Exodus 7:18-21

18The fish in the Nile shall die, and the Nile will stink, and the Egyptians will agrow weary of drinking water from the Nile.”’” 19And the Lord said to Moses, “Say to Aaron, ‘Take your staff and bstretch out your hand over the waters of Egypt, over their rivers, their canals, and their ponds, and all their pools of water, so that they may become blood, and there shall be blood throughout all the land of Egypt, even in vessels of wood and in vessels of stone.’”

20Moses and Aaron did as the Lord commanded. In the sight of Pharaoh and in the sight of his servants he clifted up the staff and struck the water in the Nile, and all the dwater in the Nile turned into blood. 21And the fish in the Nile died, and the Nile stank, so that the Egyptians ecould not drink water from the Nile. There was blood throughout all the land of Egypt.
