John Trapp on Revelation 9:15

Verſe 15. And the four Angels were looſed] As fierce and fell creatures out of a cave, now ſet upon ſpoil and rapine. They have a Proverb in the Eaſtern parts, Where the great Turk once ſetteth his foot, there never grows graſſe again: He blaſts and deſolates all.

For an hour and a day] At any time whenſoever God ſhall command them out, and bid them fall on: they are at an hours warning in arms at an inſtant. Mr Brightman gathereth from this text, that the Turkiſh Empire ſhall determine about the year, 1696.

The third part of men] Mahomet the firſt was in his time the death of 800000 men. Selymus the ſecond,Turk Hiſt. fol. 434. Ibid. 885. in revenge of his loſſe received at the battle of Lepanto, would have put to death all the Chriſtians in his dominions, who were in number infinite, &c.
