1 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. Aaron was set apart, he and his descendants forever, to consecrate the most holy things, to offer sacrifices before the LORD, to minister before him and to pronounce blessings in his name forever.

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