And he also rebelled against King Nebuchadnezzar, who had made him swear an oath by God; but he stiffened his neck and hardened his heart against turning to the Lord God of Israel.
And the Lord said to Moses, “When you go back to Egypt, see that you do all those wonders before Pharaoh which I have put in your hand. 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 spread out his hands to the Lord; then the thunder and the hail ceased, and the rain was not poured on the earth.
Why then do you harden your hearts as the Egyptians and Pharaoh hardened their hearts? When He did mighty things among them, did they not let the people go, that they might depart?
