Exodus 7:20-22

21st Century King James Version

²⁰ And Moses and Aaron did so, as the Lord commanded; and he lifted up the rod and smote 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 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.
