Numbers 30:10-15

However, if she vowed in her husband’s house, or bound herself by an obligation with an oath, and her husband heard it, but said nothing to her and did not forbid her, then all her vows shall stand and every obligation by which she bound herself shall stand. But 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. “Every vow and every binding oath to humble herself, her husband may confirm it or her husband may annul it. But 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. But if he indeed annuls them after he has heard them, then he shall bear her guilt.”
