'Duty' in the Bible

Then Judah said to Onan, "Have sexual relations with your brother's wife and fulfill the duty of a brother-in-law to her so that you may raise up a descendant for your brother."

If brothers live together and one of them dies without having a son, the dead man's wife must not remarry someone outside the family. Instead, her late husband's brother must go to her, marry her, and perform the duty of a brother-in-law.

But if the man does not want to marry his brother's widow, then she must go to the elders at the town gate and say, "My husband's brother refuses to preserve his brother's name in Israel; he is unwilling to perform the duty of a brother-in-law to me!"

He ordered them, "This is what you must do. One third of the unit that is on duty during the Sabbath will guard the royal palace.

The two units who are off duty on the Sabbath will guard the Lord's temple and protect the king.

The officers of the units of hundreds did just as Jehoiada the priest ordered. Each of them took his men, those who were on duty during the Sabbath as well as those who were off duty on the Sabbath, and reported to Jehoiada the priest.

This is what you must do. One third of you priests and Levites who are on duty during the Sabbath will guard the doors.

No one must enter the Lord's temple except the priests and Levites who are on duty. They may enter because they are ceremonially pure. All the others should carry out their assigned service to the Lord.

The Levites and all the men of Judah did just as Jehoiada the priest ordered. Each of them took his men, those who were on duty during the Sabbath as well as those who were off duty on the Sabbath. Jehoiada the priest did not release his divisions from their duties.

Having heard everything, I have reached this conclusion: Fear God and keep his commandments, because this is the whole duty of man.

"The Lord has made you priest in place of Jehoiada. He has put you in charge in the Lord's temple of controlling any lunatic who pretends to be a prophet. And it is your duty to put any such person in the stocks with an iron collar around his neck.

When the scouts survey the land and see a human bone, they will place a sign by it, until those assigned to burial duty have buried it in the valley of Hamon-Gog.

It will be the duty of the prince to provide the burnt offerings, the grain offering, and the drink offering at festivals, on the new moons and Sabbaths, at all the appointed feasts of the house of Israel; he will provide the sin offering, the grain offering, the burnt offering, and the peace offerings to make atonement for the house of Israel.

Now while Zechariah was serving as priest before God when his division was on duty,

So you too, when you have done everything you were commanded to do, should say, 'We are slaves undeserving of special praise; we have only done what was our duty.'"

But if a widow has children or grandchildren, they should first learn to fulfill their duty toward their own household and so repay their parents what is owed them. For this is what pleases God.

Give a shepherd's care to God's flock among you, exercising oversight not merely as a duty but willingly under God's direction, not for shameful profit but eagerly.
