Eleazar the son of Aaron the priest shall be prince of the princes of the Levites, with the oversight of those who keep the requirements of the sanctuary.
Their duty shall be the ark, the table, the lamp stand, the altars, the vessels of the sanctuary with which they minister, the screen, and all its service.
“The duty of Eleazar the son of Aaron the priest shall be the oil for the light, the sweet incense, the continual meal offering, and the anointing oil, the requirements of all the tabernacle, and of all that is in it, the sanctuary, and its furnishings.”
At the commandment of Aaron and his sons shall be all the service of the sons of the Gershonites, in all their burden and in all their service; and you shall appoint their duty to them in all their responsibilities.
but shall assist their brothers in the Tent of Meeting, to perform the duty, and shall perform no service. This is how you shall have the Levites do their duties.”
