Revelation 9:13-21 - A Third Of Humanity Killed By Plagues
13 And the sixth angel sounded the trumpet, and I heard a voice from the four horns of the golden altar which is before the presence of God, 14 saying to the sixth angel who had the trumpet, Loose the four angels who are bound in the great river Euphrates. 15 And the four angels were loosed, who were prepared unto the hour and day and month and year, to slay the third part of men. 16 And the number of the army of the horsemen were two hundred million: and I heard the number of them. 17 And thus I saw the horses in the vision, and those that sat on them, having breastplates of fire and of jacinth and brimstone; and the heads of the horses were as the heads of lions; and out of their mouths issued fire and smoke and brimstone. 18 By these three plagues was the third part of men killed, by the fire and by the smoke and by the brimstone, which issued out of their mouths. 19 For their power is in their mouth and in their tails; for their tails were like unto serpents that have heads, and with them they do hurt.
20 And the rest of the men who were not killed by these plagues did not repent of the works of their hands, that they should not worship demons and the images of gold and of silver and of brass and of stone and of wood, which neither can see nor hear nor walk. 21 And they did not repent of their murders nor of their witchcraft nor of their fornication nor of their thefts.
