18And these are the names of the sons of Gershon by their families: Libni and Shimei. 19And the sons of Kohath by their families: Amram, and Izhar, Hebron, and Uzziel. 20And the sons of Merari by their families: Mahli and Mushi. These are the families of the Levites according to their fathers’ houses.

21Of Gershon was the family of the Libnites, and the family of the Shimeites: these are the families of the Gershonites. 22Those that were numbered of them, according to the number of all the males, from a month old and upward, even those that were numbered of them were seven thousand and five hundred. 23The families of the Gershonites shall encamp behind the tabernacle westward. 24And the prince of the fathers’ house of the Gershonites shall be Eliasaph the son of Lael. 25And the charge of the sons of Gershon in the tent of meeting shall be the tabernacle, and the Tent, the covering thereof, and the screen for the door of the tent of meeting, 26and the hangings of the court, and the screen 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.
