This is what the LORD says: "About midnight I will go throughout Egypt. Every firstborn in Egypt will die, from the firstborn son of Pharaoh, who sits on the throne, to the firstborn of the slave girl, who is at her hand mill, and all the firstborn of the cattle as well. There will be loud wailing throughout Egypt—worse than there has ever been or ever will be again."
Then the Lord said to Moses, "Stretch out your hand toward the sky so that darkness will spread over Egypt—darkness that can be felt." So Moses stretched out his hand toward the sky, and total darkness covered all Egypt for three days. No one could see anyone else or leave his place for three days.
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. If you refuse to let them go, I will bring locusts into your country tomorrow. They will cover the face of the ground so that it cannot be seen. They will devour what little you have left after the hail, including every tree that is growing in your fields. They will fill your houses and those of all your officials and all the Egyptians—something neither your fathers nor your forefathers have ever seen from the day they settled in this land till now.
