Exodus 7:3-4
Exodus 7:3-4 AMP
And I will make Pharaoh’s heart hard, and multiply My signs and My wonders (miracles) in the land of Egypt. But Pharaoh will not listen to you, and I shall lay My hand on Egypt and bring out My hosts [like a defensive army, tribe by tribe], My people the children of Israel, out of the land of Egypt by great acts of judgment (the plagues).
