Numbers 30:8-12

8But if when her husband hears it he overrules her, then he will nullify the vow she has taken, and whatever she uttered impulsively which she has pledged for herself. And the Lord will release her from it.

9“But every vow of a widow or of a divorced woman which she has pledged for herself will remain intact.

10If she made the vow in her husband’s house or put herself under obligation with an oath,

11and her husband heard about it, but remained silent about her, and did not overrule her, then all her vows will stand, and every obligation which she pledged for herself will stand.

12But if her husband clearly nullifies them when he hears them, then whatever she says by way of vows or obligations will not stand. Her husband has made them void, and the Lord will release her from them.
