Daf 79b
GEMARA. [He can annul] only vows of self-denial, but not if they involve no self-denial? But it was taught: Between a man and his wife, between thee father and his daughter: this teaches that a husband can annul vows which [affect the relationship] between himself and his wife? — I will tell you: He can annul both; but vows of self-denial he can permanently annul; but if they involve no self-denial, annulment is valid only so long as she is under him, but if he divorces her, the vow becomes effective. [This refers however] to matters affecting their mutual relationship but involving no self-denial; but if they involve self-denial, the vow does not become effective. Now, do vows involving no self-denial become effective if he divorces her? But we learnt: R. Johanan b. Nuri said: He must annul it, lest he divorce her and she thereby be forbidden to him. This proves that if he divorces her after first having annulled the vow, the annulment remains valid? — I will tell you: in both cases the annulment stands; but vows of self-denial he can annul in respect of both himself and strangers, whereas if they involve no self-denial, he can annul in respect of himself only, not of others; and it is thus meant: THESE ARE THE VOWS WHICH HE CAN ANNUL in respect of both himself and others, viz., VOWS THAT INVOLVE SELF-DENIAL. 'IF I BATHE.' What does this mean? Shall we say, that she declared, 'Konam be the fruit of the world to me, if I bathe'? then why annul it? Let her not bathe, and so the fruit of the world will not be prohibited to her! Moreover, could R. Jose maintain in this case that THESE ARE NOT VOWS OF SELF-DENIAL: perhaps she bathes, and the fruit of the world become forbidden to her?
