28 Now when the Lord spoke to Moses in Egypt, 29 he said to him, “I am the Lord. Tell Pharaoh king of Egypt everything I tell you.”
30 But Moses said to the Lord, “Since I speak with faltering lips, why would Pharaoh listen to me?”
7:1 Then the Lord said to Moses, “See, I have made you like God to Pharaoh, and your brother Aaron will be your prophet. 2 You are to say everything I command you, and your brother Aaron is to tell Pharaoh to let the Israelites go out of his country. 3 But I will harden Pharaoh’s heart, and though I multiply my signs and wonders in Egypt, 4 he will not listen to you. Then I will lay my hand on Egypt and with mighty acts of judgment I will bring out my divisions, my people the Israelites. 5 And the Egyptians will know that I am the Lord when I stretch out my hand against Egypt and bring the Israelites out of it.”
6 Moses and Aaron did just as the Lord commanded them. 7 Moses was eighty years old and Aaron eighty-three when they spoke to Pharaoh.
