Verse 30. - Elizaphan the son of Uzziel - of the youngest branch. This may have aroused the jealousy of Korah, who represented an elder branch.

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 the chief of the house of the father of the families of the Kohathites shall be Elizaphan the son of Uzziel. The same man, who, with his brother Mishael, carried Nadab and Abihu out of the camp, and buried them, Leviticus 10:4; he descended from the last and youngest of the families of the Kohathites; and some think this was one reason at least of Korah's dissatisfaction, and of his entering into a conspiracy against Moses and Aaron, because one of a younger family of his house was preferred to this dignity before him.
