Exodus 6:23-30 GNT

23 Aaron married Elisheba, the daughter of Amminadab and sister of Nahshon; she bore him Nadab, Abihu, Eleazar, and Ithamar.
24 Korah had three sons: Assir, Elkanah, and Abiasaph; they were the ancestors of the divisions of the clan of Korah.
25 Eleazar, Aaron's son, married one of Putiel's daughters, who bore him Phinehas. These were the heads of the families and the clans of the tribe of Levi.
26 Aaron and Moses were the ones to whom the Lord said, "Lead the tribes of Israel out of Egypt."
27 They were the men who told the king of Egypt to free the Israelites.
28 When the Lord spoke to Moses in the land of Egypt,
29 he said, "I am the Lord. Tell the king of Egypt everything I tell you."
30 But Moses answered, "You know that I am such a poor speaker; why should the king listen to me?"
