Beth Shammai says: something consecrated in error is consecrated; But Beth Hillel says: it is not consecrated. How is this so? If someone says, “The black bull that leaves my house first shall be consecrated,” and a white one comes out, Beth Shammai says: it is consecrated, But Beth Hillel says: it is not consecrated.

[If he says,] “The gold denar that comes into my hand first shall be consecrated”, and a silver denar came to his hand: Beth Shammai says: it is consecrated, Beth Hillel says: it is not consecrated. [If he says,] “The cask of wine that comes into may hand first shall be consecrated,” and a cask of oil came into his hand: Beth Shammai says: it is consecrated, Beth Hillel says: it is not consecrated.

If a man vowed to be a nazirite and then asked a sage [to be released from his vow] but [the sage] bound him [to his vow] he counts [the naziriteship] from the time that the vow was made. If he asked a sage [to be released from his vow] and he released him, if he had an animal set aside [for a sacrifice], it goes forth to pasture with [the rest of] the herd. Beth Hillel said to Beth Shammai: do you not admit that here where the consecration is in error, [the animal] goes forth to pasture with the herd? Beth Shammai said to them: do you not admit that if a man in error calls the ninth [animal], the tenth, or the tenth the ninth, or the eleventh the tenth, each is consecrated? Beth Hillel said to them: it is not the staff that makes these consecrated. For suppose that by mistake he placed the staff upon the eighth or upon the twelfth, would this have any effect? Rather Scripture which has consecrated the tenth, has also declared consecrated the ninth and the eleventh.

If one vowed to be a nazirite and went to bring his animal [for the sacrifice] and found that it had been stolen: If he had taken the nazirite vow before his animal was stolen, he is [still] a nazirite. But if he had taken the nazirite vow after his animal was stolen, he is not a nazirite. It was this mistake that Nahum the Mede made. When nazirites arrived [in Jerusalem] from the Diaspora and found the Temple destroyed, Nahum the Mede said to them, “Had you known that the Temple would be destroyed, would you have become nazirites?” They answered, no, and Nahum the Mede released them [from their vow]. When the matter came before the sages they said to him: whoever vowed a nazirite vow before the destruction of the Temple is a nazirite, but if after the destruction of the temple, he is not a nazirite.

If [people] were walking along the road and [saw] someone coming towards them, and one said, “Behold, I am a nazirite if it is so-and-so,” and the other said, “Behold, I am a nazirite if it is not so-and-so,” [and a third said,] “Behold I am a nazirite if one of you is a nazirite,” [and a fourth said, “Behold I am a nazirite] if neither of you is a nazirite,” [and a fifth said, “Behold I am a nazirite] if both of you are nazirites,” [and a sixth said, “Behold I am a nazirite] if all of you are nazirites”: Beth Shammai says: all of them are nazirites. Beth Hillel says only those whose words were [not] fulfilled are nazirites. Rabbi Tarfon says: not one of them is a nazirite.

If [the person approaching] turned around suddenly [without being identified], he is not a nazirite. Rabbi Shimon says: he should say, “If it was as I said, behold I am a nazirite by obligation; and if not, behold I am a voluntary nazirite.”
