Exodus 6:29--7:4

6:29 he said to him, “I am the Lord. Tell Pharaoh king of Egypt all that I am telling you.” 6:30 But Moses said before the Lord, “Since I speak with difficulty, why should Pharaoh listen to me?”

7:1 So the Lord said to Moses, “See, I have made you like God to Pharaoh, and your brother Aaron will be your prophet. 7:2 You are to speak everything I command you, and your brother Aaron is to tell Pharaoh that he must release the Israelites from his land. 7:3 But I will harden Pharaoh’s heart, and although I will multiply my signs and my wonders in the land of Egypt, 7:4 Pharaoh will not listen to you. I will reach into Egypt and bring out my regiments, my people the Israelites, from the land of Egypt with great acts of judgment.
