Exodus 9:22-23

22Then the Lord said to Moses, “Stretch out your hand toward heaven, that there may be hail in all the land of Egypt—on man, on beast, and on every herb of the field, throughout the land of Egypt.”

23And Moses stretched out his rod toward heaven; and the Lord sent thunder and hail, and fire darted to the ground. And the Lord rained hail on the land of Egypt.
