Revelation 9:14-21

¹⁴ saying to the sixth angel that had the trumpet, Loose the four angels which are bound at the great river Euphrates. ¹⁵ And the four angels were loosed, who are prepared for the hour and day and month and year, that they might slay the third part of men; ¹⁶ and the number of the hosts of horse [was] twice ten thousand times ten thousand. I heard their number. ¹⁷ And thus I saw the horses in the vision, and those that sat upon them, having breastplates of fire and jacinth and brimstone; and the heads of the horses [were] as heads of lions, and out of their mouths goes out fire and smoke and brimstone. ¹⁸ By these three plagues were the third part of men killed, by the fire and the smoke and the brimstone which goes out of their mouths. ¹⁹ For the power of the horses is in their mouth and in their tails: for their tails [are] like serpents, having heads, and with them they injure. ²⁰ And the rest of men who were not killed with these plagues repented not of the works of their hands, that they should not worship demons, and the golden and silver and brazen and stone and wooden idols, which can neither see nor hear nor walk. ²¹ And they repented not of their murders, nor of their witchcrafts, nor of their fornication, nor of their thefts.
