Numbers 30:7-9

New International Version

⁷ and her husband hears about it but says nothing to her, then her vows or the pledges by which she obligated herself will stand. ⁸ But if her husband^(A) forbids her when he hears about it, he nullifies the vow that obligates her or the rash promise by which she obligates herself, and the Lord will release her.^(B)

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