יהוה said to Moses, “Pharaoh’s heart is stubborn. He refuses to let the people go. Go to Pharaoh in the morning. Behold, he is going out to the water. You shall stand by the river’s bank to meet him. You shall take the rod which was turned to a serpent in your hand. You shall tell him, ‘יהוה, the God of the Hebrews, has sent me to you, saying, “Let my people go, that they may serve me in the wilderness. Behold, until now you haven’t listened.” יהוה says, “In this you shall know that I am יהוה. Behold: I will strike with the rod that is in my hand on the waters which are in the river, and they shall be turned to blood. 18 The fish that are in the river will die and the river will become foul. The Egyptians will loathe to drink water from the river.” יהוה said to Moses, “Tell Aaron, ‘Take your rod, and stretch out your 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. There will be blood throughout all the land of Egypt, both in vessels of wood and in vessels of stone.’ ” Moses and Aaron did so, as יהוה commanded; and he lifted up the rod, and struck 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. The fish that were in the river died. The river became foul. The Egyptians couldn’t drink water from the river. The blood was throughout all the land of Egypt. The magicians of Egypt did the same thing with their enchantments. So Pharaoh’s heart was hardened, and he didn’t listen to them, as יהוה had spoken. Pharaoh turned and went into his house, and he didn’t even take this to heart. All the Egyptians dug around the river for water to drink; for they couldn’t drink the river water. Seven days were fulfilled, after יהוה had struck the river.
