Numbers 30:9-13

“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.

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

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.

But 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 forgive her.

“Every vow and every binding oath to humble herself, her husband may confirm it or her husband may annul it.
