Numbers 3:27-32

27And of Kohath was the family of the Amramites, and the family of the Izharites, and the family of the Hebronites, and the family of the Uzzielites: these are the families of the Kohathites. 28In the number of all the males, from a month old and upward, were eight thousand and six hundred, keeping the charge of the sanctuary. 29The families of the sons of Kohath shall encamp on the side of the tabernacle southward. 30And the head of the house of the father of the families of the Kohathites shall be Elizaphan the son of Uzziel. 31And their charge shall be the ark, and the table, and the lampstand, and the altars, and the vessels of the sanctuary by which they minister, and the hanging, and all the service of it. 32And Eleazar the son of Aaron the priest shall be chief over the leaders of the Levites, and have the oversight of them that keep the charge of the sanctuary.
