'Obligation' in the Bible

If a man makes a vow to the Lord or takes an oath of binding obligation on himself, he must not break his word, but must do whatever he has promised.

"If a young woman who is still living in her father's house makes a vow to the Lord or places herself under an obligation,

and her father hears of her vow or the obligation to which she has pledged herself, and her father remains silent about her, then all her vows will stand, and every obligation to which she has pledged herself will stand.

If she made the vow in her husband's house or put herself under obligation with an oath,

and her husband heard about it, but remained silent about her, and did not overrule her, then all her vows will stand, and every obligation which she pledged for herself will stand.

"Any vow or sworn obligation that would bring affliction to her, her husband can confirm or nullify.

and the land is subdued before the Lord, then afterward you may return and be free of your obligation to the Lord and to Israel. This land will then be your possession in the Lord's sight.
