12 The first woe has passed, but there are two more to come.
13 Then the sixth angel blew his trumpet, and I heard a voice coming from the [four] horns of the gold altar before God,
14 telling the sixth angel who held the trumpet, “Release the four angels who are bound at the banks of the great river Euphrates.”
15 So the four angels were released, who were prepared for this hour, day, month, and year to kill a third of the human race.
16 The number of cavalry troops was two hundred million; I heard their number.
17 Now in my vision this is how I saw the horses and their riders. They wore red, blue, and yellow breastplates, and the horses’ heads were like heads of lions, and out of their mouths came fire, smoke, and sulfur.
18 By these three plagues of fire, smoke, and sulfur that came out of their mouths a third of the human race was killed.
