Numbers 30:7-9

New Catholic Bible

⁷ and her husband hears about it, and he says nothing to her on the day that he hears about it, then her vows and the oaths with which she bound herself will be valid. ⁸ But if her husband forbids it on the day that he hears about it, then he makes void the vows she has made and the rash statements from her mouth by which she has bound herself. The Lord will release her.

⁹ “Any vow or obligation made by a widow or a divorced woman by which she bound herself will be binding.
