Revelation 9:9-17

They had breastplates like breastplates of iron, and the sound of their wings was like the thundering of many horses and chariots rushing into battle. They had tails with stingers, like scorpions, and in their tails they had power to torment people for five months. They had as king over them the angel of the Abyss, whose name in Hebrew is Abaddon and in Greek is Apollyon (that is, Destroyer). The first woe is past; two other woes are yet to come. The sixth angel sounded his trumpet, and I heard a voice coming from the four horns of the golden 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.” And the four angels who had been kept ready for this very hour and day and month and year were released to kill a third of mankind. The number of the mounted troops was twice ten thousand times ten thousand. I heard their number. The horses and riders I saw in my vision looked like this: Their breastplates were fiery red, dark blue, and yellow as sulfur. The heads of the horses resembled the heads of lions, and out of their mouths came fire, smoke and sulfur.
