Numbers 30:12-14

12But if her husband makes them null and void on the day that he hears them, then whatever proceeds out of her lips concerning her vows or concerning her pledge of herself shall not stand. Her husband has made them void, and the Lord will forgive her.

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.
