14 Saying to the sixth angel who had the trumpet, Liberate the four angels who are bound at the great river Euphrates.
15 So the four angels who had been in readiness for that hour in the appointed day, month, and year were liberated to destroy a third of mankind.
16 The number of their troops of cavalry was twice ten thousand times ten thousand (200,000,000); I heard what their number was.
17 And in [my] vision the horses and their riders appeared to me like this: the riders wore breastplates the color of fiery red and sapphire blue and sulphur (brimstone) yellow. The heads of the horses looked like lions' heads, and from their mouths there poured fire and smoke and sulphur (brimstone).
18 A third of mankind was killed by these three plagues–by the fire and the smoke and the sulphur (brimstone) that poured from the mouths of the horses.
19 For the power of the horses to do harm is in their mouths and also in their tails. Their tails are like serpents, for they have heads, and it is by means of them that they wound people.
20 And the rest of humanity who were not killed by these plagues even then did not repent of [the worship of] the works of their [own] hands, so as to cease paying homage to the demons and idols of gold and silver and bronze and stone and wood, which can neither see nor hear nor move. [Ps. 115:4-7; 135:15-17; Isa. 17:8.]
