There is no need to spiritualize this. It means just what it says. These things have happened before why not again? It is the fulfilment of Joel 2:30-31, where the Lord says that in the "latter days" He will--"Shew wonders in the heavens' and in the earth, BLOOD, and FIRE, and PILLARS OF SMOKE. The sun shall be turned into DARKNESS, and the Moon into BLOOD, before the GREAT AND THE TERRIBLE DAY OF THE LORD COME." The DAY when He shall come to take VENGEANCE ON HIS ENEMIES. The Lord is going to repeat the "PLAGUES OF EGYPT." They were literal, why not the "Trumpet" and "Vial" Judgments? The literalness of these Judgments give us the "key" to the LITERALNESS of the Book of Revelation. No less than 5 of the 9 Plagues of Egypt are to be repeated during the Tribulation Period. This Plague is the same as the "SEVENTH EGYPTIAN PLAGUE." "And 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." And 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. So 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. 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." Ex. 9:22-26. The difference between this Egyptian Plague, and the Plague of the First Trumpet, is, that the situation will be reversed. Then the "CHILDREN OF ISRAEL" escaped, now they will suffer. The Judgments of Egypt were directed against Pharoah, the Judgments of the Tribulation Period will be directed against Israel.
The Egyptian "Plague of Hail" was clearly a great "ELECTRICAL STORM" that did not touch the Land of Goshen where the Children of Israel dwelt. The FIRE that "ran along the ground" was lightning. The difference between the Egyptian Plague and the one John describes is, that in Egypt man and beast suffered with the vegetation, while only the trees and the green grass will suffer when the First Trumpet sounds, and the HAIL and FIRE will be MINGLED WITH BLOOD. In Egypt the "Hail" smote every herb of the field, and broke every tree, but under the First Trumpet only one-third of the trees and grass will be burnt up.
