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

¹³ Then the sixth angel blew his trumpet; and I heard a voice from the horns of the golden altar which is before God, ¹⁴ one saying to the sixth angel that had the trumpet, "Loose the four angels which are bound at the great river Euphrates." ¹⁵ Then the four angels that were held in readiness for that hour and day and month and year, were let loose, to destroy a third of mankind. ¹⁶ The number of the hosts of the horsemen was twice ten thousand times ten thousand. I heard their number; ¹⁷ and thus I saw the horses in the vision and their riders. They had breastplates of fire, "red as fire, dark blue as jacinth, and yellow as sulphur." The heads of the horses were like lions' heads, and out of their mouths issued fire and smoke and brimstone. ¹⁸ By these three plagues a third of mankind were killed; by the fire and the smoke and the brimstone which issued from their mouths. ¹⁹ For the power of the horses is in their mouths and in their tails. For their tails are like serpents with heads, and with them they work woe.

²⁰ And the rest of mankind who were not killed with these plagues, did not repent of the works of their hands. They would not give up the worship of demons and of idols made of gold and silver, and brass, and stone, and 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.
