Numbers 3:30-32

And the leader of the fathers’ house of the families of the Kohathites was Elizaphan the son of Uzziel. Their duty included the ark, the table, the lampstand, the altars, the utensils of the sanctuary with which they ministered, the screen, and all the work relating to them. And Eleazar the son of Aaron the priest was to be chief over the leaders of the Levites, with oversight of those who kept charge of the sanctuary.
