English Standard Version
Chapter 7 20
Moses and Aaron did as the LORD commanded. In the sight of Pharaoh and in the sight of his servants he lifted up the staff and struck the water in the Nile, and all the water in the Nile turned into blood. 21
And the fish in the Nile died, and the Nile stank, so that the Egyptians could not drink water from the Nile. There was blood throughout all the land of Egypt. 22
But the magicians of Egypt did the same by their secret arts. So Pharaoh’s heart remained hardened, and he would not listen to them, as the LORD had said. 23
Pharaoh turned and went into his house, and he did not take even this to heart.
