Numbers 30:3-5

3“A young girl, who still lives in her father’s house, might make a vow to the Lord that she will do something or swear an oath that she won’t do something.

4If her father says nothing to her when he hears about it, her vow or oath must be kept.

5But if her father objects when he hears about it, her vow or oath doesn’t have to be kept. The Lord will free her ⌞from this vow or oath⌟ because her father objected.
