1 Chronicles 23:12-13, 18-20

The sons of Kohath: Amram, Izhar, Hebron, and Uzziel, four. The sons of Amram: Aaron and Moses; and Aaron was separated, that he should sanctify the most holy things, he and his sons, for ever, to burn incense before Jehovah, to minister unto him, and to bless in his name, for ever.

The sons of Izhar: Shelomith the chief. The sons of Hebron: Jeriah the chief, Amariah the second, Jahaziel the third, and Jekameam the fourth. The sons of Uzziel: Micah the chief, and Isshiah the second.
