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.

And Pharaoh's heart grew hard, and he did not heed them, as the LORD had said.

So the LORD said to Moses: "Pharaoh's heart [is] hard; he refuses to let the people go.

But the LORD hardened the heart of Pharaoh; and he did not heed them, just as the LORD had spoken to Moses.

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.

"But Sihon king of Heshbon would not let us pass through, for the LORD your God hardened his spirit and made his heart obstinate, that He might deliver him into your hand, as [it is] this day.

And He said, "Go, and tell this people: 'Keep on hearing, but do not understand; Keep on seeing, but do not perceive.'

"Make the heart of this people dull, And their ears heavy, And shut their eyes; Lest they see with their eyes, And hear with their ears, And understand with their heart, And return and be healed."

Therefore they could not believe, because Isaiah said again:

"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."

Therefore He has mercy on whom He wills, and whom He wills He hardens.

And for this reason God will send them strong delusion, that they should believe the lie,

that they all may be condemned who did not believe the truth but had pleasure in unrighteousness.
