Then the sixth angel blew his trumpet, and I heard a voice from the four horns of the gold altar that is before God.
It said to the sixth angel, who had the trumpet, "Release the four angels who are bound at the great river Euphrates."
Then the four angels who had been made ready for that hour, day, month, and year were released to kill a third of humankind.
The number of cavalry troops was two hundred million. I heard their number.
And this is the way I saw the horses and their riders in the vision: they had breastplates that were fiery red, dark blue, and yellow as sulfur. The horses' heads were like lions' heads, and out of their mouths came fire, smoke, and sulfur.
By these three plagues a third of humankind was killed: by the fire, smoke, and sulfur coming out of their mouths.
The horses' power is in their mouths and their tails, for their tails are like snakes with heads that inflict injuries.
The rest of humankind, who weren't killed by these plagues, didn't change their hearts and lives and turn from their handiwork. They didn't stop worshipping demons and idols made of gold, silver, bronze, stone, and wood—idols that can't see or hear or walk.
They didn't turn away from their murders, their spells and drugs, their sexual immorality, or their stealing.
