Numbers 30:5-7

New Century Version

⁵ But if her father hears about the promise or pledge and does not allow it, then the promise or pledge does not have to be kept. Her father would not allow it, so the Lord will free her from her promise.

⁶ “If a woman makes a pledge or a careless promise and then gets married, ⁷ and if her husband hears about it and says nothing, she must keep her promise or the pledge she made.
