Numbers 30:9-11

New American Standard Bible

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. ¹⁰ However, if a married woman vowed in her husband’s house, or put herself under a binding obligation with an oath, ¹¹ and 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.
