Exod 6:28-7:7

Moses and Aaron Obey God's Commands 28On the day when the Lord spoke to Moses in the land of Egypt,29he said to him, “I am the Lord; tell Pharaoh king of Egypt all that I am speaking to you.”30But Moses said in the Lord's presence, “Since I am a poor speaker, why would Pharaoh listen to me?”Chapter 71The Lord said to Moses, “See, I have made you like God to Pharaoh, and your brother Aaron shall be your prophet.2You shall speak all that I command you, and your brother Aaron shall tell Pharaoh to let the Israelites go out of his land.3But I will harden Pharaoh's heart, and I will multiply my signs and wonders in the land of Egypt.4When Pharaoh does not listen to you, I will lay my hand upon Egypt and bring my people the Israelites, company by company, out of the land of Egypt by great acts of judgment.5The Egyptians shall know that I am the Lord, when I stretch out my hand against Egypt and bring the Israelites out from among them.”6Moses and Aaron did so; they did just as the Lord commanded them.7Moses was eighty years old and Aaron eighty-three when they spoke to Pharaoh.
