Why then do you harden your hearts as the Egyptians and Pharaoh hardened their hearts? When he had worked wonderfully amongst them, didn’t they let the people go, and they departed?
Moses and Aaron went in to Pharaoh, and said to him, “This is what the LORD, the God of the Hebrews, says: ‘How long will you refuse to humble yourself before me? Let my people go, that they may serve me.
Behold, I myself will harden the hearts of the Egyptians, and they will go in after them. I will get myself honour over Pharaoh, and over all his armies, over his chariots, and over his horsemen.
The LORD said to Moses, “When you go back into Egypt, see that you do before Pharaoh all the wonders which I have put in your hand, but I will harden his heart and he will not let the people go.
But according to your hardness and unrepentant heart you are treasuring up for yourself wrath in the day of wrath, revelation, and of the righteous judgement of God,
