And Eleazar the son of Aaron the priest shall be head over the leaders of the Levites, and have the oversight of them that keep the charge of the sanctuary.
And their charge shall be the ark, and the table, and the lampstand, and the altars, and the vessels of the sanctuary with which they minister, and the hanging, and all the service thereof.
And to the office of Eleazar the son of Aaron the priest pertains the oil for the light, and the sweet incense, and the daily grain offering, and the anointing oil, and the oversight of all the tabernacle, and of all that is therein, in the sanctuary, and in the utensils thereof.
At the appointment of Aaron and his sons shall be all the service of the sons of the Gershonites, in all their burdens, and in all their service: and you shall appoint unto them the task of all their burdens.
But shall minister with their brethren in the tabernacle of meeting, to keep the charge, and shall do no service. Thus shall you do unto the Levites regarding their duties.
