1 Chronicles 23:12-14
12-14The 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.
15-17The sons of Moses: Gershom and Eliezer. Shubael was the first son of Gershom. Rehabiah was the first and only son of Eliezer; but though Eliezer had no other sons, Rehabiah had many sons.
