John Trapp on Joel 2:5

Verſe 5. Like the noiſe of charets on the the tops of mountains,] Not onely on the tops of ſtanding-corn, (as other Locuſts, which therehence alſo have their name [non-Latin text not transcribed]) but as the hurry of charrets in ſtony places, Rev. 9.9. For in that book of the Revelation, the Pen-man borrows all the elegancies and flowers of the old Teſtament, thereby to ſet out the ſtory of the New in ſucceeding ages: as herehence the Popiſh Prieſts are fitly called Locuſts for their numeroſity and voracity, Rev. 9.3. They are alſo likened unto horſes (verſe 7.) fed and fierce to run, and ruſh into the battle, not without noiſe: Like the noiſe of a flame of fire that devoureth the ſtubble, Eccleſ. 7.6. Or the ratling of the jumping charet-wheels, Nahum 3.2.

as a ſtrong people ſet in battle aray,] In a bloody fight between Amurath the third, King of Turkey, and Lazarus Deſpot of Servia, many thouſands fell on both ſides. The brightneſſe of the armour, and weapons, was as it had been the lightning: the multitude of launces, and other horſemens-ſtaves ſhadowed the light of the Sun: arrows and darts fell ſo faſt, that a man would have thought they had poured down from heaven. The noiſe of the inſtruments of warre, with the neighing of horſes, and out-cries of men, was ſo terrible and great, that the wild-beaſts in the mountains ſtood aſtonied therewith:Turk. hiſt. fol. 200. and the Turkiſh Hiſtories, to expreſſe the terrour of the day, vainly ſay, that the Angels in heaven, amazed with that hideous noiſe, for that time forgot the heavenly hymns, wherewith they always glorifie God.
