Revelation 9:18 · KJV


Context

16

And the number of the army of the horsemen were two hundred thousand thousand: and I heard the number of them.

17

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.

18

By these three was the third part of men killed, by the fire, and by the smoke, and by the brimstone, which issued out of their mouths.

19

For their power is in their mouth, and in their tails: for their tails were like unto serpents, and had heads, and with them they do hurt.

20

And the rest of the men which were not killed by these plagues yet repented not of the works of their hands, that they should not worship devils, and idols of gold, and silver, and brass, and stone, and of wood: which neither can see, nor hear, nor walk:


Commentary

KJV Study Commentary
The threefold plague (fire, smoke, brimstone) killing a third of mankind demonstrates judgment's massive scale. The fraction 'third part' appears throughout Revelation's judgments, indicating partial rather than total destruction—still leaving opportunity for repentance. These plagues parallel the Egyptian plagues' escalation. Reformed theology sees such judgments as common grace warnings; God restrains full wrath while offering space for repentance (Romans 2:4). The staggering death toll underscores sin's seriousness and coming wrath's terror. Yet the impenitent remain hardened (9:20-21), demonstrating human depravity's extent.

Historical & Cultural Context

Ancient warfare often involved burning cities and mass casualties, but this vision's scale exceeds any historical battle. The imagery communicated to first-century readers that coming judgments would surpass even Rome's devastating military campaigns. The partial nature (one-third) emphasized that these were warning judgments, not yet final consummation.

Reflection Questions

  1. How should the reality of massive death in divine judgment affect your urgency in evangelism and prayer for the lost?
  2. What does the limitation to 'a third' reveal about God's restraint even in judgment?
