Numbers 30:9

9“Any vow or obligation taken by a widow or divorced woman will be binding on her.

9“But as for the vow of a widow or of a divorced woman, every binding obligation under which she has put herself, shall remain valid against her.

9“But the vow of a widow or of a divorced woman, everything by which she has bound herself, shall stand against her.

9“But the vow of a widow or of a divorced woman, everything by which she has bound herself, shall stand against her.

9 Every vow a widow or divorced woman pledges to fulfill is binding on her.

9“Suppose a widow makes a special promise. Or suppose she gives her word to do something. Then she must keep her promise. She must do what she agreed to do. The same rules apply to a woman who has been divorced.
