'Obligations' in the Bible

But if her father overrules her when he hears about it, then none of her vows or her obligations which she has pledged for herself will stand. And the Lord will release her from it, because her father overruled her.

and her husband hears about it, but remains silent about her when he hears about it, then her vows will stand and her obligations which she has pledged for herself will stand.

But if her husband clearly nullifies them when he hears them, then whatever she says by way of vows or obligations will not stand. Her husband has made them void, and the Lord will release her from them.

But if her husband remains completely silent about her from day to day, he thus confirms all her vows or all her obligations which she is under; he confirms them because he remained silent about when he heard them.

The men of Israel said, "Have you seen this man who is coming up? He does so to defy Israel. But the king will make the man who can strike him down very wealthy! He will give him his daughter in marriage, and he will make his father's house exempt from tax obligations in Israel."
