Numbers 30:1-8

Moses spoke to the heads of the tribes of the People of Israel: “This is what GOD commands: When a man makes a vow to GOD or binds himself by an oath to do something, he must not break his word; he must do exactly what he has said. “When a woman makes a vow to GOD and binds herself by a pledge as a young girl still living in her father’s house, and her father hears of her vow or pledge but says nothing to her, then she has to make good on all her vows and pledges. But if her father holds her back when he hears of what she has done, none of her vows and pledges are valid. GOD will release her since her father held her back. “If she marries after she makes a vow or has made some rash promise or pledge, and her husband hears of it but says nothing to her, then she has to make good on whatever she vowed or pledged. But if her husband intervenes when he hears of it, he cancels the vow or rash promise that binds her. And GOD will release her.
