He also rebelled against King Nebuchadnezzar, who had made him swear by God; he stiffened his neck and hardened his heart against turning to the Lord, the God of Israel.
And the Lord said to Moses, “When you go back to Egypt, see that you do before Pharaoh all the miracles which I have put in your power; but I will harden his heart, so that he will not let the people go.
So Moses went out of the city from Pharaoh, and stretched out his hands to the Lord; and the thunder and the hail ceased, and the rain no longer poured upon the earth.
Why should you harden your hearts as the Egyptians and Pharaoh hardened their hearts? After he had made sport of them, did not they let the people go, and they departed?
