Revelation 9:17

American Standard Version (ASV):
And thus I saw the horses in the vision, and them that sat on them, having breastplates [as] of fire and of hyacinth and of brimstone: and the heads of lions; and out of their mouths proceedeth fire and smoke and brimstone.

King James Version (KJV):
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.
