Revelation 9:17-18

English Standard Version

¹⁷ And this is how I saw the horses in my vision and those who rode them: they wore breastplates the color of fire and of sapphire^[a] and of sulfur, and the heads of the horses were ^(A)like lions' heads, and fire and smoke and sulfur came out of their mouths. ¹⁸ By these three plagues a third of mankind was killed, by the fire and smoke and sulfur coming out of their mouths.
