Numbers 30:5-7

New Revised Standard Version, Anglicised

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.

⁶ If she marries, while obligated by her vows or any thoughtless utterance of her lips by which she has bound herself, ⁷ and her husband hears of it and says nothing to her at the time that he hears, then her vows shall stand, and her pledges by which she has bound herself shall stand.
