Exodus 6:25-27

25Eleazar son of Aaron married one of the daughters of Putiel, and she bore him Phinehas. These were the heads of the Levite families, clan by clan. 26It was this Aaron and Moses to whom the LORD said, “Bring the Israelites out of Egypt by their divisions.”

27They were the ones who spoke to Pharaoh king of Egypt about bringing the Israelites out of Egypt—this same Moses and Aaron.
