Pharaoh: The man with two hearts who couldn't make up his mind.
Exodus 7 Living Bible
3 But I will cause Pharaoh to stubbornly refuse, and I will multiply my miracles in the land of Egypt. 4 Yet even then Pharaoh won’t listen to you; so I will crush Egypt with a final major disaster and then lead my people out. 5 The Egyptians will find out that I am indeed God when I show them my power and force them to let my people go.”
Exodus 8
19 “This is the finger of God,” they exclaimed to Pharaoh. But Pharaoh’s heart was hard and stubborn, and he wouldn’t listen to them, just as the Lord had predicted.
Exodus 10
27 So the Lord hardened Pharaoh’s heart and he would not let them go.
Now, Pharaoh starts changing his tune with all the plagues upon the Egyptian people:
Exodus 12
31 And Pharaoh summoned Moses and Aaron during the night and said, “Leave us; please go away, all of you; go and serve Jehovah as you said. 32 Take your flocks and herds and be gone; and oh, give me a blessing as you go.”[f] 33 And the Egyptians were urgent upon the people of Israel, to get them out of the land as quickly as possible. For they said, “We are as good as dead.”
Exodus 13
17-18 So at last Pharaoh let the people go.
The Lord hardens Pharaoh's heart another time...so the Lord will get all the honor and glory
4 And once again I will harden Pharaoh’s heart and he will chase after you. I have planned this to gain great honor and glory over Pharaoh and all his armies, and the Egyptians shall know that I am the Lord.”
If Pharaoh's heart wouldn't change so much, this would of never happened:
26 When all the Israelites were on the other side,[k] the Lord said to Moses, “Stretch out your hand again over the sea, so that the waters will come back over the Egyptians and their chariots and horsemen.” 27 Moses did, and the sea returned to normal beneath the morning light. The Egyptians tried to flee, but the Lord drowned them in the sea. 28 The water covered the path and the chariots and horsemen. And of all the army of Pharaoh that chased after Israel through the sea, not one remained alive.
