21 From Gershon came the family of the Libnites and the family of the Shimites; these were the families of the Gershonites. 22 Those who were numbered, according to the number of all the males from a month old and above--of those who were numbered there were seven thousand five hundred. 23 The families of the Gershonites were to camp behind the tabernacle westward. 24 And the leader of the fathers' house of the Gershonites was Eliasaph the son of Lael. 25 The duties of the children of Gershon in the tabernacle of meeting included the tabernacle, the tent with its covering, the screen for the door of the tabernacle of meeting, 26 the screen for the door of the court, the hangings of the court which are around the tabernacle and the altar, and their cords, according to all the work relating to them.

(Read Numbers 3:14-39)
The Levites were in three classes, according to the sons of Levi; Gershon, Kohath, and Merari; and these were subdivided into families. The posterity of Moses were not at all honoured or privileged, but stood upon the level with other Levites; thus it was plain, that Moses did not seek the advancement of his own family, or to secure any honours to it. The tribe of Levi was by much the least of all the tribes. God's chosen are but a little flock in comparison with the world.
