And the LORD said unto Moses, When thou goest to return into Egypt, see that thou do all those wonders before Pharaoh, which I have put in thine hand: but I will harden his heart, that he shall not let the people go.

And he hardened Pharaoh's heart, that he hearkened not unto them; as the LORD had said. And the LORD said unto Moses, Pharaoh's heart is hardened, he refuseth to let the people go.

But my people would not hearken to my voice; and Israel would none of me. So I gave them up unto their own hearts' lust: and they walked in their own counsels.

And the fifth angel poured out his vial upon the seat of the beast; and his kingdom was full of darkness; and they gnawed their tongues for pain, And blasphemed the God of heaven because of their pains and their sores, and repented not of their deeds.
