Revelation 9:17 Revelation 9:17 And thus I saw 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. Here we have a metaphorical and mystical description of the horsemen, and the horses. The horsemen had breast-plates of fire, and jacinth, and brimstone. By their breast-plates of fire, we may understand their bright shining armour; and by jacinth, is figured and set forth the jewels and riches of the Turkish camp and the commanders, who had costly jewels and pearls about them; and their embroidered rich garments were of fiery, sulphurous colour, like brimstone, whitely yellow. The heads of the horses were as the heads of lions; that is, very formidable and terrible, very bold and fierce. And out of their mouths issued fire, and smoke, and brimstone; which signifies the Turkish fiery armies, canons, muskets, pistols, etc.
