Numbers 3:27-31

27To Kohath belonged the clan of the Amramites and the clan of the Izharites and the clan of the Hebronites and the clan of the Uzzielites; these are the clans of the Kohathites.

28According to the number of all the males, from a month old and upward, there were 8,600, keeping guard over the sanctuary.

29The clans of the sons of Kohath were to camp on the south side of the tabernacle,

30with Elizaphan the son of Uzziel as chief of the fathers' house of the clans of the Kohathites.

31And their guard duty involved the ark, the table, the lampstand, the altars, the vessels of the sanctuary with which the priests minister, and the screen; all the service connected with these.
