Numbers 30:13-16

13Any vow and any binding oath to afflict herself, her husband may establish, or her husband may make void.

14But if her husband says nothing to her from day to day, then he establishes all her vows or all her pledges that are upon her. He has established them, because he said nothing to her on the day that he heard of them.

15But if he makes them null and void after he has heard of them, then he shall bear her iniquity."

16These are the statutes that the Lord commanded Moses about a man and his wife and about a father and his daughter while she is in her youth within her father's house.
