Exodus 7:22 in the King James Version
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.
Context
21 The fish that were in the river died. The river became foul. The Egyptians couldn’t drink water from the river. The blood was throughout all the land of Egypt.
22 The magicians of Egypt did the same thing with their enchantments. So Pharaoh’s heart was hardened, and he didn’t listen to them, as the LORD had spoken.
23 Pharaoh turned and went into his house, and he didn’t even take this to heart.
