Revelation 9:10-19

10They have tails and stings like scorpions, and their power to hurt people for five months is in their tails.

11They have as king over them the angel of the bottomless pit. His name in Hebrew is Abaddon, and in Greek he is called Apollyon.

12The first woe has passed; behold, two woes are still to come.

13Then the sixth angel blew his trumpet, and I heard a voice from the four horns of the golden altar 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, the day, the month, and the year, were released to kill a third of mankind.

16The number of mounted troops was twice ten thousand times ten thousand; I heard their number.

17And this is how I saw the horses in my vision and those who rode them: they wore breastplates the color of fire and of sapphire and of sulfur, and the heads of the horses were like lions' heads, and fire and smoke and sulfur came out of their mouths.

18By these three plagues a third of mankind was killed, by the fire and smoke and sulfur coming out of their mouths.

19For the power of the horses is in their mouths and in their tails, for their tails are like serpents with heads, and by means of them they wound.
