Exodus

Moses and Aaron Sent to Pharaoh

Chapter 6
28 And it was on the day when the LORD spoke to Moses in the land of Egypt. 29 And the LORD spoke to Moses, saying, "I am the LORD. Speak to Pharaoh king of Egypt all that I have spoken to you." 30 Moses said before the LORD, "See, I am uncircumcised of lips, and how will Pharaoh listen to me?"
Chapter 7
1 The LORD said to Moses, "See, I have made you God to Pharaoh, and Aaron your brother will be your prophet." 2 You will speak all that I command you, and Aaron your brother will speak to Pharaoh, and he will send the sons of Israel out from his land. 3 And I will harden Pharaoh's heart, and I will multiply my signs and my wonders in the land of Egypt. 4 Pharaoh will not listen to you, and I will lay my hand on Egypt. I will bring out my hosts, my people the sons of Israel, from the land of Egypt with great judgments. 5 Egypt will know that I am the LORD when I stretch out my hand upon Egypt and bring out the sons of Israel from their midst. 6 Moses and Aaron did as the LORD commanded them; they did so. 7 Moses was eighty years old and Aaron was eighty-three years old when they spoke to Pharaoh.
