Numbers 30:4-9

4and her father hears about her vow or pledge but says nothing to her, then all her vows and every pledge by which she obligated herself will stand.

5But if her father forbids her when he hears about it, none of her vows or the pledges by which she obligated herself will stand; the Lord will release her because her father has forbidden her.

6“If she marries after she makes a vow or after her lips utter a rash promise by which she obligates herself

7and her husband hears about it but says nothing to her, then her vows or the pledges by which she obligated herself will stand.

8But if her husband 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.

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