1 Chronicles 23:12-14, 18-23

The four sons of Kohath: Amram, Izhar, Hebron, and Uzziel. The sons of Amram: Aaron and Moses. Aaron was especially ordained to work in the Holy of Holies, to burn incense before GOD, to serve God and bless his Name always. This was a permanent appointment for Aaron and his sons. Moses and his sons were counted in the tribe of Levi.

Shelomith was the first son of Izhar. Hebron had four sons: Jeriah, Amariah, Jahaziel, and Jekameam. Uzziel had two sons: Micah and Isshiah. The sons of Merari: Mahli and Mushi. The sons of Mahli: Eleazar and Kish. Eleazar died without any sons, only daughters. Their cousins, the sons of Kish, married the daughters. Mushi had three sons: Mahli, Eder, and Jerimoth.
