(Mishnah): If one said 'I will be a Nazir when I have a son. I am a Nazir 100 days', and he had a son within 70 days of saying this, he does not lose any of the days counted. (After finishing and shaving for Nezirus Beno, he completes the days remaining for his Nezirus.)

If he had a son after 70 days, he cancels [the excess above] 70, since Tiglachas cannot be [on] less than 30 days [growth of hair. After completing Nezirus Beno, he must count another 30 days in order to shave for his Nezirus. Effectively, only 70 days before the birth counted for his Nezirus.]

(Gemara) Question: Obviously, the end of the day [on which his son was born, and he observed Nezirus Beno from then until the end of the day] counts like the entire day. Does the beginning of the day count like the entire day [for his own Nezirus]?

Answer: Do we not learn from our Mishnah? If he had a son after 70 days, he cancels [the excess above] 70. Is this not even [on day 71, and the excess above 70 is] part [of that day before the birth]?! This teaches that the beginning of the day counts like the entire day.

If [a son] was born on day 80, he cancels 10 days. If he was born on day 90, he cancels 20 days.

[When a son was born on day 90, and] he finished Nezirus Beno and comes to complete his Nezirus, if he became Tamei within the first 10 days, he cancels everything [for his Nezirus, for it was within the 100 days that he counted for it];

[If he became Tamei] in the last 20 days [that he must observe after 100, in order to shave 30 days growth of hair], R. Ba citing Rav and R. Yochanan, both of them say that he cancels 30 [after Tiglachas Tum'ah, he must observe after 30, for Tiglachas Taharah.) R. Shmuel says, he cancels only seven.

Question (Shmuel bar Ba, in front of R. Yosa): Does R. Yochanan hold that Stiras Ta'ar (after completing the days he vowed, during extra days he must count in order to shave 30 days of hair) is proper Stirah?

Answer (R. Ze'ira): Yes! R. Yochanan holds that Stiras Ta'ar is like proper Stirah.

Question: [If he became Tamei in the last 20 days,] why does [R. Yochanan] say that he cancels 30? He should cancel everything!

Answer (R. Avin bar Chiyah, in front of R. Ze'ira): [It is as if] he became Tamei on a day when it is proper to bring a Korban (i.e. day 101, after finishing the days he vowed. Below (3:4), Chachamim say that this cancels only 30 days.)

Question: Exert yourself [and you will find the answer]! If he became Tamei at night, it is not proper to bring a Korban then!

Answer: It is proper [to bring a Korban any time after 100], just night causes [that he cannot offer it now].

Question: Exert yourself [and you will find the answer]! If he became Tamei on Shabbos, it is not proper to bring a Korban then!

Answer: It is proper, just Shabbos causes [that he cannot offer it now. We explained this like OHR SOMAYACH, Hilchos Nezirus 4:3.]

Question: If he finished his Nezirus and was not Megale'ach before [a son] was born on Shabbos, he is not proper to bring a Korban! (This should be as if he was born before he finished his Nezirus!)

Note: Perhaps this question and answer really belong after the coming teaching about one who finished his Nezirus and was not Megale'ach before the son was born. Perhaps it was taught here, to put it together with the other cases of 'it is proper, just Shabbos causes.' (PF)

Answer: It is proper [to bring a Korban then], just Shabbos causes (that we cannot offer it now).

If he finished his Nezirus and was not Megale'ach before the son was born, he is Megale'ach once for both [Neziriyos].

If he separated his Korbanos and was not Megale'ach before the son was born - there (in Bavel), they say that he is Megale'ach once for both.

(R. Yochanan): He is Megale'ach, and returns and is Megale'ach again.

Question (against R. Yochanan - Beraisa) Question: They asked R. Shimon ben Yochai - if one was a Nazir and Metzora, may he shave once and it will count for his Nezirus and his Tzara'as?

Answer (R. Shimon): If [a Nazir] shaved in order to remove the hair, and [a Metzora] shaved in order to remove the hair, you would say properly. However, a Nazir shaves to remove hair, and a Metzora shaves to grow hair (i.e. in order to shave again. Therefore, one shaving cannot count for both.)

Question (to R. Shimon): The shaving of Yemei Gamro (when the Tzara'as went away) should not count [for Tiglachas Nazir, since it is to grow hair], but the shaving of Yemei Sifro (the second time a Metzora shaves, six days after the first shaving) should count [for Tiglachas Nazir], since both of them shave to remove hair!

Answer (R. Shimon): If [a Nazir] shaved before Zerikas Dam [of his Korbanos] and [a Metzora] shaved before Zerikas Dam, you would say properly. However, a Nazir shaves after Zerikas Dam hair, and a Metzora shaves before Zerikas Dam. (Therefore, one shaving cannot count for both.)

Question (to R. Shimon): Even we say that [Tiglachas Yemei Sifro] should not count for [Tiglachas Nazir] Tahor, but it should count for [Tiglachas Nazir] Tamei (both of them are before Zerikas Dam)!

Answer (R. Shimon): If [a Nazir Tamei] shaved before Tevilah and [a Metzora after Yemei Sifro] shaved before Tevilah, you would say properly. However, a Nazir shaves after Tevilah, and a Metzora shaves before Tevilah!

Talmidim: Establish the matter as follows. [Tiglachas] Yemei Gamro does not count [for Tiglachas Nazir], and [Tiglachas] Yemei Sifro does not count, not for a [Nazir] Tahor and not for a Tamei - this is all for a Nazir Metzora. However, if he was a Nazir and a Nazir, one Tiglachas should count for both of them (they are the same)!

Question: How does R. Yochanan answer this?

Answer: He holds that [the other Tana'im] argue with R. Shimon ben Yochai.
