Numbers 30:3-5

New Revised Standard Version, Anglicised

³ When a woman makes a vow to the Lord, or binds herself by a pledge, while within her father’s house, in her youth, ⁴ and her father hears of her vow or her pledge by which she has bound herself, and says nothing to her; then all her vows shall stand, and any pledge by which she has bound herself shall stand. ⁵ But if her father expresses disapproval to her at the time that he hears of it, no vow of hers, and no pledge by which she has bound herself, shall stand; and the Lord will forgive her, because her father had expressed to her his disapproval.
