Numbers 30:9-11

English Standard Version

⁹ (But any vow of a widow or of a divorced woman, anything by which she has bound herself, shall stand against her.) ¹⁰ And if she vowed in her husband's house or bound herself by a pledge with an oath, ¹¹ and her husband heard of it and said nothing to her and did not oppose her, then all her vows shall stand, and every pledge by which she bound herself shall stand.
