Exodus 7:4-6

American Standard Version

⁴ But Pharaoh will not hearken unto you, and I will lay my hand upon Egypt, and bring forth my hosts, my people the children of Israel, out of the land of Egypt by great judgments. ⁵ And the Egyptians shall know that I am Jehovah, when I stretch forth my hand upon Egypt, and bring out the children of Israel from among them. ⁶ And Moses and Aaron did so; as Jehovah commanded them, so did they.
