פירוש על נזיר 4:2

הריני נזיר ואת ואמרה אמן מיפר את שלה – and exactly when he said it to her in the language of a question, meaning to say, “and you, what do you say? Will you become a Nazirite like me or not?” Then he is enabled to annul [her vow], but if he said, “I am becoming a Nazirite, and you,” as a statement (i.e., not as a question), and she answered, “Amen,” he is not able to annul her vow for it exists for her.

Introduction This mishnah continues to deal with when a husband can annul his wife’s nazirite vow.

[If he says in conversation with his wife,] “Behold, I am a nazirite. What about you?” and she answers “Amen,” he can annul her vow, but his own remains binding. In this case, the husband has not confirmed his wife’s vow, but merely asked her if she would like to be a nazirite. The question itself cannot be construed as a confirmation of her vow because she has not yet vowed. Since he never confirmed her vow, he can annul it.

[But if she should say,] “Behold, I am a nazirite, what about you?” and he answers, “Amen,” he cannot annul her vow. However, if she says that she is a nazirite and then asks him if he too would like to be a nazirite and he says “Amen”, he has not only taken a nazirite vow, he has also confirmed her vow. By doing so he has relinquished the right to later annul her vow.
