33 To Merari belonged the clan of the Mahlites and the clan of the Mushites: these are the clans of Merari. 34 Their listing according to the number of all the males from a month old and upward was 6,200. 35 And the chief of the fathers' house of the clans of Merari was Zuriel the son of Abihail. They were to camp on the north side of the tabernacle. 36 And the appointed guard duty of the sons of Merari involved the frames of the tabernacle, the bars, the pillars, the bases, and all their accessories; all the service connected with these; 37 also the pillars around the court, with their bases and pegs and cords.

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.
