24The leader of the families of the Gershonites was Eliasaph son of Lael.

25At the tent of meeting the Gershonites were responsible for the care of the tabernacle and tent, its coverings, the curtain at the entrance to the tent of meeting,

26the curtains of the courtyard, the curtain at the entrance to the courtyard surrounding the tabernacle and altar, and the ropes—and everything related to their use.

27To Kohath belonged the clans of the Amramites, Izharites, Hebronites and Uzzielites; these were the Kohathite clans.

28The number of all the males a month old or more was 8,600. The Kohathites were responsible for the care of the sanctuary.

29The Kohathite clans were to camp on the south side of the tabernacle.
