And the sons of Kohath, by their families
Who was the second son of Levi: Amram, and Izehar, Hebron, and Uzziel;
so in ( Exodus 6:18 ) ; and from whom were named the family of the Amramites, to which Moses and Aaron belonged; and the families of the Izeharites, Hebronites, and Uzzielites, as they are called, ( Numbers 3:27 ) .
