Numbers 30:3-5

Amplified Bible

³ “Also if a woman makes a vow to the Lord and binds herself by a pledge [of abstinence], while living in her father’s house in her youth, ⁴ and her father hears her vow and her pledge by which she has bound herself, and he offers no objection, then all her vows shall stand and every pledge by which she has bound herself shall stand. ⁵ But if her father disapproves of her [making her vow] on the day that he hears about it, none of her vows or her pledges by which she has bound herself shall stand; and the Lord will forgive her because her father has disapproved of her [making the vow].
