In Exodus God stated that he would harden Pharaoh's heart. The Scripture also records Pharaoh as hardening his own heart. 15 But when Pharaoh saw that there was relief, he hardened his heart and would not listen to Moses and Aaron, just as the LORD had said. (ch. 8) 3 But I will harden Pharaoh's heart, and though I multiply my miraculous signs and wonders in Egypt, 4 he will not listen to you. Then I will lay my hand on Egypt and with mighty acts of judgment I will bring out my divisions, my people the Israelites. 5 And the Egyptians will know that I am the LORD when I stretch out my hand against Egypt and bring the Israelites out of it." (ch.7) In Genesis 8:21, God stated that every inclination of the human heart is only evil all the time. Jeremiah 17:9 stated that the human heart is deceitful above all things. 3 This is the evil in everything that happens under the sun: The same destiny overtakes all. The hearts of men, moreover, are full of evil and there is madness in their hearts while they live, and afterward they join the dead. (Ecclesiastes) One belief is that Pharaoh must have had some goodness in his heart or God would not need to harden it. Could it be that by hardening, God simply allowed Pharaoh to do what his heart full of madness desperately wanted to do?
