1 Chronicles 23:12-14

The sons of Kohath were four: Amram, Izhar, Hebron and Uzziel. The sons of Amram were Aaron and Moses. And Aaron was set apart to sanctify him as most holy, he and his sons forever, to burn incense before the LORD, to minister to Him and to bless in His name forever. But as for Moses the man of God, his sons were named among the tribe of Levi.
