If one says, “This cow is saying ‘Behold, I am a nazirite if I get up,” or “This door is saying ‘Behold, I am a nazirite if I open”: Bet Shammai says: he is a nazirite, But Bet Hillel says: he is not a nazirite. Rabbi Judah said: even though Beth Shammai did say [that his formula is effective] they meant only one who says, “This cow is [forbidden] to me, as is a sacrifice if it gets up.”

If they mixed for him a cup of wine, and he said, “Behold, I am a nazirite in regard to it,” he becomes a nazirite. It once happened that a woman was intoxicated and they mixed for her a cup of wine and she said, “Behold, I am a nazirite in regard to it.” The sages ruled that she only meant to forbid it to herself as a sacrifice.

[If one says,] “Behold, I am a nazirite, on condition that I can drink wine, or can have contact with the dead”, he becomes a nazirite, and all these things are forbidden him. [If he says,] “I knew that there is such a thing as naziriteship but I did not know that a nazirite is forbidden to drink wine”, he is bound [to his vow]. Rabbi Shimon releases him. [If he says,] “I knew that a nazirite is forbidden to drink wine, but I imagined that the sages would give me permission, since I cannot do without wine”, or “since [my profession] is to bury the dead”, he is released. Rabbi Shimon binds him [to his vow].

[If one says,] “Behold, I am a nazirite and I take it upon myself to bring the hair offering of another nazirite”, and his friend heard and said “I too, and I take it upon myself to bring the hair offering of another nazirite”, then, if they are clever they will bring the other’s hair offering; otherwise they must bring hair offerings on behalf of other nazirites.

[If one says,] “I take it upon myself to bring the hair offering of half of another nazirite,” and his friend heard and said, “I too take it upon myself to bring the hair offering of half of another nazirite,” –, this one brings a full hair offering and this one brings a full hair offering, the words of Rabbi Meir. But the Sages say: each brings half a hair offering.

[If one says,] “Behold, I am a nazirite when I shall have a son,” and son is born to him, he becomes a nazirite. If the child is a daughter, or a tumtum, or an hermaphrodite, he does not become a nazirite. If he said, “When I shall have a child,” then even if it is a daughter, or a tumtum, or an hermaphrodite, he becomes a nazirite.

If his wife miscarries, he does not become a nazirite. Rabbi Shimon says: [in this case] he should say, “If it was a viable child, behold, I am a nazirite from obligation; otherwise behold, I am a voluntary nazirite.” If [his wife] later bears a child, he then becomes a nazirite. Rabbi Shimon says: he should say, “If the first was a viable child, the first [naziriteship] was obligatory, and this one is voluntary; otherwise, the first one was voluntary, and the present one is obligatory.”

[If one says,] “Behold, I am a nazirite [now] and a nazirite when I shall have a son”, and begins to count his own [naziriteship] and then a son is born to him, he completes his own [naziriteship] and then counts the one on account of his son. [If one says,] “Behold, I am a nazirite when I shall have a son, and a nazirite [on my own account]”, and begins to count his own [naziriteship] and then a son is born to him, he interrupts his own [naziriteship], counts the one on account of his son, and then complete his own.

[If one says] “Behold, I am a nazirite when I shall have a son, and I will be a nazirite for one hundred days [on my own account],”: if a son was born to him before the expiration of seventy days, he loses none of this period; but if after seventy days, it voids [anything over the] seventy days, since there can be no shaving for a period of less than thirty days.
