Numbers 30:8-12

8But if her husband should hear about it and on the day he hears it he forbids it, he thereby nullifies her vow and her rash promise by which her lips have obligated her, and Adonai will forgive her.

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

10If in her husband’s house she vowed or obligated herself by pledge under oath,

11and her husband should hear it and say nothing to her, not forbidding her, all her vows and every pledge by which she has obligated herself will stand.

12But if her husband should nullify them on the day when he hears of them, nothing from her lips, whether vow or pledge, will stand. Her husband has nullified them and Adonai will forgive her.
