Numbers 30:8-12

8But if on the day her husband hears of it, he expresses disapproval to her, then he will annul her vow which 1she is under and the impulsive statement of her lips by which she has obligated herself; and the Lord will 2forgive her.

9“But as for the vow of a widow or of a divorced woman, every binding obligation under which she has put herself, shall remain valid against her. 10However, if a married woman vowed in her husband’s house, or put herself under a binding obligation with an oath, 11and her husband heard it, but said nothing to her and did not express disapproval to her, then all her vows shall remain valid and every binding obligation under which she put herself shall remain valid. 12But if her husband actually annuls them on the day he hears them, then no utterance from her lips concerning her vows or the obligation she put on herself shall remain valid; her husband has annulled them, and the Lord will 3forgive her.
