(Mishnah - Beis Shamai): If one said 'this cow said 'I will be a Nazir if I will get up' or 'this door said 'I will be a Nazir if I will be opened'', he is a Nazir;

Beis Hillel say, he is not a Nazir.

R. Yehudah says, Beis Shamai discuss only one who said 'this cow is a Korban if it will stand.'

(Gemara): If one saw a Nochri pass, and said 'see what this Nochri said - he is (i.e. he accepted to be) a Nazir!' If [we find that indeed the Nochri] said so, since Nochrim do not vow to be Nezirim, [surely the Yisrael said so in order to accept Nezirus].

Question: If [we find that] he did not say so [what is the law]?

Answer: We learn from [our Mishnah]. If one said 'this cow said... Did the cow say anything?! [Rather,] you must say that it is because he said 'Nezirus' with his mouth. And [also] here, [the Yisrael] said 'Nezirus' with his mouth (so he is a Nazir).

If one (Ploni) saw a Yisrael pass, and said 'see what this Yisrael said - he is a Nazir'!' If [we find that] he did not say so, since Yisraelim vow to be Nezirim, [surely Ploni said so in order to accept Nezirus].

Question: If [we find that] he said so - [do we say that] even so, [Ploni accepted to be] like [him, i.e.] a Nazir? Or perhaps [Ploni] merely retells the Yisrael's words (but Ploni did not accept anything? We explained this like PNEI MOSHE.)

Answer: So I say - if one was reading in the Torah, and he mentioned Nazir, is he a Nazir?! (Surely he is not!)

Question: Can a man accept Nezirus in the feminine ('I am a Nezirah')?

Answer: There (in Bavel), they say 'a Nezirah is passing' [about a man. This shows that 'Nezirah' applies to even to a man.]

Question: Can a woman accept Nezirus in the masculine ('I am a Nazir')?

Answer (R. Yosi): The entire [source in Torah for] Nezirus [includes women, and it] is only in the masculine - "Ish Oh Ishah Ki Yafli Lindor Neder [Nazir]"!

Question: [In our Mishnah, do Beis Shamai say that he is a Nazir - PNEI MOSHE] only if [the cow] gets up, and only if the door opens?

Answer: We learn from the following [Mishnah. If six men saw a man, and each accepted Nezirus contingent on his identity, or contingent on whether or not these acceptances took effect,] Beis Shamai says, all of them are Nezirim (even though their conditions of acceptance are contradictory, for mistaken Hekdesh is Hekdesh). Beis Hillel say, only those whose words were not fulfilled are Nezirim.]

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.' (We explained like SEFER NIR.)

Conclusion: Even if the cow did not get up, even if the door did not open, Beis Shamai says that he is Nadur [a vow forbids him to eat the cow] and a Nazir (like at the end of Halachah 1). Beis Hillel say, he is not Nadur and not a Nazir.
