Exodus 7:21-23

New American Standard Bible

²¹ Then the fish that were in the Nile died, and the Nile stank, so that the Egyptians could not drink water from the Nile. And the blood was through all the land of Egypt. ^22 (A)But the soothsayer priests of Egypt did the same with their secret arts; and Pharaoh’s heart was ^[a]hardened, and he did not listen to them, just as the Lord had said. ²³ Then Pharaoh turned and went into his house ^[b]with no concern even for this.
