So Moses and Aaron went to Pharaoh and said, “This is what the Lord, the God of the Hebrews, says: How long will you refuse to submit to me? Let my people go, so they can worship me.
And I will harden the hearts of the Egyptians, and they will charge in after the Israelites. My great glory will be displayed through Pharaoh and his troops, his chariots, and his charioteers.
And the Lord told Moses, “When you arrive back in Egypt, go to Pharaoh and perform all the miracles I have empowered you to do. But I will harden his heart so he will refuse to let the people go.
But because you are stubborn and refuse to turn from your sin, you are storing up terrible punishment for yourself. For a day of anger is coming, when God’s righteous judgment will be revealed.
