Numbers 3:24-30

24And the chief of the house of the father of the Gershonites shall be Eliasaph the son of Lael. 25And the charge of the sons of Gershon in the tabernacle of the congregation shall be the tabernacle, and the tent, the covering thereof, and the hanging for the door of the tabernacle of the congregation, 26And the hangings of the court, and the curtain for the door of the court, which is by the tabernacle, and by the altar round about, and the cords of it for all the service thereof.

27And of Kohath was the family of the Amramites, and the family of the Izeharites, 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 pitch on the side of the tabernacle southward. 30And the chief of the house of the father of the families of the Kohathites shall be Elizaphan the son of Uzziel.
