21 The descendants of Gershon were composed of the clans descended from Libni and Shimei. 22 There were 7,500 males one month old or older among these Gershonite clans. 23 They were assigned the area to the west of the Tabernacle for their camp. 24 The leader of the Gershonite clans was Eliasaph son of Lael. 25 These two clans were responsible to care for the Tabernacle, including the sacred tent with its layers of coverings, the curtain at its entrance, 26 the curtains of the courtyard that surrounded the Tabernacle and altar, the curtain at the courtyard entrance, the ropes, and all the equipment related to their use.

Commentary on Numbers 3:14-39

(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.
