Numbers 30:7-9

Good News Translation

⁷ she must do everything that she vowed or promised unless her husband raises an objection when he hears about it. ⁸ But if her husband forbids her to fulfill the vow when he hears about it, she is not required to keep it. The Lord will forgive her.

⁹ A widow or a divorced woman must keep every vow she makes and every promise to abstain from something.
