In Context

13 And the sixth angel sounded, and I heard a voice from the four horns of the golden altar which is before God,

14 Saying to the sixth angel who had the trumpet, Loose the four angels who are bound in the great river Euphrates.

15 And the four angels were loosed, who were prepared for an hour, and a day, and a month, and a year, to slay the third part of men.

16 And the number of the army of the horsemen was two hundred thousand thousand: and I heard the number of them.

17 And thus I saw the horses in the vision, and them that sat on them, having breast-plates of fire, and of jacinth, and brimstone: and the heads of the horses were as the heads of lions: and out of their mouths issued fire, and smoke, and brimstone.

18 By these three was the third part of men killed, by the fire, and by the smoke, and by the brimstone, which issued out of their mouths.
