Exodus 9:12

And the LORD hardened the heart of Pharaoh, and he hearkened not unto them; as the LORD had spoken unto Moses.

Yahweh hardened the heart of Pharaoh, and he didn't listen to them, as Yahweh had spoken to Moses.

And Jehovah hardened the heart of Pharaoh, and he hearkened not unto them, as Jehovah had spoken unto Moses.

And Jehovah strengtheneth the heart of Pharaoh, and he hath not hearkened unto them, as Jehovah hath spoken unto Moses.

But the LORD hardened Pharaoh’s heart, and he would not listen to them, just as the LORD had said to Moses.
