[13] And the sixth angel sounded, and I heard voice from the four horns of the golden altar which is before God, [14] Saying to the sixth angel had the trumpet, Loose the four angels which are bound in the great river Euphrates. [15] And the four angels were loosed, which were prepared for an hour, and a day, and a month, and a year, for to slay the third part of men. [16] And the number of the army of the horsemen thousand and I heard the number of them. [17] And thus the horses in the vision, and them that sat on them, having breastplates of fire, and of jacinth, and brimstone: and the heads of the horses were as the heads of lions; and out of their mouths issued fire and smoke and brimstone. [18] three the third part of men killed, by the fire, and by the smoke, and by the brimstone, which issued out of their mouths. [19] For their power in their mouth, and in their tails: for their tails were like unto serpents, and had heads, and with them they do hurt.
