(Beraisa): In the days of Shimon ben Shetach, 300 Nezirim ascended [to Yerushalayim, without money for Korbanos]. He found a Pesach (reason to consider the vow to be a Nazir a mistake, and permitted them) for 150, and for 150, he did not find;

He came to King Yanai, and said 'there are 300 Nezirim here. They need 900 Korbanos (every Nazir brings three) - you give half from your [of the, and I [will give] half from mine.' (NICHMAD L'MAR'EH, citing SEFER HA'BAHIR - Shimon ben Shetach wanted to help Yanai atone for wanting to make himself Kohen Gadol and killing the Chachamim)

[Yanai] sent 450. He heard Leshon ha'Ra that [Shimon ben Shetach] did not give anything from his own. King Yanai heard, and was angry. Shimon ben Shetach fled;

Days later, great people from the Persian kingdom came and said to [Yanai] 'we remember that there is an elder here who said matters of Chachmah!' He told them the episode; they said, send and bring him.

He sent, and gave his word [that he will not harm him]. He came and sat between the king and queen.

Yanai: Why did you jest with me (say that you will give half from yours)?!

Shimon ben Shetach: I did not jest with you! You [gave] with your money, and I gave with my Torah - "Ki b'Tzel ha'Chachmah b'Tzel ha'Kesef"!

Yanai: Why did you flee?

Shimon ben Shetach: I heard that you were angry at me. I wanted to fulfill on myself "Chavi Chim'at Rega Ad Ya'avor Za'am." Yanai applied to him "v'Yisron Da'as ha'Chachmah Techayeh Ve'aleha."

Yanai: Why did you sit between the king and queen?

Shimon ben Shetach: It is written in Sefer Ben Sira 'Salseleha u'Sromemecha u'Vein Negidim Toshivecha."

Yanai: Give the cup to him, to bless [Birkas ha'Mazon for us]. They gave the cup to him, and he said "blessed is He from Whom Yanai and his friends ate."

Yanai: Are you so stubborn [to still mock me]?!

Shimon ben Shetach: (I did not eat.) What can I say - 'for the food that we did not eat'?!

Yanai: Give to him [to eat]! He ate, and said 'let us bless for the food that we ate.'

(R. Yochanan): [The other Tana'im] argue with Shimon ben Shetach.

(R. Yirmeyah): They argued [only] about the first matter (he was prepared to bless even though he did not eat at all, just he would say 'from Whom Yanai and his friends ate').

(R. Ba): They argued about the second. (Even though he did not eat bread, he said Birkas ha'Mazon.)

Contradiction: R. Yirmeyah contradicts himself! There, he was unsure [whether or not one who ate vegetables can bless to exempt those who ate bread], and here it was clear to him [that all agree that he can]!

Answer: He was unsure according to Rabanan (if he only joins to a Zimun, or he can even be Motzi the others); it was clear to him according to R. Shimon ben Gamliel;

(Beraisa - R. Shimon ben Gamliel): If he ascended, reclined and ate with them, even if he did not eat a k'Zayis of grain, we are Mezamen [with him].

Chachamim's (i.e. the following Amora'im's) opinion - R. Yakov bar Acha citing R. Yochanan said, we are never Mezamen with him, until he eats a k'Zayis of grain. (We explained this like MAHARA FULDA Brachos 7:2.)

Question (Beraisa): If two ate bread and one ate vegetables, we are Mezamen.

Answer: The Beraisa is like R. Shimon ben Gamliel.

(Mishnah): Six men (Yosef, Binyamin...) were walking on the road; they saw a man walking towards them.

Yosef: I am a Nazir if the man approaching us is Ploni.

Binyamin: I am a Nazir if it is not him.

Levi: I am a Nazir if one of you (Yosef and Binyamin) is a Nazir,'

Yehudah: [I am a Nazir] if one of you (Yosef and Binyamin) is not a Nazir,'

Yisachar: I am a Nazir if both of you are Nezirim.

Zevulun: I am a Nazir if all [five] of you are Nezirim.

Beis Shamai says, all [six] of them are Nezirim.

Beis Hillel say, only those whose words were not fulfilled are Nezirim;

R. Tarfon says, not one of them is a Nazir.

If the approaching man turned back (and we will never know if it was Ploni), he is not a Nazir;

R. Shimon says, each says 'if I was correct, I am a Nazir from my previous acceptance. If I was wrong, I now accept Nezirus on myself.'

[Yosef] saw a Koy. (Chachamim were unsure if it is a Chayah or Beheimah, i.e. a wild or domestic animal). He said 'I am a Nazir if this is a Chayah;

Binyamin: I am a Nazir if it is not a Chayah;

Levi: I am a Nazir if it is a Beheimah;

Yehudah: I am a Nazir if it is not a Beheimah;

Yisachar: I am a Nazir if this is a Chayah and a Beheimah;

Zevulun: I am a Nazir if this is not a Chayah nor a Beheimah;

Gad: I am a Nazir if one of (the six of) you is a Nazir;

Asher: I am a Nazir if one of you is not a Nazir;

Dan: I am a Nazir if all of you are Nezirim.

NOTE: TOSFOS (33a DH Ra'ah) says that the text should not say 'both of you' (for it is not clear at all which two he refers). However, it is clear below that 10 people accepted Nezirus conditionally. Therefore, we adopt the text of SEFER NIR.

Naftoli: I am a Nazir if all of you are not Nezirim.

All of them are Nezirim.

(Gemara): The Mishnah means, [Beis Hillel say that] one whose words were fulfilled [is a Nazir. To prove their opinions, each man said, if it is unlike I hold, I am a Nazir;] this is a reversed expression, [like a woman who says] 'if not, she (a euphemism for herself) should bury her son.'

(Beraisa - R. Yehudah citing R. Tarfon): Not one of them is a Nazir, for Nezirus is only with warning (if one says that he did not intend to accept Nezirus, for he was sure, he is not a Nazir, unless two witnesses warned him and said that he errs - ALEI TAMAR).

(Our Mishnah taught that if the approaching man turned back, he is not a Nazir.) This is like R. Yehudah himself, who says that Safek Nezirus is permitted. (It is unlike he said in the name of R. Tarfon, for R. Tarfon exempts even if the man did not turn back.)

Question: What is the case?

If [Yosef] said [the man is] Reuven, and Binyamin said 'it is not Reuven', no matter what you will say, [Levi is a Nazir]! If it is Reuven, [Levi] is a Nazir (for Yosef is a Nazir). If it is Shimon (i.e. not Reuven), [Levi] is a Nazir (for Binyamin is a Nazir! SEFER NIR - now, we do not obligate Yosef or Binyamin to be a Nazir, due to Safek. However, before the man turned back, one was 'destined' to be a Nazir, so Levi became a Nazir. His Nezirus is not uprooted when the man turned back.)

Answer: Rather, the case is, [Yosef] said he is Reuven, and Binyamin said he is Shimon. The man turned back; [perhaps] he is not Reuven and not Shimon, and neither is a Nazir.

(The Seifa says that all of them are Nezirim.) This is like R. Shimon, who says that [we are stringent about Safek Nezirus, but] he does not bring a Korban unless he stipulates ['if I was correct, I am a Nazir from my previous acceptance. If I was wrong, I now accept Nezirus on myself.' We explained this like R. MEIR SIMCHAH.]

(Beraisa): All of them count nine Neziriyos (i.e. there are nine of them).

Question: There are 10!

Answer: It is impossible that the words of one of them were not fulfilled (so there are only nine Nezirim).

(R. Yosa): Our Mishnah is like Beis Shamai. Beis Shamai say that mistaken Hekdesh is Hekdesh (and mistake Nezirus is Nezirus, so all 10 are Nezirim).
