Then the sixth angel blew his trumpet, and I heard a voice speaking from the four horns of the gold altar that stands in the presence of God. And the voice said to the sixth angel who held the trumpet, “Release the four angels who are bound at the great Euphrates Rive.” Then the four angels who had been prepared for this hour and day and month and year were turned loose to kill one-third of all the people on earth. I heard the size of their army , what was 2000 million mounted troups.
And in my vision, I saw the horses and the riders sitting on them. The riders wore armor that was fiery red and dark blue and yellow. The horses had heads like lions, and fire and smoke and burning sulfur billowed from their mouths. One-third of all the people wee killed by these three plagues-by the fire and smoke and burning sulfur that came from the mouths of the horses. Their power wa in their mouths and in their tials. FOr their tails had heads like snakes, with power to injure people.
But the people who did not die in these plagues still refused to repent of their evil deeds against God. They continued to worship demons and idols made of gold, silve, bronze, stone and wood-idols that neither see nor hear nor walk! And they did not repent of their murders or their witchcraft or their sexual immorality or their thefts. (vv. 13-21, NLT)
