'Obligations' in the Bible
They shall keep all the furnishings of the Tent of Meeting, and the obligations of the children of Israel, to do the service of the tabernacle.
He may minister to his brothers at the Tent of Meeting by keeping watch, but he is not to engage in service. This is how you are to act with respect to the obligations of the descendants of Levi."
They shall be joined with you and attend to the obligations of the tent of meeting, for all the service of the tent; but an outsider may not come near you.
So you shall attend to the obligations of the sanctuary and the obligations of the altar, so that there will no longer be wrath on the sons of Israel.
and her father hears her vow and the obligations that she had pledged herself to fulfill, yet her father keeps silent about it, then all her vows and every obligation she pledged herself to are to stand.
But if her father prohibits her on the day he hears about it, none of her vows and none of the obligations she put herself under are binding. The Lord will absolve her because her father has prohibited her.
and her husband hears about it and says nothing to her when he finds out, her vows are binding, and the obligations she put herself under are binding.
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.
