And the Lord said to Moses, “When you go back to Egypt, see that you do all those wonders before Pharaoh which I have put in your hand. But I will harden his heart, so that he will not let the people go.
“He has blinded their eyes and hardened their hearts, Lest they should see with their eyes, Lest they should understand with their hearts and turn, So that I should heal them.”
But Pharaoh will not heed you, so that I may lay My hand on Egypt and bring My armies and My people, the children of Israel, out of the land of Egypt by great judgments.
Now the Lord said to Moses, “Go in to Pharaoh; for I have hardened his heart and the hearts of his servants, that I may show these signs of Mine before him,
So Moses and Aaron did all these wonders before Pharaoh; and the Lord hardened Pharaoh’s heart, and he did not let the children of Israel go out of his land.
For it was of the Lord to harden their hearts, that they should come against Israel in battle, that He might utterly destroy them, and that they might receive no mercy, but that He might destroy them, as the Lord had commanded Moses.
Then Pharaoh sent, and indeed, not even one of the livestock of the Israelites was dead. But the heart of Pharaoh became hard, and he did not let the people go.
