Pharaoh's heart was hardened, and he didn't listen to them; as Yahweh had spoken.

The magicians of Egypt did the same thing with their enchantments; and Pharaoh's heart was hardened, and he didn't listen to them; as Yahweh had spoken.

Then the magicians said to Pharaoh, "This is the finger of God:" and Pharaoh's heart was hardened, and he didn't listen to them; as Yahweh had spoken.
