And the LORD said to 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:
Go unto Pharaoh in the morning; lo, he goes out to the water; and you shall stand by the river’s edge for his coming; and the rod which was turned into 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 hard as an adamant stone, so that they would not hear the law, and the words which the LORD of hosts has sent in his spirit by the former prophets: therefore came a great wrath from the LORD of hosts.

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?
