The sons of Kohath: Amram, Izhar, Hebron, and Uzziel, four. The sons of Amram: Aaron and Moses. Aaron was set apart to dedicate the most holy things, that he and his sons forever should make offerings before the LORD and minister to him and pronounce blessings in his name forever. But the sons of Moses the man of God were named among the tribe of Levi.
