Numbers 30:7-9

New Revised Standard Version, Anglicised Catholic Edition

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. ⁸ But if, at the time that her husband hears of it, he expresses disapproval to her, then he shall nullify the vow by which she was obligated, or the thoughtless utterance of her lips, by which she bound herself; and the Lord will forgive her. ⁹ (But every vow of a widow or of a divorced woman, by which she has bound herself, shall be binding upon her.)
