And the Lord said to Moses, Go in to Pharaoh: for I have made his heart and the hearts of his servants hard, so that I may let my signs be seen among them:
All these wonders Moses and Aaron did before Pharaoh: but the Lord made Pharaoh's heart hard, and he did not let the children of Israel go out of his land.
And the Lord said to Moses, When you go back to Egypt, see that you do before Pharaoh all the wonders which I have given you power to do: but I will make his heart hard and he will not let the people go.
But Pharaoh will not give ear to you, and I will put my hand on Egypt, and take my armies, my people, the children of Israel, out of Egypt, after great punishments.
And Pharaoh sent and got word that there was no loss of any of the cattle of Israel. But the heart of Pharaoh was hard and he did not let the people go.
He has made their eyes blind, and their hearts hard; for fear that they might see with their eyes and get knowledge with their hearts, and be changed, and I might make them well.
For the Lord made them strong in heart to go to war against Israel, so that he might give them up to the curse without mercy, and that destruction might come on them, as the Lord had given orders to Moses.
