Moses and Aaron went to Pharaoh and said to him, “GOD, the God of the Hebrews, says, ‘How long are you going to refuse to knuckle under? Release my people so that they can worship me. If you refuse to release my people, watch out; tomorrow I’m bringing locusts into your country. They’ll cover every square inch of ground; no one will be able to see the ground. They’ll devour everything left over from the hailstorm, even the saplings out in the fields—they’ll clear-cut the trees. And they’ll invade your houses, filling the houses of your servants, filling every house in Egypt. Nobody will have ever seen anything like this, from the time your ancestors first set foot on this soil until today.’”
Then he turned on his heel and left Pharaoh.
