Exodus 7:3-5

Revised Standard Version

³ But I will harden Pharaoh’s heart, and though I multiply my signs and wonders in the land of Egypt, ⁴ Pharaoh will not listen to you; then I will lay my hand upon Egypt and bring forth my hosts, my people the sons of Israel, out of the land of Egypt by great acts of judgment. ⁵ And the Egyptians shall know that I am the Lord, when I stretch forth my hand upon Egypt and bring out the people of Israel from among them.”
