BLB(i)
13 And the sixth angel sounded his trumpet, and I heard one voice from the four horns of the golden altar before God,
14 saying to the sixth angel, the one having the trumpet, “Release the four angels, those having been bound at the great river Euphrates.”
15 And the four angels having been prepared for the hour and day and month and year were released, so that they might kill a third of mankind.
16 And the number of the armies of the cavalry was twice ten thousand ten thousands; I heard the number of them.
17 And thus I saw the horses in the vision, and those sitting on them, having fiery and hyacinthine and brimstone breastplates. And the heads of the horses were like heads of lions, and out of their mouths proceed fire and smoke and brimstone.
18 By these three plagues, a third of mankind was killed, by the fire, and by the smoke, and by the brimstone proceeding out of their mouths.
19 For the powers of the horses are in their mouths and in their tails; for their tails are like serpents having heads, and with them they injure.
20 And the rest of the men who were not killed by these plagues did not even repent of the works of their hands so that they will not worship the demons, and the golden and silver and bronze and stone and wooden idols, which are able neither to see, nor to hear, nor to walk.
21 And they did not repent of their murders, nor of their sorceries, nor of their sexual immorality, nor of their thefts.
