Exodus 9:24-28

So there was hail, and fire mingled with the hail, very grievous, such as had not been in all the land of Egypt since it became a nation. And the hail smote throughout all the land of Egypt all that was in the field, both man and beast; and the hail smote every herb of the field, and brake every tree of the field. Only in the land of Goshen, where the children of Israel were, was there no hail. And Pharaoh sent, and called for Moses and Aaron, and said unto them, I have sinned this time: Jehovah is righteous, and I and my people are wicked. Entreat Jehovah; for there hath been enough of these mighty thunderings and hail; and I will let you go, and ye shall stay no longer.
