Of Gershon was the family of the Libnites, and the family of the Shimites,.... The first son of Levi:

these are the family of the Gershonites; that were now, numbered.

The Gershonites were divided into two families, containing 7500 males. They were to encamp under their chief Eliasaph, behind the tabernacle, i.e., on the western side (Numbers 3:23, Numbers 3:24), and were to take charge of the dwelling-place and the tent, the covering, the curtain at the entrance, the hangings round the court with the curtains at the door, and the cords of the tent, "in relation to all the service thereof" (Numbers 3:25.); that is to say, according to the more precise injunctions in Numbers 4:25-27, they were to carry the tapestry of the dwelling (the inner covering, Exodus 26:1.), and of the tent (i.e., the covering made of goats' hair, Exodus 26:7.), the covering thereof (i.e., the covering of rams' skins dyed red, and the covering of sea-cow skin upon the top of it, Exodus 27:16), the hangings of the court and the curtain at the entrance (Exodus 27:9, Exodus 27:16), which surrounded the altar (of burnt-offering) and the dwelling round about, and their cords, i.e., the cords of the tapestry, coverings, and curtains (Exodus 27:14), and all the instruments of their service, i.e., the things used in connection with their service (Exodus 27:19), and were to attend to everything that had to be done to them; in other words, to perform whatever was usually done with those portions of the sanctuary that are mentioned here, especially in setting up the tabernacle or taking it down. The suffix in מיתריו (Numbers 3:26) does not refer to the court mentioned immediately before; for, according to Numbers 3:37, the Merarites were to carry the cords of the hangings of the court, but to the "dwelling and tent," which stand farther off. In the same way the words, "for all the service thereof," refer to all those portions of the sanctuary that are mentioned, and mean "everything that had to be done or attended to in connection with these things."

Of Gershon was the family of the Libnites, and the family of the Shimites: these are the families of the Gershonites.

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.
