Exodus 7:2-4

Revised Standard Version

² You shall speak all that I command you; and Aaron your brother shall tell Pharaoh to let the people of Israel go out of his land. 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.
