Numbers 30:12-14

12But if her husband actually annuls them on the day he hears them, then no utterance from her lips concerning her vows or the obligation she put on herself shall remain valid; her husband has annulled them, and the Lord will 1forgive 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 in fact says nothing to her from day to day, then he confirms all her vows or all her binding obligations which are on her; he has confirmed them, because he said nothing to her on the day he heard them.
