Numbers 3:30-32

and the leader of the fathers’ households of the Kohathite families was Elizaphan the son of Uzziel. Now their duties 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 Eleazar the son of Aaron the priest was the chief of the leaders of Levi, and had the oversight of those who perform the duties of the sanctuary.
