Moses spoke to the heads of the Israelite tribes, saying: This is what the Lord has commanded:
If a man makes a vow to the Lord or takes an oath imposing an obligation on himself, he shall not break his pledge; he must carry out all that has crossed his lips.
If a woman makes a vow to the Lord or assumes an obligation while still in her father's household by reason of her youth, and her father learns of her vow or her self-imposed obligation and offers no objection, all her vows shall stand and every self-imposed obligation shall stand. But if her father restrains her on the day he finds out, none of her vows or self-imposed obligations shall stand; and the Lord will forgive her, since her father restrained her.
If she should marry while her vow or the commitment to which she bound herself is still in force, and her husband learns of it and offers no objection on the day he finds out, her vows shall stand and her self-imposed obligations shall stand. But if her husband restrains her on the day that he learns of it, he thereby annuls her vow which was in force or the commitment to which she bound herself; and the Lord will forgive her. The vow of a widow or of a divorced woman, however, whatever she has imposed on herself, shall be binding upon her. So, too, if, while in her husband's household, she makes a vow or imposes an obligation on herself by oath, and her husband learns of it, yet offers no objection--thus failing to restrain her--all her vows shall stand and all her self-imposed obligations shall stand. But if her husband does annul them on the day he finds out, then nothing that has crossed her lips shall stand, whether vows or self-imposed obligations. Her husband has annulled them, and the Lord will forgive her. Every vow and every sworn obligation of self-denial may be upheld by her husband or annulled by her husband. If her husband offers no objection from that day to the next, he has upheld all the vows or obligations she has assumed: he has upheld them by offering no objection on the day he found out. But if he annuls them after [the day] he finds out, he shall bear her guilt.
Those are the laws that the Lord enjoined upon Moses between a man and his wife, and as between a father and his daughter while in her father's household by reason of her youth.
