Numbers 3:30-32

The leader of the Kohathite clans was Elizaphan son of Uzziel. These four clans were responsible for the care of the Ark, the table, the lampstand, the altars, the various articles used in the sanctuary, the inner curtain, and all the equipment related to their use. Eleazar, son of Aaron the priest, was the chief administrator over all the Levites, with special responsibility for the oversight of the sanctuary.
