'Duties' in the Bible

They are to take care of his needs and the needs of the whole congregation at the Tent of Meeting by performing duties at the tent.

They are to take charge of the utensils at the Tent of Meeting and meet the needs of the Israelis by performing duties on behalf of the tent.

The duties of the descendants of Gershon at the Tent of Meeting pertained to the tent, the tent covering, the curtain to the entrance to the Tent of Meeting,

Their duties pertained to the ark, the table, the lamp stand, the altars, the utensils of the sanctuary with which they ministered, and all the curtains in use.

The duties of the caretakers from the descendants of Merari included the boards of the tent, its bars, crossbars, sockets, all its utensils for their services,

In front of the tent and east of the Tent of Meeting, Moses, Aaron, and Aaron's sons encamped facing the east. They were tasked to perform the duties of the sanctuary and care for the needs of the Israelis. Any unauthorized person who approached was to be executed.

"When Aaron and his sons have finished covering the sanctuary and all the utensils of the sanctuary, and the camp is about to travel, then the descendants of Kohath are to come and carry them, but they are not to touch the most sacred objects, so they won't die. These are the duties of the descendants of Kohath at the Tent of Meeting."

"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."

This is the work of the tribes of Gershon at the Tent of Meeting their duties under the supervision of Ithamar, the son of Aaron the priest.

Now you and your sons with you are to maintain your priestly duties and all matters that concern the altar and what is housed within the veil. You are to perform these services. I'm giving you the priesthood as a gift of service, but any unauthorized person who approaches is to be put to death."
