Revelation 9:14 - Clarke's commentary and critical notes on the Bible

Saying to the sixth angel which had the trumpet, Loose the four angels which are bound in the great river Euphrates. Loose the four angels - These four angels bound - hitherto restrained, in the Euphrates, are by some supposed to be the Arabs, the Saracens, the Tartars, or the Turks; by others, Vespasian's four generals, one in Arabia, one in Africa, one in Alexandria, and one in Palestine.
