Exodus 6:22-26

And the sons of Uzziel: Mishael, Elzaphan, and Sithri.

Aaron married Elisheba, the daughter of Amminadab, the sister of Nahshon, and she bore him Nadab and Abihu, Eleazar and Ithamar.

And the sons of Korah: Assir, Elkanah, and Abiasaph; these are the families of the Korahites.

Now Aaron’s son Eleazar married one of the daughters of Putiel, and she bore him Phinehas. These are the heads of the fathers’ households of the Levites according to their families.

It was the same Aaron and Moses to whom the Lord said, “Bring out the sons of Israel from the land of Egypt according to their multitudes.”
