Exodus 6:28-7:2

Aaron to Speak for Moses 28Now when the LORD spoke to Moses in Egypt,

29he said to him, “I am the LORD . Tell Pharaoh king of Egypt everything I tell you.” 30But Moses said to the LORD, “Since I speak with faltering lips, why would Pharaoh listen to me?”

1Then the LORD said to Moses, “See, I have made you like God to Pharaoh, and your brother Aaron will be your prophet. 2You are to say everything I command you, and your brother Aaron is to tell Pharaoh to let the Israelites go out of his country.
