Numbers 30:3-5

3“If a young woman who is still living in her father’s house makes a vow to the Lord or places herself under an obligation,

4and her father hears of her vow or the obligation to which she has pledged herself, and her father remains silent about her, then all her vows will stand, and every obligation to which she has pledged herself will stand.

5But if her father overrules her when he hears about it, then none of her vows or her obligations which she has pledged for herself will stand. And the Lord will release her from it, because her father overruled her.
