Numbers 30:6-8

Revised Standard Version

⁶ And if she is married to a husband, while under her vows or any thoughtless utterance of her lips by which she has bound herself, ⁷ and her husband hears of it, and says nothing to her on the day that he hears; then her vows shall stand, and her pledges by which she has bound herself shall stand. ⁸ But if, on the day that her husband comes to hear of it, he expresses disapproval, then he shall make void her vow which was on her, and the thoughtless utterance of her lips, by which she bound herself; and the Lord will forgive her.
