Revelation 9:13-21

13Then the sixth angel blew his trumpet, and I heard a single voice coming from the horns on the golden altar that is before God,

14saying to the sixth angel, the one holding the trumpet, “Set free the four angels who are bound at the great river Euphrates!”

15Then the four angels who had been prepared for this hour, day, month, and year were set free to kill a third of humanity.

16The number of soldiers on horseback was two hundred million; I heard their number.

17Now this is what the horses and their riders looked like in my vision: The riders had breastplates that were fiery red, dark blue, and sulfurous yellow in color. The heads of the horses looked like lions’ heads, and fire, smoke, and sulfur came out of their mouths.

18A third of humanity was killed by these three plagues, that is, by the fire, the smoke, and the sulfur that came out of their mouths.

19For the power of the horses resides in their mouths and in their tails, because their tails are like snakes, having heads that inflict injuries.

20The rest of humanity, who had not been killed by these plagues, did not repent of the works of their hands, so that they did not stop worshiping demons and idols made of gold, silver, bronze, stone, and wood – idols that cannot see or hear or walk about.

21Furthermore, they did not repent of their murders, of their magic spells, of their sexual immorality, or of their stealing.
