If a woman also, &c.— Two cases are next put, of persons who are under authority, and not entirely at their own disposal; and, by a very equitable law, it is determined, that their vows shall not stand, if disallowed by those under whose authority they are. The same law, founded in natural reason, extends to all under authority; nobody who is subject to another having any right to dispose of those things which are in that other's power. Puffendorf judiciously remarks, that this power was fitly reserved to parents, &c. lest women, in their imprudent years, should ruin themselves by vowing more than their fortunes could bear, and lest the paternal estate should be burdened by such vows. See his Law of Nat. and Nations, book 6: ch. 2 sect. 11.
Numbers 30:3-8
3 If a woman also vow a vow unto the LORD, and bind herself by a bond, being in her father's house in her youth;
4 And her father hear her vow, and her bond wherewith she hath bound her soul, and her father shall hold 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; not any of her vows, or of her bonds wherewith she hath bound her soul, shall stand: and the LORD shall forgive her, because her father disallowed her.
6 And if she had at all an husband, when she vowed,b or uttered ought out of her lips, wherewith she bound her soul;
7 And her husband heard it, and held his peace at her in the day that he heard it: then her vows shall stand, and her bonds wherewith she bound her soul shall stand.
8 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.
