Numbers 30:13-16

13The husband may let his wife do what she promised to do, or he may refuse.

14If the husband does not say anything for many days about the promise, the woman must do what she promised.

15The husband may wait for many days after he hears about his wife's promise. If he then refuses to let her do what she promised, he will be guilty. God will punish him instead of his wife.’

16Those are the rules that the Lord gave to Moses. They say what must happen when husbands, wives or young women who still live at home make a promise to the Lord.
