Gershon was ancestor to the clans of the Libnites and Shimeites, known as the Gershonite clans. All the males who were one month and older numbered 7,500. The Gershonite clans camped on the west, behind The Dwelling, led by Eliasaph son of Lael. At the Tent of Meeting the Gershonites were in charge of maintaining The Dwelling and its tent, its coverings, the screen at the entrance to the Tent of Meeting, the hangings of the Courtyard, the screen at the entrance to the Courtyard that surrounded The Dwelling and Altar, and the cords—in short, everything having to do with these things.
