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

¹³ And the sixth angel blew, and I heard a voice from the four corners of the golden altar, which is before God, ¹⁴ saying to the sixth angel which had the trumpet, "Loose the four angels, which are bound in the great river Euphrates." ¹⁵ And the four angels were loosed which were prepared for a hour, for a day, for a month, and for a year, for to slay the third part of men. ¹⁶ And the number of horsemen of war, were twenty times ten thousand. And I heard the number of them. ¹⁷ And thus I saw the horses in a vision, and them that sat on them, having fiery habergeons of a Jacinth colour, and brimstone, and the heads of the horses were as the heads of lions. And out of their mouths went forth fire and smoke and brimstone. ¹⁸ And of these three, was the third part of men killed, that is to say, of fire, smoke, and brimstone, which proceeded out of the mouths of them: ¹⁹ For their power was in their mouths and in their tails: for their tails were like unto serpents, and had heads, and with them they did hurt.

²⁰ And the remnant of the men which were not killed by these plagues repented not of the deeds of their hands, that they should not worship devils, and images, of gold, and silver, and brass, and stone, and of wood, which neither can see, neither hear, neither go. ²¹ Also they repented not of their murder, and of their sorcery, neither of their fornication, neither of their theft.
