19. The Lord also said to Moses: "Say to Aaron: 'Take your staff; and extend your hand over the waters of Egypt, and over their rivers and streams and marshes and all the pools of waters, so that they may be turned into blood. And let there be blood throughout all the land of Egypt, as much in vessels of wood as in those of stone.' "
20. And Moses and Aaron did just as the Lord had instructed. And lifting up the staff, he struck the water of the river in the sight of Pharaoh and his servants. And it was turned into blood.
21. And the fishes that were in the river died, and the river was polluted, and the Egyptians were not able to drink the water of the river, and there was blood throughout the entire land of Egypt.
22. And the sorcerers of the Egyptians, with their incantations, did similarly. And the heart of Pharaoh was hardened, he did not listen to them, just as the Lord had instructed.
23. And he turned himself away, and he entered his house, neither did he apply his heart to this turn of events.
24. Then all the Egyptians dug along the borders of the river for water to drink. For they were not able to drink from the water of the river.
25. And seven days were completed, after the Lord struck the river.
