Whether a firstborn or other Kodshim, he transgresses after 3 festivals even if less than a year, or a year even less than 3 festivals.

Question: 3 festivals in less than a year is understandable, but how could there be a year with less than 3 festivals?

Answer (in Bavel): If the animal was not yet 8 days old on the first festival, that festival was not viewed as the first festival of the 3.

Question: Why is it not like a firstborn, that its year is counted from its birth (even though it is not valid as a Korban until it is 8 days old). Here also, if it was born on Erev Pesach, for part of Pesach it was a valid Korban, so Pesach should be counted as the first festival?

Answer (R. Aba Mari): When Shavuos occurs on the 5th of Sivan (if Nisan and Iyar were both 30 day months) and the following year, it occurs on the 7th (if Nisan and Iyar were 29 day months).

Question (R. Bun bar Chiya to R. Zeira): The Pasuk states (Vayikra 27, 33), "You will not distinguish between good and bad (in separating Maaser Beheimah)''. If a person chose a good animal, has he transgressed this negative Mitzvah?

Answer (R. Zeira): If a negative Mitzvah comes to permit something (as we will see), a person does not transgress it if he performs it.

What does the Pasuk permit? Consecrating blemished animals.

Mishnah in Maseches Nega'im: (If a Metzora shaved his head on the 7th day) on the 8th day he brings 3 animals - for a Chatas, an Asham and an Olah. A poor man brings a Chatas of a bird and an Olah of a bird.

Question: Surely before he brings the Asham, the bird Chatas is not considered ready for sacrifice (Mechusar Zman)?

Answer (R. Elazar): On this occasion, the Torah permitted consecrating animals that are not ready.

Question (R. Ba bar Mamal to R. Imi): The Pasuk states (Bamidbar 6, 10), "On the 8th day he shall bring''. If a Nazir transgressed and did not bring his Chatas and Olah offerings, has he transgressed Bal Te'acher?

Answer (R. Imi): If a negative Mitzvah comes to permit something, a person does not transgress it if he performs it. What is it coming to permit?

Answer: Like the statement of R. Elazar - for a Nazir, the Torah permitted consecrating animals for his Chatas and Olah at the same time, even though the Olah is not ready until he consecrates the Chatas.

R. Yosi bei R. Bun: "All seven days'' the Nazir may not bring his Korbanos; from the 8th day we force him to bring them.

Question (against R. Yosi BR''B - Beraisa): All who must bring Korbanos wait and bring them at the time of the festival. (If we force the Nazir to bring them on the 8th day, how can he wait until the festival?)

Conclusion of question: It is understandable that a Nazir (can wait as he can eat Kodshim whilst he is a Nazir). However, as for a Metzorah who has not yet brought his Korbanos, the Mishnah teaches that the Mitzvos of Hallel and eating Shelamim meat are performed for all 8 days of Sukos. If a Metzorah does not bring his Korbanos until the festival, he may not actually bring them until after the 1st day of Yom Tov as they are obligatory Korbanos that do not have a specific time. Therefore, he will not be able to eat the Shelamim meat for all 8 days?

Answer: The Beraisa refers to a Nazir (who brings his Korbanos on the festival, but a Metzorah brings them immediately).

Question (R. Zecharia, son-in-law of R. Levi): The first part about a Nazir is understandable but the latter part about a Metzorah (needs explanation) -

Answer (R. Chananya son of R. Hillel): You already asked this there and R. Yosi said that R. Avduma Nechusa established that when the Mishnah says that Mitzvah of Simcha is observed for 8 days, it refers to Kohanim since they still have the meat of goat offering that is brought on Shabbos. Here also, (the Metzora only has seven days, but) the Kohanim have eight days because they eat the Korbanos on Shabbos.

Question (R. Chagai to R. Yosa): The Pasuk states (Vayikra 12, 3), "And on the 8th day he shall circumcise''. If he transgresses and refrained from circumcising his son, (has he transgressed Bal Te'acher)?

Answer (R. Yosa): The Pasuk states (Devarim 23, 22), "When you shall make a vow to Hash-m, your G-d, you shall not delay to pay it''. This refers to something that is possible to repay; if not, the prohibition does not apply.

The Pasuk states "you shall not delay to pay it'' - nor its replacement, as the Beraisa teaches - the Pasuk states (Vayikra 17, 4), "and he did not bring it to the entrance of the Tent of Meeting'' - nor its replacement.

R. Yona: Levi ben Sisi explained it in front of Rebbi - When a person said "I am obligating myself to bring an Olah'' and 3 festivals passed; if he brought a different animal and sacrificed that immediately, I would say that he is exempt from the first obligation. Therefore, the Torah must write "you shall not delay to pay it'' - nor its replacement.

Rejection (R. Yosa): If he would say, "I am obligating myself'' - would he transgress immediately?! Rather, he said "This [animal] is an Olah'', two festivals passed and he brought a different animal. However, he did not bring it immediately and the 3rd festival passed. I would say that it should combine with its replacement to make a total of 3 festivals. Therefore, the Pasuk must write "you shall not delay to pay it'' - not (combined together with) its replacement.
