Numbers 30:9-16 - Vows Made By Widows
9 "Everything that a widow or a divorced woman pledges herself to fulfill are to be binding on her.
10 If, while she had been living in her late or former husband's house, she makes a vow or a promise that binds her with an oath, 11 and her husband hears it but remains silent, not disallowing it, then all her vows are to stand, along with every obligation that she has pledged to fulfill. 12 But if her husband disallowed them the very day that he heard her, everything that she spoke relating to her vows and her obligation to herself are not to stand, because her husband revoked them. The LORD will forgive her. 13 Her husband may confirm or revoke every vow and binding obligation that afflicts her. 14 But if her husband remains silent about her from day to day, then he has affirmed all her vows or obligations that she has obligated herself to fulfill. He has affirmed them because he remained silent from the day he heard her vows. 15 But if he nullified them after he had heard, then he will be responsible for any resulting iniquity."
16 These are the statutes that the LORD commanded Moses concerning a man and his wife and concerning a father and his young daughter while she still lives in her father's house.
