Numbers 30:8-12

8But if her husband refuses to accept her vow or impulsive pledge on the day he hears of it, he nullifies her commitments, and the Lord will forgive her.

9If, however, a woman is a widow or is divorced, she must fulfill all her vows and pledges.

10“But suppose a woman is married and living in her husband’s home when she makes a vow or binds herself with a pledge.

11If her husband hears of it and does not object to it, her vow or pledge will stand.

12But 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.
