And he also rebelled against king Nebuchadnezzar, who had made him swear by God: but he stiffened his neck, and hardened his heart against turning unto the LORD God of Israel.
And the LORD said unto Moses, When you go to return into Egypt, see that you do all those wonders before Pharaoh, whom I have put in your hand: but I will harden his heart, that he shall not let the people go.
And Moses went out of the city from Pharaoh, and stretched forth his hands unto the LORD: and the thunders and hail ceased, and the rain was not poured upon the earth.
Why then do you harden your hearts, as the Egyptians and Pharaoh hardened their hearts? when he had worked wonderfully among them, did they not let the people go, and they departed?
