Numbers 30

Moses spoke with the leaders of the Israelite tribes. He told them these commands that God had given to him:

"If a man solemnly promises God that he will do something, he must do what he promised.

If a young woman who is still living with her parents solemnly promises to God to do something,

and if her father hears about what she promised, and if he does not say anything to her, she must do what she promised.

And if her father hears about her vow that she made before witnesses or the promise she had pledged, but even though he heard about them, he says nothing about what she has vowed or promised, then she must keep all her vows and all her promises, and they all will be in force and she must do what she promised to do.

If she marries a husband after she had made a vow or after she had made a careless promise by which she had obligated herself,

and her husband hears about the vow or the promise that she had made, but on the day that he hears about it he does nothing, in that case the vows she had made will stand in force, and her promises that she had made will still be an obligation that she must fulfill.

But if, on the day her husband hears about the vow she had given or the foolish promise she had made, he takes action to overrule her, then by overruling her he makes her pledges to be of no effect and he makes the promises that she had made to no longer be an obligation to her. Then God will set her free from the obligations that she had made when she had taken a vow or when she had made a foolish promise.

If a widow or a woman who has been divorced makes a promise, she must do what she promised.

If a woman who is married promises to do something,

and if her husband hears about it but does not object, she must do what she promised.

But if he hears about it and does not allow her to do that, she does not need to do what she promised, and God will forgive her for not doing it.

A woman's husband may require her to do what she has promised, or he may not allow her to do what she has promised.

If he does not object for several days after he hears about it, she must do what she promised.

But if he waits a long time after she has promised to do something and then he tells her that he will not permit her to do it, if she does not do what she promised, she will not be punished. Her husband is the one whom God will punish."

Those are the rules that God gave to Moses for husbands and wives, and for young women who are still living with their parents.
