Numbers 30:6-8

6“If a woman marries while her vows or the rash commitment she herself made are binding,

7and her husband hears about it and says nothing to her when he finds out, her vows are binding, and the obligations she put herself under are binding.

8But if her husband prohibits her when he hears about it, he will cancel her vow that is binding or the rash commitment she herself made, and the Lord will release her.
