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