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 of Kohath was the family of the Amramites,.... So called from Amram, the first son of Kohath, and father of Aaron and Moses; so that Moses and Aaron, and their children, are included in this family:

and the family of Izeharites; of which family was Korah, Numbers 16:1,

and the family of the Hebronites, and the family of the Uzzielites; which four families had their names from Kohath's four sons, Numbers 3:19,

these are the families of the Kohathites; which were as many as both the other sons of Levi.
