Numbers 30:12-14

12But if her husband indeed annuls them on the day he hears them, then whatever proceeds out of her lips concerning her vows or concerning the obligation of herself shall not stand; her husband has annulled them, and the Lord will forgive her.

13“Every vow and every binding oath to humble herself, her husband may confirm it or her husband may annul it. 14But if her husband indeed says nothing to her from day to day, then he confirms all her vows or all her obligations which are on her; he has confirmed them, because he said nothing to her on the day he heard them.
