Numbers 30:7-9

Evangelical Heritage Version

⁷ and her husband hears about it but says nothing to her on the same day that he hears about it, then her vows will stand, and her obligations which she has undertaken will be binding. ⁸ But if her husband forbids her on the same day that he hears about it, he will nullify her vow which obligates her and her responsibility for the things she spoke rashly. The Lord will forgive her.

⁹ But the vow of a widow or a divorced woman, every obligation which she put herself under, will be binding on her.
