Numbers 30:8-12

8But if her husband prohibits her when he hears about it, he will cancel her vow that is binding or the rash commitment she herself made, and the Lord will release her.

9“Every vow a widow or divorced woman puts herself under is binding on her.

10“If a woman in her husband’s house has made a vow or put herself under an obligation with an oath,

11and her husband hears about it, says nothing to her, and does not prohibit her, all her vows are binding, and every obligation she put herself under is binding.

12But if her husband cancels them on the day he hears about it, nothing that came from her lips, whether her vows or her obligation, is binding. Her husband has canceled them, and the Lord will release her.
