Numbers 30:10-15

“But suppose a woman is married and living in her husband’s home when she makes a vow or binds herself with a pledge. If her husband hears of it and does not object to it, her vow or pledge will stand. But if her husband refuses to accept it on the day he hears of it, her vow or pledge will be nullified, and the LORD will forgive her. So her husband may either confirm or nullify any vows or pledges she makes to deny herself. But if he does not object on the day he hears of it, then he is agreeing to all her vows and pledges. If he waits more than a day and then tries to nullify a vow or pledge, he will be punished for her guilt.”
