Why do you harden your hearts as the Egyptians and Pharaoh did? When Israel’s god dealt harshly with them, did they not send the Israelites out so they could go on their way?
So Moses and Aaron went to Pharaoh and said to him, “This is what the Lord, the God of the Hebrews, says: ‘How long will you refuse to humble yourself before me? Let my people go, so that they may worship me.
I will harden the hearts of the Egyptians so that they will go in after them. And I will gain glory through Pharaoh and all his army, through his chariots and his horsemen.
The Lord said to Moses, “When you return to Egypt, see that you perform before Pharaoh all the wonders I have given you the power to do. But I will harden his heart so that he will not let the people go.
But because of your stubbornness and your unrepentant heart, you are storing up wrath against yourself for the day of God’s wrath, when his righteous judgment will be revealed.
