So Moses and Aaron went to Pharaoh and said to him, “This is what Adonai, the God of the Hebrews, says: How long would you refuse to humble yourself before Me? Let My people go, so they may serve Me.
Then I, behold, I will harden the hearts of the Egyptians, and they will go in after them, so that I will be glorified over Pharaoh and all his army, his chariots and his horsemen.
Adonai said to Moses, “When you go back to Egypt, see that you do all the wonders before Pharaoh that I have put in your hand. Still, I will harden his heart, and he will not let the people go.
So the magicians said to Pharaoh, “This is the finger of God.” But Pharaoh’s heart was hardened, and he did not listen to them—just as Adonai had said.
