Exodus 9:35

And the heart of Pharaoh was hardened, neither would he let the children of Israel go; as the LORD had spoken by Moses.

The heart of Pharaoh was hardened, and he didn't let the children of Israel go, just as Yahweh had spoken through Moses.

And the heart of Pharaoh was hardened, and he did not let the children of Israel go, as Jehovah had spoken by Moses.

and the heart of Pharaoh is strong, and he hath not sent the sons of Israel away, as Jehovah hath spoken by the hand of Moses.

So Pharaoh’s heart was hardened, and he would not let the Israelites go, just as the LORD had said through Moses.
