33 From Merari came the family of the Mahlites and the family of the Mushites; these were the families of Merari. 34 And those who were numbered, according to the number of all the males from a month old and above, were six thousand two hundred. 35 The leader of the fathers' house of the families of Merari was Zuriel the son of Abihail. These were to camp on the north side of the tabernacle. 36 And the appointed duty of the children of Merari included the boards of the tabernacle, its bars, its pillars, its sockets, its utensils, all the work relating to them, 37 and the pillars of the court all around, with their sockets, their pegs, and their 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.
