'Obligation' in the Bible
The bread is to be set out before the Lord every Sabbath day as a perpetual covenant obligation on the part of the Israelites.
When a man makes a vow to the Lord or swears an oath to put himself under an obligation, he must not break his word; he must do whatever he has promised.
“When a woman in her father’s house during her youth makes a vow to the Lord or puts herself under an obligation,
and her father hears about her vow or the obligation she put herself under, and he says nothing to her, all her vows and every obligation she put herself under are binding.
“If a woman in her husband’s house has made a vow or put herself under an obligation with an oath,
and her husband hears about it, says nothing to her, and does not prohibit her, all her vows are binding, and every obligation she put herself under is binding.
But if her husband cancels them on the day he hears about it, nothing that came from her lips, whether her vows or her obligation, is binding. Her husband has canceled them, and the Lord will absolve her.
Her husband may confirm or cancel any vow or any sworn obligation to deny herself.
and the land is subdued before the Lord—afterward you may return and be free from obligation to the Lord and to Israel. And this land will belong to you as a possession before the Lord.
and keep your obligation to the Lord your God to walk in His ways and to keep His statutes, commands, ordinances, and decrees. This is written in the law of Moses, so that you will have success in everything you do and wherever you turn,
Now we who are strong have an obligation to bear the weaknesses of those without strength, and not to please ourselves.
For if I preach the gospel, I have no reason to boast, because an obligation is placed on me. And woe to me if I do not preach the gospel!
