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

¹³ And the sixth angel sounded the trumpet, and I heard one voice from the four horns of the golden altar which is before God, ¹⁴ Saying to the sixth angel who had the trumpet, Loose the four angels bound in the great river Euphrates. ¹⁵ And the four angels were loosed, prepared for an hour, and a day, and a month, and a year, that they might kill the third of men. ¹⁶ And the number of troops of cavalry, two hundred thousand thousand: and I heard their number. ¹⁷ And thus I saw the horses in the vision, and them sitting upon them, having fiery coats-of-mail, and of deep purple, and sulphurous: and the horses' heads as lions' heads; and out of their mouths went forth fire and smoke and sulphur. ¹⁸ By these three were the third of men killed, from fire, and from smoke, and from brimstone, coming forth out of their mouths. ¹⁹ For their powers are in their month, and in their tails: for their tails like serpents, having heads, and with them they injure.

²⁰ And the rest of men who were not killed by these blows, neither repented of the works of their hands, that they should not worship evil spirits, and images of gold, and silver, and brass, and stone, and wood: which neither can see, neither hear, neither walk: ²¹ And they repented not of their slaughters, nor of their charms, nor of their fornications, nor of their thefts.
