13And the sixth angel sounded, and I heard a voice from the horns of the golden altar which is before God, 14one saying to the sixth angel that had the trumpet, Loose the four angels that are bound at the great river Euphrates. 15And the four angels were loosed, that had been prepared for the hour and day and month and year, that they should kill the third part of men. 16And the number of the armies of the horsemen was twice ten thousand times ten thousand: I heard the number of them. 17And thus I saw the horses in the vision, and them that sat on them, having breastplates as of fire and of hyacinth and of brimstone: and the heads of the horses are as the heads of lions; and out of their mouths proceedeth fire and smoke and brimstone. 18By these three plagues was the third part of men killed, by the fire and the smoke and the brimstone, which proceeded out of their mouths. 19For the power of the horses is in their mouth, and in their tails: for their tails are like unto serpents, and have heads; and with them they hurt. 20And the rest of mankind, who were not killed with these plagues, repented not of the works of their hands, that they should not 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: 21and they repented not of their murders, nor of their sorceries, nor of their fornication, nor of their thefts.
