Bible Verses About Vows: Of children void without the consent of parents

If any man make a vow to the Lord, or bind himself by an oath: he shall not make his word void but shall fulfil all that he promised.

If a woman vow any thing, and bind herself by an oath, being in her father's house, and but yet a girl in age: if her father knew the vow that she hath promised, and the oath wherewith she hath bound her soul, and held his peace, she shall be bound by the vow:

Whatsoever she promised and swore, she shall fulfil in deed.
