And the first sounded — And every angel continued to sound, till all which his trumpet brought was fulfilled and till the next began. There are intervals between the three woes, but not between the four first trumpets. And there was hail and fire mingled with blood, and there were cast upon the earth — The earth seems to mean Asia; Palestine, in particular. Quickly after the Revelation was given, the Jewish calamities under Adrian began: yea, before the reign of Trajan was ended. And here the trumpets begin. Even under Trajan, in the year 114, the Jews made an insurrection with a most dreadful fury; and in the parts about Cyrene, in Egypt, and in Cyprus, destroyed four hundred and sixty thousand persons. But they were repressed by the victorious power of Trajan, and afterward slaughtered themselves in vast multitudes. The alarm spread itself also into Mesopotamia, where Lucius Quintius slew a great number of them. They rose in Judea again in the second year of Adrian; but were presently quelled. Yet in 133 they broke out more violently than ever, under their false messiah Barcochab; and the war continued till the year 135, when almost all Judea was desolated. In the Egyptian plague also hail and fire were together. But here hail is to be taken figuratively, as also blood, for a vehement, sudden, powerful, hurtful invasion; and fire betokens the revenge of an enraged enemy, with the desolation therefrom. And they were cast upon the earth — That is, the fire and hail and blood. But they existed before they were cast upon the earth. The storm fell, the blood flowed, and the flames raged round Cyrene, and in Egypt, and Cyprus, before they reached Mesopotamia and Judea. And the third part of the earth was burnt up — Fifty well — fortified cities, and nine hundred and eighty — five well — inhabited towns of the Jews, were wholly destroyed in this war. Vast tracts of land were likewise left desolate and without inhabitant. And the third part of the trees was burned up, and all the green grass was burned up — Some understand by the trees, men of eminence among the Jews; by the grass, the common people. The Romans spared many of the former: the latter were almost all destroyed.
Thus vengeance began at the Jewish enemies of Christ's kingdom; though even then the Romans did not quite escape. But afterwards it came upon them more and more violently: the second trumpet affects the Roman heathens in particular; the third, the dead, unholy Christians; the fourth, the empire itself.
