and Eleazar the son of Aaron the priest was the chief of the leaders of Levi and had the oversight of those who keep the responsibility of the sanctuary.
Now their responsibility involved the ark, the table, the lampstand, the altars, and the utensils of the sanctuary with which they minister, and the screen, and all the service concerning them;
“And the assignment of Eleazar the son of Aaron the priest is the oil for the light and the fragrant incense and the continual grain offering and the anointing oil—the assignment of all the tabernacle and of all that is in it, with the sanctuary and its furnishings.”
All the service of the sons of the Gershonites, in all their loads and in all their service, shall be performed at the command of Aaron and his sons; and you shall assign to them as a responsibility all their loads.
They may, however, minister to their brothers in the tent of meeting in order to keep up their responsibility, but they themselves shall perform no service. Thus you shall deal with the Levites concerning their responsibilities.”
