The seventh plague of Egypt was a destructive storm. God commanded Moses to stretch his staff skyward, at which point the storm commenced. It was even more evidently supernatural than the previous plagues, a powerful shower of hail intermixed with fire. The storm heavily damaged Egyptian orchards and crops, as well as men and livestock. The storm struck all of Egypt except for the Land of Goshen. Pharaoh asked Moses to remove this plague and promised to allow the Israelites to worship God in the desert, saying "This time I have sinned; God is righteous, I and my people are wicked." As a show of God's mastery over the world, the hail stopped as soon as Moses began praying to God - hail which was then in the air never reached the ground; it simply disappeared. However, after the storm ceased, Pharaoh "hardened his heart" and refused to keep his promise.
