Numbers 3:21-26

Of Gershon were the families of the Libnites and of the Shimeites. These are the families of the Gershonites. The males who were numbered, every male from a month old and upward totaled 7,500. The families of the Gershonites were to camp behind the tabernacle on the west, and the leader of the fathers’ households of the Gershonites was Eliasaph the son of Lael. Now the responsibilities of the sons of Gershon in the Tent of Meeting involved the tabernacle and the tent, its covering, and the curtain for the doorway of the Tent of Meeting, and the hangings of the courtyard, the curtain for the doorway of the courtyard which is around the tabernacle and the altar, its tent ropes, and all the service concerning them.
