Sucos). (Note: This entry follows the explanations of the Pnei Moshe and Rav Chaim Kanievski.)

According to R. Shimon, sometimes he passes through five festivals, sometimes four and sometimes three.

If he vowed before Shavuos, he must pass through five to transgress. If he vowed before Sucos, he must pass through four. If he vowed before Pesach, he must pass through three.

R. Elazar bei R. Shimon: As long as Pesach comes last. Therefore, sometimes he passes through three, sometimes two and sometimes one festival to transgress. (Note: This entry also follows the text of the Pnei Moshe and Rav Chaim Kanievski.)

Chachamim: He transgresses when he passes through three festivals which start from the first one he reaches after his vow.

Beraisa: The Pasuk states (Vayikra 23, 38), "aside from the Shabbasos of Hash-m and aside from your gifts etc.'' What is the purpose of the phrase''...that you shall give to Hashem'' - otherwise I would have thought that one may only bring the Korbanos of the festival on the festival.

What is the source to say that private and public Korbanos that were consecrated both before and on the festival may be brought on the festival? The Pasuk (ibid) states "aside from the Shabbasos of Hash-m...that you shall give to Hashem'' - these are the bird and meal offerings - the Pasuk comes to include all of these, that they may all be brought on the festival.

I might have thought that it is optional to bring them...the Pasuk states (Bamidbar 29, 39), "these you shall perform for Hash-m on your festivals''. "These'' establishes an obligation to bring them on the festival.

I might have thought that one could choose which festival one will bring them... the Pasuk states (Devarim 12, 5-6), "...you will come there. And you will bring there'' -

I might have thought that if one festival passed and he did not bring the Korban, he transgresses Bal Te'acher... the Pasuk states "these you shall perform for Hash-m on your festivals''.

R. Shimon says that he must pass through 3 festivals in order. How is this? If he vowed before Pesach, he transgresses after passing through Pesach, Shavuos and Sucos. If he vowed before Shavuos, he must pass through Shavuos, Sucos, Pesach, Shavuos and Sucos. If he vowed before Sucos, he must pass through Sucos, Pesach, Shavuos and Sucos.

Question (to R. Ila): He transgresses the positive Mitzvah after the 1st festival. What is the source that also then transgresses the negative Mitzvah? The Pasuk states (Devarim 12, 5-6), "...you will come there. And you will bring there''. What is the case? If it is a positive Mitzvah, a positive Mitzvah was already stated ("You shall guard that which comes out of your mouth). Rather, it must be a negative Mitzvah.
