“When Pharaoh shall speak to you, saying, ‘Show a miracle,’ then you shall say to Aaron, ‘Take your rod, and throw it before Pharaoh,’ and it shall become a serpent.”
So Moses stretched forth his rod over the land of Egypt; then the Lord brought an east wind upon the land all that day and all that night. And when it was morning, the east wind brought the locusts.
Moses stretched forth his rod toward the heavens, and the Lord sent thunder and hail, and fire ran along upon the ground. So the Lord rained hail upon the land of Egypt.
Speak, and say, Thus says the Lord God: Behold, I am against you, Pharaoh king of Egypt, the great dragon that lies in the midst of his rivers, which has said, “My Nile is my own, and I myself have made it.”
