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.

Commentary on Numbers 30:3-16
(Read Numbers 30:3-16)
Two cases of vows are determined. The case of a daughter in her father's house. When her vow comes to his knowledge, it is in his power either to confirm it or do it away. The law is plain in the case of a wife. If her husband allows her vow, though only by silence, it stands. If he disallows it, her obligation to her husband takes place of it; for to him she ought to be in subjection, as unto the Lord. The Divine law consults the good order of families. It is fit that every man should bear rule in his own house, and have his wife and children in subjection; rather than that this great rule should be broken, or any encouragement be given to inferior relations to break those bonds asunder, God releases the obligation even of a solemn vow. So much does religion secure the welfare of all societies; and in it the families of the earth have a blessing.
