'Harden' in the Bible

The Lord said to Moses, “When you return to Egypt, see that you perform before Pharaoh all the wonders (miracles) which I have put in your hand, but I will harden his heart and make him stubborn so that he will not let the people go.

I will harden (make stubborn, defiant) Pharaoh’s heart, so that he will pursue them; and I will be glorified and honored through Pharaoh and all his army, and the Egyptians shall know [without any doubt] and acknowledge that I am the Lord.” And they did so.

As for Me, hear this: I will harden the hearts of the Egyptians, and they will go in [the sea] after them; and I will be glorified and honored through Pharaoh and all his army, and his war-chariots and his horsemen.
