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. ²¹ The fish that were in the river died, the river stank, and the Egyptians could not drink of the water of the river. Blood was everywhere throughout the land of Egypt.

²² Nevertheless, the magicians of Egypt did the same with their secret arts, and Pharaoh’s heart was hardened, and he did not listen to them, as the Lord had said.
