Revelation 9:16

9:15 So the four angels, who had been prepared for the hour and day and month and year, were released to kill a third of mankind.

9:16 Now the number of the army of the horsemen was two hundred million; I heard the number of them.

9:17 And thus I saw the horses in the vision: those who sat on them had breastplates of fiery red, hyacinth blue, and sulfur yellow; and the heads of the horses were like the heads of lions; and out of their mouths came fire, smoke, and brimstone.
