Revelation 9:13-21 - A Third Of Humanity Killed By Plagues

¹³ And the sixth angel sounded; and I heard one voice out of the horns of the golden altar which is before God, ¹⁴ saying to the sixth angel, who had the trumpet; "Loose the four angels that are bound in the great river Euphrates." ¹⁵ And the four angels were loosed, who had been prepared for the hour, and day, and month, and year, that they might kill the third part of men. ¹⁶ And the number of the armies of the horsemen was twice ten thousand times ten thousand: I heard the number of them. ¹⁷ And thus I saw the horses in the vision, and those who sat on them, having breastplates as of fire, and hyacinth, and brimstone. And the heads of the horses are as the heads of lions; and out of their mouths proceed fire, and smoke, and brim-stone. ¹⁸ By these three plagues the third part of men was killed, by reason of the fire, and the smoke, and the brimstone, that was issuing 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 hurt.

²⁰ And the rest of the men, who were not killed with these plagues, repented not of the works of their hands, that they should not worship the 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 repented not of their murders, nor of their sorceries, nor of their fornications, nor of their thefts.
