Numbers 30:13-15
30:13 “Any vow or sworn obligation that would bring affliction to her, her husband can confirm or nullify.
30:14 But if her husband remains completely silent about her from day to day, he thus confirms all her vows or all her obligations which she is under; he confirms them because he remained silent about when he heard them.
30:15 But if he should nullify them after he has heard them, then he will bear her iniquity.”
