13 The sixth angel sounded his trumpet, and I heard a voice coming from the four hornsx of the golden altar that is before God.y 14 It said to the sixth angel who had the trumpet, “Release the four angelsz who are bound at the great river Euphrates.”a 15 And the four angels who had been kept ready for this very hour and day and month and year were releasedb to kill a thirdc of mankind.d 16 The number of the mounted troops was twice ten thousand times ten thousand. I heard their number.e

17 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 mouthsf came fire, smoke and sulfur.g 18 A thirdh of mankind was killedi by the three plagues of fire, smoke and sulfurj that came out of their mouths. 19 The power of the horses was in their mouths and in their tails; for their tails were like snakes, having heads with which they inflict injury.

20 The rest of mankind who were not killed by these plagues still did not repentk of the work of their hands;l they did not stop worshiping demons,m and idols of gold, silver, bronze, stone and wood—idols that cannot see or hear or walk.n 21 Nor did they repento of their murders, their magic arts,p their sexual immoralityq or their thefts.
