Numbers 3:30-32

And the chief of the house of the father of the families of the Kohathites shall be Elizaphan the son of Uzziel. And their charge shall be the ark, and the table, and the candlestick, and the altars, and the vessels of the sanctuary wherewith they minister, and the hanging, and all the service thereof. And Eleazar the son of Aaron the priest shall be chief over the chief of the Levites, and have the oversight of them that keep the charge of the sanctuary.
