The Lord said to Moses, “When you go to return into 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 shall not let the people go.
Then the Lord did according to the word of Moses, and He removed the swarms of flies from Pharaoh, from his servants, and from his people. Not one remained.
Then Pharaoh called for Moses and Aaron, and said, “Entreat the Lord, that He may take away the frogs from me, and from my people, and I will let the people go, so that they may sacrifice to the Lord.”
And Pharaoh sent, and behold, not one of the livestock of the Israelites was dead. But the heart of Pharaoh was hardened, so that he did not let the people go.
O Lord, why have You made us to err from Your ways and hardened our heart from fearing You? Return for Your servants’ sake, the tribes of Your inheritance.
But because of your hardness and impenitent heart, you are storing up wrath against yourself on the day of wrath when the righteous judgment of God will be revealed,
Why then do you harden your hearts, as the Egyptians and Pharaoh hardened their hearts? When He dealt severely with them, did they not let the people go, and they departed?
