And the Lord said to him as he was returning into Egypt: See that thou do all the wonders before Pharao, which I have put in thy hand. I shall harden his heart, and he will not let the people go.
He hath blinded their eyes, and hardened their heart, that they should not see with their eyes, nor understand with their heart, and be converted, and I should heal them.
And he will not hear you: and I will lay my hand upon Egypt, and will bring forth my army and my people the children of Israel out of the land of Egypt, by very great judgments.
And Moses and Aaron did all the wonders that are written, before Pharao. And the Lord hardened Pharao's heart: neither did he let the children of Israel go out of his land.
For it was the sentence of the Lord, that their hearts should be hardened, and they should fight against Israel, and fall, and should not deserve any clemency, and should be destroyed as the Lord had commanded Moses.
And Pharao sent to see: and there was not any thing dead of that which Israel possessed. And Pharao's heart was hardened, and he did not let the people go.
