Exodus 7:3-5

3But 1I will harden Pharaoh’s heart, so that I may 2multiply My signs and My wonders in the land of Egypt.

4When 3Pharaoh does not listen to you, I will lay My hand on Egypt and 4bring out My armies, My people the sons of Israel, from the land of Egypt by 5great judgments.

5Then 6the Egyptians shall know that I am the Lord, when I 7extend My hand over Egypt and bring out the sons of Israel from their midst.”
