Exodus 7:1-4

1Then the Lord said to Moses, “1See, I have made you as God to Pharaoh, and your brother Aaron shall be your prophet.

2As for you, you shall speak all that I command you, and your brother 2Aaron shall speak to Pharaoh that he let the sons of Israel go out of his land.

3But 3I will harden Pharaoh’s heart, so that I may 4multiply My signs and My wonders in the land of Egypt.

4When 5Pharaoh does not listen to you, I will lay My hand on Egypt and 6bring out My armies, My people the sons of Israel, from the land of Egypt by 7great judgments.
