¹⁷ And ^[a]this is how I saw ^(A)in the vision the horses and those who sit on them: the riders had breastplates the color of fire and of hyacinth and of ^[b](B)brimstone; and the heads of the horses are like the heads of lions; and ^(C)out of their mouths come fire and smoke and ^[c](D)brimstone. ¹⁸ A ^(E)third of ^[d]mankind was killed by these three plagues, by the ^(F)fire and the smoke and the ^[e]brimstone which came out of their mouths. ¹⁹ For the power of the horses is in their mouths and in their tails; for their tails are like serpents, having heads, and with them they do harm.
