Revelation 9:14-21

¹⁴ one saying to the sixth angel who had the trumpet , "Release the four angels who are bound at the great river Euphrates ." ¹⁵ And the four angels , who had been prepared for the hour and day and month and year , were released , so that they would kill a third of mankind . ¹⁶ The number of the armies of the horsemen was two e hundred e million e ; I heard the number of them. ¹⁷ And this is how I saw in the vision the horses and those who sat on them: the riders had breastplates the color of fire and of hyacinth and of brimstone ; and the heads of the horses are like the heads of lions ; and out of their mouths proceed fire and smoke and brimstone . ¹⁸ A third of mankind was killed by these three plagues , by the fire and the smoke and the brimstone which proceeded 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 and have heads , and with them they do harm . ²⁰ The rest of mankind , who were not killed by these plagues , did not repent of the works of their hands , so as not to worship demons , and the idols of gold and of silver and of brass and of stone and of wood , which can neither see nor hear nor walk ; ²¹ and they did not repent of their murders nor of their sorceries nor of their immorality nor of their thefts .
