Exodus 8:15
"When Pharaoh saw that there was relief, however, he hardened his heart and would not listen to Moses and Aaron, just as the LORD had said."
1 Samuel 6:6
"Why harden your hearts as the Egyptians
and Pharaoh hardened theirs? When He afflicted them, did they not send the people on their way as they departed?"
It seems like a combination of God and Pharaoh here. God knew Pharaoh would harden his own heart so, God gave him up to a hard heart to serve His own purposes perhaps?[/QUOTE]
Exodus 6:2-4
2 God spoke further to Moses and said to him, “I am the Lord; 3 and I appeared to Abraham, Isaac, and Jacob, as God Almighty, but by My name, Lord, I did not make Myself known to them. 4 I also established My covenant with them, to give them the land of Canaan, the land in which they sojourned.
Beginning with Moses, God began to reveal himself as the transcendent creator. The passage I quoted above indicates this transition, though it is a bit difficult to see it, given this translation. His name is "Lord", which in Hebrew is "Yahweh". The NET Bible explains it this way.
The announcement “I am the Lord” (Heb “Yahweh”) draws in the preceding revelation in Exod 3:15. In that place God called Moses to this task and explained the significance of the name “Yahweh” by the enigmatic expression “I am that I am.” “I am” (אֶהְיֶה, ʾehyeh) is not a name; “Yahweh” is. But the explanation of the name with this sentence indicates that Yahweh is the one who is always there, and that guarantees the future, for everything he does is consistent with his nature. He is eternal, never changing; he remains. Now, in Exodus 6, the meaning of the name “Yahweh” will be more fully unfolded.
In other words, while Abraham, being a polytheist, knew God as El Shaddai, "God almighty", the God that rules all gods, beginning with Moses, God will reveal himself as "Yahweh", "he who is" or "I am that I am", the one who is always there and the one who guarantees the future. He is not merely the strongest god within our reality; he is the God that exists at a higher plane of existence such that he is the source of everything that exists, including history.
I agree with you; there is a combination of God and Pharaoh here. But the combination is not as you suggest, which understands God to be on the same plane of reality as Pharaoh. With Moses, God begins to reveal his true nature as the transcendent creator. Abraham knew him to be the greatest, most powerful God in all of reality. So powerful, in fact, that he believed God could bring Isaac back from the dead, according to Paul the apostle. God tells Moses, now I am going to reveal myself as "the one who creates everything including history."
The Lord said to Moses, “When you go back to Egypt see that you perform before Pharaoh all the wonders which I have put in your power; but I will harden his heart so that he will not let the people go.
When we remember this event, we tend to remember the event this way. It pleased God almighty to free an enslaved people and set them free. And in order to do this he coerced Pharaoh to comply through a series of plagues, and in the process, he demonstrated his mighty power. But God actually told Moses, I am going to send you to perform miracles before Pharaoh, but in the mean time I will harden his heart. Why did he do it that way?
While we remember the event in terms of the most powerful God freeing the slaves, in fact, the Exodus story is a prime example of Yahweh's nature as the one who writes history. God doesn't tell Moses, "I predict that Pharaoh will harden his heart." Rather, he tells Moses, "I will harden his heart so that he will not let the people go. On purpose. I don't want Pharaoh to let the people go. The purpose of the plagues wasn't to coerce or force Pharaoh to comply. He tells Moses that he will make sure that Pharaoh doesn't comply. The people will not be freed until God is ready to release them. It was God's will that Pharaoh have a hard heart and refuse to let the people go, even in light of the most awful circumstances.
Finally, we have a New Testament reference to the fact that God creates history to his liking.
Hebrews 1:1-2
1 God, after He spoke long ago to the fathers in the prophets in many portions and in many ways, 2 in these last days has spoken to us in His Son, whom He appointed heir of all things, through whom also He made the world.
The word translated "world" in this context is "ages", indicating history. Paul says that God creates history.
