Numbers 30:5-7

Living Bible

⁵ But if her father refuses to let her make the vow, or feels that the penalties she has agreed to are too harsh, then her promise will automatically become invalid. Her father must state his disagreement on the first day he hears about it; and then Jehovah will forgive her because her father would not let her do it.

⁶ “If she takes a vow or makes a foolish pledge, and later marries, ⁷ and her husband learns of her vow and says nothing on the day he hears of it, her vow shall stand.
