1 Then the Lord said to Moses, “See, I make you as God to Pharaoh, and your brother Aaron shall be your prophet. 2 You shall speak all that I command you, and your brother Aaron shall speak to Pharaoh that he let the sons of Israel go out of his land. 3 But I will harden Pharaoh’s heart that I may multiply My signs and My wonders in the land of Egypt. 4 When Pharaoh does not listen to you, then I will lay My hand on Egypt and bring out My hosts, My people the sons of Israel, from the land of Egypt by great judgments. 5 The Egyptians shall know that I am the Lord, when I stretch out My hand on Egypt and bring out the sons of Israel from their midst.”
6 So Moses and Aaron did it; as the Lord commanded them, thus they did. 7 Moses was eighty years old and Aaron eighty-three, when they spoke to Pharaoh.
