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

¹³ Then the sixth angel blew; and I heard a voice from the four horns of the golden altar before God, ¹⁴ telling the sixth angel with the trumpet, "Let loose the four angels who are bound at the great river Euphrates." ¹⁵ So the four angels were unloosed, who had been kept ready for that hour and day and month and year, to kill the third of men. ¹⁶ And the number of the troops of their cavalry was two hundred millions (I heard what was their number). ¹⁷ And this is how the horses and their riders looked in my vision: they wore coats of mail red as fire, dark-blue as jacinth and yellow as smoke; the horses' heads were like lions' heads, and from their mouths poured fire and smoke and brimstone. ¹⁸ By these three plagues the third of men were killed, by the fire, the smoke, and the brimstone, that poured out of their mouths; ¹⁹ for the power of the horses lies in their mouths ??and also in their tails (their tails are like serpents, they have heads, and it is with their heads that they hurt).

²⁰ But the rest of mankind, who were not killed by these plagues, did not repent of the works of their hands and give up worshipping daemons and idols of gold and silver and brass and stone and wood, which cannot either see or hear or stir; ²¹ nor did they repent of their murders or of their magic spells or of their sexual vice or of their thefts.
