Numbers 30:9-11

New International Version

⁹ “Any vow or obligation taken by a widow or divorced woman will be binding on her.

¹⁰ “If a woman living with her husband makes a vow or obligates herself by a pledge under oath ¹¹ and her husband hears about it but says nothing to her and does not forbid her, then all her vows or the pledges by which she obligated herself will stand.
