Numbers 30:5-7

New American Standard Bible

⁵ But if her father expresses disapproval to her on the day he hears of it, none of her vows or her obligations under which she has put herself shall remain valid; and the Lord will ^[a]forgive her because her father has expressed disapproval to her.

⁶ “However, if she happens to ^[b]marry while ^[c]under her vows or the impulsive statement of her lips by which she has obligated herself, ⁷ and her husband hears of it and says nothing to her on the day he hears it, then her vows shall remain valid and her binding obligations under which she has put herself shall remain valid.
