'Harden' in the Bible

And Yahweh said to Moses, "When you go to return to Egypt, see all of the wonders that I have put in your hand, and do them before Pharaoh, and I myself will harden his heart, and he will not release the people.

And I myself will harden the heart of Pharaoh, and I will make my signs and my wonders numerous in the land of Egypt.

And I will harden the heart of Pharaoh, and he will chase after them, and I will be glorified through Pharaoh and through all his army, and [the] Egyptians will know that I [am] Yahweh." And they did so.

And as for me, look, I [am] about to harden the heart of [the] Egyptians [so that] they come after them, and I will display my glory through Pharaoh and through all of his army, through his chariots and through his charioteers.
