Exodus 6:26-29

26These are the same Aaron and Moses to whom the Lord said, “Bring out the children of Israel from the land of Egypt according to their armies.”

27These are the ones who spoke to Pharaoh king of Egypt, to bring out the children of Israel from Egypt. These are the same Moses and Aaron.

28And it came to pass, on the day the Lord spoke to Moses in the land of Egypt,

29that the Lord spoke to Moses, saying, “I am the Lord. Speak to Pharaoh king of Egypt all that I say to you.”
