33 Merari was ancestor to the clans of the Mahlites and the Mushites, known as the Merarite clans. 34 The males who were one month and older numbered 6,200. 35 They were led by Zuriel son of Abihail and camped on the north side of The Dwelling. 36 The Merarites were in charge of the frames of The Dwelling, its crossbars, posts, bases, and all its equipment - everything having to do with these things, 37 as well as the posts of the surrounding Courtyard with their bases, tent 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.
