Exodus 7:21-23

21st Century King James Version

²¹ And the fish that were in the river died; and the river stank, and the Egyptians could not drink of the water of the river; and there was blood throughout all the land of Egypt.

²² And the magicians of Egypt did so with their enchantments; and Pharaoh’s heart was hardened, neither did he hearken unto them, as the Lord had said.

²³ And Pharaoh turned and went into his house, neither did he set his heart to this also.
