And the sixth angel sounded:
I heard a voice from the four corners of the golden altar which is before God, saying to the angel: “Free the four angels who are bound at the Euphrates!” They were freed and were prepared for that hour and day and month and year, to kill one third of mankind. The number of the armies of the horsemen was many thousand times thousand. I heard the number of them. And they that sat on them had fiery, sulfur yellow and blue breastplates. The horses had heads like lions. Out of their mouths came fire, smoke and sulfur. The tails were like snakes. And those that were not killed still worshiped the idols. They didn’t repent of their murders, their sorceries, their sexual immorality, or their thefts.
