Revelation 9:14 Revelation 9:14 Saying to the sixth angel which had the trumpet, Loose the four angels which are bound in the great river Euphrates. By these four Angels, we may understand the chief commanders of the armies of the Turkish emperor, for they consisted of four several sorts of people, that is, Arabians, Saracens, Tartars and Turks, whose four Souldans in Asia, Aleppo, Damascus, and Antioch, (as historians tell us) had their chief residence near the river Euphrates, and were bounded by that great river, from coming over into Europe. And now God gave them permission to pass over that great river with their armies, who destroyed the third party of the then Roman Empire, as the Turkish history, and the holy war relate unto us.
