13 Then the sixth angel blew his trumpet, and I heard a voice from lthe four horns of the golden altar before God, 14 saying to the sixth angel who had the trumpet, “Release mthe four angels who are bound at nthe great river Euphrates.” 15 So the four angels, who had been prepared for the hour, the day, the month, and the year, were released oto kill a third of mankind. 16 The number of pmounted troops was qtwice ten thousand times ten thousand; rI heard their number. 17 And this is how I saw the horses in my vision and those who rode them: they wore breastplates the color of fire and of sapphire3 and of sulfur, and the heads of the horses were slike lions’ heads, and fire and smoke and sulfur came out of their mouths. 18 By these three plagues a third of mankind was killed, by the fire and smoke and sulfur coming out of their mouths. 19 For the power of the horses is in their mouths and in their tails, for their tails are like serpents with heads, and by means of them they wound.
