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.And under the custody and charge of the sons of Merari shall be the boards of the tabernacle,.... Both of the holy and the most holy place, which were the walls of the tabernacle, and which were covered with curtains; these when taken down for journeying were committed to the care of the Merarites; and because these, with what, follow, were a heavy carriage, they were allowed wagons to carry them; and who on this account had more wagons given them than to the Gershonites, for the Kohathites had none, Numbers 7:6,

and the bars thereof; which kept the boards tight and close, see Exodus 26:26,

and the pillars thereof; the pillars on which the vail was hung, that divided between the holy and most holy place, and, on which the hanging was put for the door of the vail, Exodus 26:32,

and the sockets thereof; in which both the boards and pillars were put, Exodus 26:19.
