13. The sixth angel trumpeted, and I heard a single voice from the four horns of the golden altar before God.
14. It said to the sixth angel, the one holding the trumpet, “Release the four angels who are bound at the great river Euphrates.”
15. So the four angels—who had been prepared for the hour and day and month and year—were released to kill a third of mankind.
16. The number of mounted troops was two hundred million—I heard their number.
17. Now here is how I saw the horses and those riding on them: they had breastplates that were fiery red, hyacinth blue, and sulfur yellow. The heads of the horses were as heads of lions, and out of their mouths came fire and smoke and brimstone.
18. By these three plagues a third of mankind was killed—by the fire and the smoke and the brimstone that came out of their mouths.
19. For the power of the horses is in their mouths and in their tails; for their tails are like serpents, having heads by which they inflict injuries.
20. But the rest of mankind, those not killed by these plagues, did not repent and turn away from the works of their hands—they would not stop worshiping demons and the idols of gold and silver and stone and wood, which cannot see or hear or walk.
21. And they did not repent and turn away from their murders or their sorceries or their sexual immorality or their stealing.
