'Duty' in the Bible

The duty of the sons of Gershon in the Tent of Meeting shall be the tabernacle, and the tent, its covering, and the screen for the door of the Tent of Meeting,

Their duty shall be the ark, the table, the lamp stand, the altars, the vessels of the sanctuary with which they minister, and the screen, and all its service.

The appointed duty of the sons of Merari shall be the tabernacle's boards, its bars, its pillars, its sockets, all its instruments, all its service,

Those who encamp before the tabernacle eastward, in front of the Tent of Meeting toward the sunrise, shall be Moses, and Aaron and his sons, keeping the requirements of the sanctuary for the duty of the children of Israel. The stranger who comes near shall be put to death.

"Now the duty of Eleazar, the son of Aaron the priest is to maintain the oil for the light, the spiced incense, the daily offerings, and the oil for anointing, to carry out all the duties of the tent and the sanctuary, and to maintain its utensils."

Do this for them so that they may live and not die when they come near the most holy objects: Aaron and his sons are to go in and assign each man his task and transportation duty.

All the service of the sons of the Gershonites, in all their loads and in all their work, shall be performed at the command of Aaron and his sons; and you shall assign to them as a duty all their loads.

This is the service of the families of the sons of the Gershonites in the Tent of Meeting: and their duty shall be under the hand of Ithamar the son of Aaron the priest.

Now this is the duty of their loads, for all their service in the tent of meeting: the boards of the tabernacle and its bars and its pillars and its sockets,

and the pillars of the court around it, and their sockets, and their pins, and their cords, with all their instruments, and with all their service: and by name you shall appoint the instruments of the duty of their burden.

At the Lord’s command they were registered under the direction of Moses, each one according to his work and transportation duty, and his assignment was as the Lord commanded Moses.

but shall minister with their brothers in the Tent of Meeting, to perform the duty, and shall do no service. You shall do thus to the Levites concerning their duties."

They shall keep your commands, and the duty of all the Tent: only they shall not come near to the vessels of the sanctuary and to the altar, that they not die, neither they, nor you.

"You shall perform the duty of the sanctuary, and the duty of the altar; that there be wrath no more on the children of Israel.

Of the children of Israel's half, you shall take one drawn out of every fifty, of the persons, of the cattle, of the donkeys, and of the flocks, [even] of all the livestock, and give them to the Levites, who perform the duty of the tabernacle of Yahweh."

even of the children of Israel's half, Moses took one drawn out of every fifty, both of man and of animal, and gave them to the Levites, who performed the duty of the tabernacle of Yahweh; as Yahweh commanded Moses.
