Exodus 7:4-6

Revised Standard Version

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.” ⁶ And Moses and Aaron did so; they did as the Lord commanded them.
