Exodus 9:23-25

23When Moses stretched out his staff toward the sky, the Lord sent thunder and hail, and lightning flashed down to the ground. So the Lord rained hail on the land of Egypt; 24hail fell and lightning flashed back and forth. It was the worst storm in all the land of Egypt since it had become a nation. 25Throughout Egypt hail struck everything in the fields—both people and animals; it beat down everything growing in the fields and stripped every tree.
