Revelation 9:10-19

10They had tails like scorpions, and there were stings in their tails. Their power was to hurt men five months.

11And they had as king over them the angel of the bottomless pit, whose name in Hebrew is Abaddon, but in Greek he has the name Apollyon.

12One woe is past. Behold, still two more woes are coming after these things.

13Then the sixth angel sounded: And I heard a voice from the four horns of the golden altar which is before God,

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

15So the four angels, who had been prepared for the hour and day and month and year, were released to kill a third of mankind.

16Now the number of the army of the horsemen was two hundred million; I heard the number of them.

17And thus I saw the horses in the vision: those who sat on them had breastplates of fiery red, hyacinth blue, and sulfur yellow; and the heads of the horses were like the heads of lions; and out of their mouths came fire, smoke, and brimstone.

18By these three plagues a third of mankind was killed—by the fire and the smoke and the brimstone which came out of their mouths.

19For their power is in their mouth and in their tails; for their tails are like serpents, having heads; and with them they do harm.
