Midrasz do Liczb 30:7

(Bamidbar 30:7) "And if she be to a man, and her vows be upon her": This refers to one who is betrothed. These are the words of R. Yoshiyah. R. Yonathan says: In either case, (i.e., either betrothed or wed) Scripture comes to make a distinction, viz.: As long as she is in her father's house, her father and her husband (jointly) annul her vows. If she is wed, her father does not annul her vows. "and her vows be upon her": the vows that "came along" with her from her father's house to her husband's house. Whence do I derive (the same for) vows that she made on his (her husband's) domain? — Do you ask? It follows a fortiori, viz.: If he annuls vows that she vowed not in his domain, how much more so vows that she made in his domain! Variantly: "and her vows be upon her": (Can the husband annul only) vows which were never confirmed (in her father's house) or even vows which were confirmed there? It follows (inductively), viz.: The husband annuls and the father annuls. Just as the father annuls only vows which were never confirmed or annulled, so, the husband. And, furthermore, it follows a fortiori, viz.: If the father, who has an exclusive prerogative (over his daughter's vows) can annul only vows which were never confirmed, how much more so, the husband, who does not have such a prerogative! — No, this may be true of the father, who does not annul in her maturity — wherefore he annuls only vows which were never confirmed, as opposed to the husband, who does annul (the vows of her) maturity — wherefore he can annul every vow, (even those confirmed in her father's house)? Not having succeeded with (pure) ratiocination, we must revert to Scripture, viz.: "These are the statutes which the L-rd commanded Moses, between a man and his wife, between a father and his daughter. Scripture likens the husband to the father, viz.: Just as the father can annul only those vows which were never confirmed, so, the husband. "or the utterance (mivta) of her lips": "bitui" (like "mivta") connotes an oath, as in (Vayikra 5:4) "Or if a soul swear 'levatei' with his lips."
