33 The descendants of Merari were composed of the clans descended from Mahli and Mushi. 34 There were 6,200 males one month old or older among these Merarite clans. 35 They were assigned the area north of the Tabernacle for their camp. The leader of the Merarite clans was Zuriel son of Abihail. 36 These two clans were responsible for the care of the frames supporting the Tabernacle, the crossbars, the pillars, the bases, and all the equipment related to their use. 37 They were also responsible for the posts of the courtyard and all their bases, pegs, and ropes.

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.
