'Nullify' in the Bible

But 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.

"Any vow or sworn obligation that would bring affliction to her, her husband can confirm or nullify.

But if he should nullify them after he has heard them, then he will bear her iniquity."
