Revelation 9:14

10They have tails like those of scorpions, with stingers. In their tails they have power to harm men for five months.

11They have over them as king the angel of the abyss. His name in Hebrew is “Abaddon”, but in Greek, he has the name “Apollyon”.

12The first woe is past. Behold, there are still two woes coming after this.

13The sixth angel sounded. I heard a voice from the horns of the golden altar which is before God,

14saying to the sixth angel who had the trumpet, “Free the four angels who are bound at the great river Euphrates!”

15The four angels were freed who had been prepared for that hour and day and month and year, so that they might kill one third of mankind.

16The number of the armies of the horsemen was two hundred million. I heard the number of them.

17Thus I saw the horses in the vision and those who sat on them, having breastplates of fiery red, hyacinth blue, and sulfur yellow; and the horses’ heads resembled lions’ heads. Out of their mouths proceed fire, smoke, and sulfur.

18By these three plagues, one third of mankind was killed: by the fire, the smoke, and the sulfur, which proceeded out of their mouths.
