Revelation 9:12 - Joseph Benson’s Commentary on the Old and New Testaments

One wo is past, &c. This is added not only to distinguish the woes, and to mark more strongly each period, but also to suggest that some time will intervene between this first wo of the Arabian locusts and the next of the Euphratean horsemen. The similitude between the locusts and Arabians is indeed so great, that it cannot fail of striking every curious observer: and a further resemblance is noted by Mr. Daubuz, that “there had happened in the extent of this torment, a coincidence of the event with the nature of the locusts. The Saracens have made inroads into all those parts of Christendom where the natural locusts are wont to be seen, and known to do mischief, and nowhere else: and that, too, in the same proportion. Where the locusts are seldom seen, there the Saracens stayed little: where the natural locusts are often seen, there the Saracens abode most; and where they breed most, there the Saracens had their beginning and greatest power. This may be easily verified by history.”
