Exodus 7:19-25

GOD said to Moses, “Tell Aaron, ‘Take your staff and wave it over the waters of Egypt—over its rivers, its canals, its ponds, all its bodies of water—so that they turn to blood.’ There’ll be blood everywhere in Egypt—even in the pots and pans.” Moses and Aaron did exactly as GOD commanded them. Aaron raised his staff and hit the water in the Nile with Pharaoh and his servants watching. All the water in the Nile turned into blood. The fish in the Nile died; the Nile stank; and the Egyptians couldn’t drink the Nile water. The blood was everywhere in Egypt. But the magicians of Egypt did the same thing with their incantations. Still Pharaoh remained stubborn. He wouldn’t listen to them as GOD had said. He spun around and went home, never giving it a second thought. But all the Egyptians had to dig inland from the river for water because they couldn’t drink the Nile water. Seven days went by after GOD had struck the Nile.
