Numbers 30:8

and her husband should hear, and hold his peace at her in the day in which he should hear, then thus shall all her vows be binding, and her obligations, which she has contracted upon her soul shall stand.

But if her husband disallowed her on the day that he heard it; then he shall make her vow which she vowed, and that which she uttered with her lips, wherewith she bound her soul, of none effect: and the Lord shall forgive her.

But if her husband forbids her in the day that he hears it, then he makes void her vow which is on her and the rash utterance of her lips, with which she has bound her soul. Yahweh will forgive her.
