I Chronicles 23:12-13, 18-20

The sons of Kohath: Amram, Izhar, Hebron, and Uzziel—four in all. The sons of Amram: Aaron and Moses; and Aaron was set apart, he and his sons forever, that he should sanctify the most holy things, to burn incense before the LORD, to minister to Him, and to give the blessing in His name forever.

Of the sons of Izhar, Shelomith was the first. Of the sons of Hebron, Jeriah was the first, Amariah the second, Jahaziel the third, and Jekameam the fourth. Of the sons of Uzziel, Michah was the first and Jesshiah the second.
