Numbers 30:14

Every vow, and every binding oath to afflict her soul, her husband shall confirm it to her, or her husband shall cancel it.

But if her husband altogether hold his peace at her from day to day; then he establisheth all her vows, or all her bonds, which are upon her: he confirmeth them, because he held his peace at her in the day that he heard them.

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