"When a woman who is living with her husband makes a vow or takes a pledge under oath
and her husband hears about it but says nothing and doesn't say she can't do it, then all her vows and pledges are valid.
But if her husband cancels them when he hears about them, then none of the vows and pledges that she made are binding. Her husband has canceled them and God will release her.
Any vow and pledge that she makes that may be to her detriment can be either affirmed or annulled by her husband.
But if her husband is silent and doesn't speak up day after day, he confirms her vows and pledges - she has to make good on them. By saying nothing to her when he hears of them, he binds her to them.
If, however, he cancels them sometime after he hears of them, he takes her guilt on himself."
These are the rules that God gave Moses regarding conduct between a man and his wife and between a father and his young daughter who is still living at home.
