Hail

Boyd’s Bible Dictionary:

The seventh plague
(Ex. 9:18-2918Behold, to morrow about this time I will cause it to rain a very grievous hail, such as hath not been in Egypt since the foundation thereof even until now. 19Send therefore now, and gather thy cattle, and all that thou hast in the field; for upon every man and beast which shall be found in the field, and shall not be brought home, the hail shall come down upon them, and they shall die. 20He that feared the word of the Lord among the servants of Pharaoh made his servants and his cattle flee into the houses: 21And he that regarded not the word of the Lord left his servants and his cattle in the field. 22And the Lord said unto Moses, Stretch forth thine hand toward heaven, that there may be hail in all the land of Egypt, upon man, and upon beast, and upon every herb of the field, throughout the land of Egypt. 23And Moses stretched forth his rod toward heaven: and the Lord sent thunder and hail, and the fire ran along upon the ground; and the Lord rained hail upon the land of Egypt. 24So there was hail, and fire mingled with the hail, very grievous, such as there was none like it in all the land of Egypt since it became a nation. 25And 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. 26Only in the land of Goshen, where the children of Israel were, was there no hail. 27And Pharaoh sent, and called for Moses and Aaron, and said unto them, I have sinned this time: the Lord is righteous, and I and my people are wicked. 28Entreat the Lord (for it is enough) that there be no more mighty thunderings and hail; and I will let you go, and ye shall stay no longer. 29And Moses said unto him, As soon as I am gone out of the city, I will spread abroad my hands unto the Lord; and the thunder shall cease, neither shall there be any more hail; that thou mayest know how that the earth is the Lord's. (Exodus 9:18‑29)). God’s weapon (Josh. 10:1111And it came to pass, as they fled from before Israel, and were in the going down to Beth-horon, that the Lord cast down great stones from heaven upon them unto Azekah, and they died: they were more which died with hailstones than they whom the children of Israel slew with the sword. (Joshua 10:11); Rev. 16:2121And there fell upon men a great hail out of heaven, every stone about the weight of a talent: and men blasphemed God because of the plague of the hail; for the plague thereof was exceeding great. (Revelation 16:21)).

Particles of ice falling from the clouds. Though hail is usually formed by natural causes not yet perhaps well understood, it is often referred to in scripture as one of the judgments of God. It formed one of the plagues in Egypt (Ex. 9:18-3418Behold, to morrow about this time I will cause it to rain a very grievous hail, such as hath not been in Egypt since the foundation thereof even until now. 19Send therefore now, and gather thy cattle, and all that thou hast in the field; for upon every man and beast which shall be found in the field, and shall not be brought home, the hail shall come down upon them, and they shall die. 20He that feared the word of the Lord among the servants of Pharaoh made his servants and his cattle flee into the houses: 21And he that regarded not the word of the Lord left his servants and his cattle in the field. 22And the Lord said unto Moses, Stretch forth thine hand toward heaven, that there may be hail in all the land of Egypt, upon man, and upon beast, and upon every herb of the field, throughout the land of Egypt. 23And Moses stretched forth his rod toward heaven: and the Lord sent thunder and hail, and the fire ran along upon the ground; and the Lord rained hail upon the land of Egypt. 24So there was hail, and fire mingled with the hail, very grievous, such as there was none like it in all the land of Egypt since it became a nation. 25And 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. 26Only in the land of Goshen, where the children of Israel were, was there no hail. 27And Pharaoh sent, and called for Moses and Aaron, and said unto them, I have sinned this time: the Lord is righteous, and I and my people are wicked. 28Entreat the Lord (for it is enough) that there be no more mighty thunderings and hail; and I will let you go, and ye shall stay no longer. 29And Moses said unto him, As soon as I am gone out of the city, I will spread abroad my hands unto the Lord; and the thunder shall cease, neither shall there be any more hail; that thou mayest know how that the earth is the Lord's. 30But as for thee and thy servants, I know that ye will not yet fear the Lord God. 31And the flax and the barley was smitten: for the barley was in the ear, and the flax was bolled. 32But the wheat and the rie were not smitten: for they were not grown up. 33And Moses went out of the city from Pharaoh, and spread abroad his hands unto the Lord: and the thunders and hail ceased, and the rain was not poured upon the earth. 34And when Pharaoh saw that the rain and the hail and the thunders were ceased, he sinned yet more, and hardened his heart, he and his servants. (Exodus 9:18‑34); Psa. 78:47-4847He destroyed their vines with hail, and their sycomore trees with frost. 48He gave up their cattle also to the hail, and their flocks to hot thunderbolts. (Psalm 78:47‑48); Psa. 105:3232He gave them hail for rain, and flaming fire in their land. (Psalm 105:32)); and is at times connected with fire or lightning. God smote the Amalekites by “great stones” from heaven (Josh. 10:1111And it came to pass, as they fled from before Israel, and were in the going down to Beth-horon, that the Lord cast down great stones from heaven upon them unto Azekah, and they died: they were more which died with hailstones than they whom the children of Israel slew with the sword. (Joshua 10:11)). The hail is called upon to praise Jehovah, because it fulfills His word (Psa. 148:88Fire, and hail; snow, and vapor; stormy wind fulfilling his word: (Psalm 148:8); Isa. 28:2,172Behold, the Lord hath a mighty and strong one, which as a tempest of hail and a destroying storm, as a flood of mighty waters overflowing, shall cast down to the earth with the hand. (Isaiah 28:2)
17Judgment also will I lay to the line, and righteousness to the plummet: and the hail shall sweep away the refuge of lies, and the waters shall overflow the hiding place. (Isaiah 28:17); Hag. 2:1717I smote you with blasting and with mildew and with hail in all the labors of your hands; yet ye turned not to me, saith the Lord. (Haggai 2:17)). It will also form a notable part of the judgments of God in His future dealings with this guilty world (Rev. 8:77The first angel sounded, and there followed hail and fire mingled with blood, and they were cast upon the earth: and the third part of trees was burnt up, and all green grass was burnt up. (Revelation 8:7); Rev. 11:1919And the temple of God was opened in heaven, and there was seen in his temple the ark of his testament: and there were lightnings, and voices, and thunderings, and an earthquake, and great hail. (Revelation 11:19); Rev. 16:2121And there fell upon men a great hail out of heaven, every stone about the weight of a talent: and men blasphemed God because of the plague of the hail; for the plague thereof was exceeding great. (Revelation 16:21)).
