Numbers 30:6-8

Living Bible

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. ⁸ But if her husband refuses to accept her vow or foolish pledge, his disagreement makes it void, and Jehovah will forgive her.
