Numbers 30:1-8

1 And Moses spake unto the heads of the tribes of the children of Israel, saying, This is the thing which Jehovah hath commanded.
2 When a man voweth a vow unto Jehovah, or sweareth an oath to bind his soul with a bond, he shall not break his word; he shall do according to all that proceedeth out of his mouth.
3 Also when a woman voweth a vow unto Jehovah, and bindeth herself by a bond, being in her father's house, in her youth,
4 and her father heareth her vow, and her bond wherewith she hath bound her soul, and her father holdeth his peace at her; then all her vows shall stand, and every bond wherewith she hath bound her soul shall stand.
5 But if her father disallow her in the day that he heareth, none of her vows, or of her bonds wherewith she hath bound her soul, shall stand: and Jehovah will forgive her, because her father disallowed her.
6 And if she be [married] to a husband, while her vows are upon her, or the rash utterance of her lips, wherewith she hath bound her soul,
7 and her husband hear it, and hold his peace at her in the day that he heareth it; then her vows shall stand, and her bonds wherewith she hath bound her soul shall stand.
8 But if her husband disallow her in the day that he heareth it, then he shall make void her vow which is upon her, and the rash utterance of her lips, wherewith she hath bound her soul: and Jehovah will forgive her.
