Revelation 9:13-21

13The sixth angel blew his trumpet. From the four horns of the golden altar that is before God, I heard a voice

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

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

16The number of mounted troops was two hundred million; I heard their number.

17This is how I saw the horses and their riders in the vision: They had breastplates that were fiery red, hyacinth blue, and sulfur yellow. The heads of the horses were like the heads of lions, and from their mouths came fire, smoke, and sulfur.

18A third of the human race was killed by these three plagues — by the fire, the smoke, and the sulfur that came from their mouths.

19For the power of the horses is in their mouths and in their tails, because their tails, which resemble snakes, have heads that inflict injury.

20The rest of the people, who were not killed by these plagues, did not repent of the works of their hands to stop worshiping demons and idols of gold, silver, bronze, stone, and wood, which cannot see, hear, or walk.

21And they did not repent of their murders, their sorceries, their sexual immorality, or their thefts.
