Exodus

¹⁷Thus saith the Lord, In this thou shalt know that I am the Lord: behold, I will smite with the rod that is in mine hand upon the waters which are in the river, and they shall be turned to blood. ¹⁸And the fish that is in the river shall die, and the river shall stink; and the Egyptians shall loathe to drink water from the river. ¹⁹And the Lord said unto Moses, Say unto Aaron, Take thy rod, and stretch out thine hand over the waters of Egypt, over their rivers, over their streams, and over their pools, and over all their ponds of water, that they may become blood; and there shall be blood throughout all the land of Egypt, both in vessels of wood and in vessels of stone. ²⁰And Moses and Aaron did so, as the Lord commanded; and he lifted up the rod, and smote the waters that were in the river, in the sight of Pharaoh, and in the sight of his servants; and all the waters that were in the river were turned to blood. ²¹And the fish that was in the river died; and the river stank, and the Egyptians could not drink water from the river; and the blood was throughout all the land of Egypt. ²²And the magicians of Egypt did in like manner with their enchantments: and Pharaoh's heart was hardened, and he hearkened not unto them; as the Lord had spoken. ²³And Pharaoh turned and went into his house, neither did he lay even this to heart.
