Exodus 6:26-30

This is the Aaron and Moses whom GOD ordered: “Bring the Israelites out of the land of Egypt clan by clan.” These are the men, Moses and Aaron, who told Pharaoh king of Egypt to release the Israelites from Egypt. And that’s how things stood when GOD next spoke to Moses in Egypt. God addressed Moses, saying, “I am GOD. Tell Pharaoh king of Egypt everything I say to you.” And Moses answered, “Look at me. I stutter. Why would Pharaoh listen to me?”
