Numbers 30:4-9

4and her father hears of the vow or pledge and does not object to it, then all her vows and pledges will stand.

5But if her father refuses to let her fulfill the vow or pledge on the day he hears of it, then all her vows and pledges will become invalid. The Lord will forgive her because her father would not let her fulfill them.

6“Now suppose a young woman makes a vow or binds herself with an impulsive pledge and later marries.

7If her husband learns of her vow or pledge and does not object on the day he hears of it, her vows and pledges will stand.

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.
