And the LORD said unto Moses, Go in unto Pharaoh: for I have hardened his heart, and the heart of his servants, that I might show these my signs before him:
Get you unto Pharaoh in the morning; lo, he goes out unto the water; and you shall stand by the river's bank until he comes; and the rod which was turned to a serpent shall you take in your hand.
And Pharaoh sent, and, behold, there was not one of the cattle of the Israelites dead. And the heart of Pharaoh was hardened, and he did not let the people go.
Yea, they made their hearts as a flint stone, lest they should hear the law, and the words which the LORD of hosts has sent by his Spirit through the former prophets: therefore came a great wrath from the LORD of hosts.
But Sihon king of Heshbon would not let us pass by him: for the LORD your God hardened his spirit, and made his heart obstinate, that he might deliver him into your hand, as it is this day.

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?
