Revelation 9
17 Ref And so I saw the horses in the vision, and those who were seated on them, having breastplates of fire and glass and of burning stone: and the heads of the horses were as the heads of lions; and out of their mouths came fire and smoke and a smell of burning.
18 Ref By these evils a third part of men was put to death, by the fire, and the smoke, and the burning smell which came out of their mouths.
