Numbers 3:27-32

The Amramite clan, the Izharite clan, the Hebronite clan, and the Uzzielite clan came from Kohath; these were the Kohathites. Counting every male one month old or more, there were 8,600  responsible for the duties of  the sanctuary. The clans of the Kohathites camped on the south side of the tabernacle,  and the leader of the families of the Kohathite clans was Elizaphan son of Uzziel. Their duties involved the ark, the table, the lampstand, the altars, the sanctuary utensils that were used with these, and the screen  ,  — and all the work relating to them.  The chief of the Levite leaders was Eleazar  son of Aaron the priest; he had oversight of those responsible for the duties of the sanctuary.
