Revelation 9:15-21

15And the four angels, who had been prepared for the hour and day and month and year, were 1released, so that they would kill a 2third of mankind. 16The number of the armies of the horsemen was 3two hundred million; 4I heard the number of them. 17And this is how I saw 5in my vision the horses and those who sat on them: the riders had breastplates the color of fire, of hyacinth, and of 67brimstone; and the heads of the horses are like the heads of lions; and 8out of their mouths came fire and smoke and 910brimstone. 18A 11third of mankind was killed by these three plagues, by the 12fire, the smoke, and the 13brimstone which came out of their mouths. 19For 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.

20The rest of mankind, who were not killed by these plagues, 14did not repent of 15the works of their hands so as not to 16worship demons and 17the idols of gold, silver, brass, stone, and wood, which can neither see nor hear nor walk; 21and they 18did not repent of their murders, nor of their 19witchcraft, nor of their 20sexual immorality, nor of their thefts.
