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

¹³ Then the sixth angel sounded his trumpet, and I heard a voice from the four horns of the golden altar which is before God, ¹⁴ saying to the sixth angel who had the trumpet, "Release the four angels who are bound at the great river Euphrates." ¹⁵ And the four angels, who had been held ready for the hour and day and month and year, were released to kill a third of mankind. ¹⁶ The number of the troops of cavalry was two hundred million; I heard their number. ¹⁷ And this was how I saw the horses in my vision: the riders wore breastplates the color of fire and of sapphire and of sulfur, and the heads of the horses were like the heads of lions, and out of their mouths came fire and smoke and sulfur. ¹⁸ A third of mankind was killed by these three plagues, by the fire and the smoke and sulfur that came out of their mouths. ¹⁹ For 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.

²⁰ The rest of mankind, who were not killed by these plagues, did not repent of the works of their hands nor give up worshipping demons and idols of gold and silver and bronze and stone and wood, which can neither see nor hear nor walk; ²¹ nor did they repent of their murders, their sorceries, their sexual immorality or their thefts.
