Exodus 9:22-24

The LORD told Moses, “Raise your hand toward the sky. Then the hail will start falling in all the land of Egypt. It will fall on people, animals, and on everything that grows in the fields of Egypt.” When Moses raised his walking stick toward the sky, the LORD sent thunder and hail, and lightning flashed down to the earth. So he caused hail to fall upon the land of Egypt. There was hail, and lightning flashed as it hailed—the worst hailstorm in Egypt since it had become a nation.
