Numbers 30:10-15

“If a woman in her husband’s house has made a vow or put herself under an obligation with an oath, and her husband hears about it, says nothing to her, and does not prohibit her, all her vows are binding, and every obligation she put herself under is binding. But if her husband cancels them on the day he hears about it, nothing that came from her lips, whether her vows or her obligation, is binding. Her husband has canceled them, and the LORD will absolve her. Her husband may confirm or cancel any vow or any sworn obligation to deny herself. If her husband says nothing at all to her from day to day, he confirms all her vows and obligations, which are binding. He has confirmed them because he said nothing to her when he heard about them. But if he cancels them after he hears about them, he will be responsible for her commitment.”
