Numbers 30:3-5  Amplified Bible, Classic Edition

³ Also when a woman vows a vow to the Lord and binds herself by a pledge, being in her father’s house in her youth,

⁴ And her father hears her vow and her pledge with which she has bound herself and he offers no objection, then all her vows shall stand and every pledge with which she has bound herself shall stand.

⁵ But if her father refuses to allow her [to carry out her vow] on the day that he hears about it, not any of her vows or of her pledges with which she has bound herself shall stand. And the Lord will forgive her because her father refused to let her [carry out her purpose].
