King James wording
King James Version
For, behold, the LORD will come with fire, and with his chariots like a whirlwind, to render his anger with fury, and his rebuke with flames of fire.THE KEY
The LORD’s rebuke arrives as fire and force, making judgment an event that presses into the present.
THE MEANING
This verse meets you with the LORD arriving in force: fire, storm-like chariots, fury, and rebuke gathered into one scene. Its judgment carries destructive heat, and the flames do not soften the violence of the encounter.
WHAT THIS UNDOES
It undoes the belief that divine presence can only be reassuring: here the LORD’s arrival is terrifying and destructive.
THE ROOT
וְגַעֲרָתוֹ
wəgaʿărātô
GROWS FROM
גער
גער (gāʿar): to rebuke or reprove sharply.
“his rebuke” in this verse is wəgaʿărātô. The English word “rebuke” can sound like a verbal correction; here גערתו is set beside fury and flames, so the rebuke belongs to the force of the event.
ALSO GROWS
gāʿar: to rebuke, reprove
גָּעַר
The verb form shows the direct act named by the rebuke in this verse.
geʿārāh: rebuke, reproof
גְּעָרָה
This noun shares the same root and names the forceful reproof that accompanies the flames.
בְּחֵמָה
bəḥēmāh
GROWS FROM
חמם
חמם (ḥāmam): to grow hot, become warm.
חֵמָה names fury through the language of heat, and the verse immediately pairs it with flames of fire. The wording lets anger remain bodily and scorching, not merely an abstract verdict.
ALSO GROWS
ḥāmam: to become hot, grow warm
חָמַם
This verb carries the heat that is audible in the word for fury.
ḥammîm: hot, warm (masculine plural)
חַמִּים
This form keeps the same heat-family consonants, linking fury with the state of being hot.
מַרְכְּבֹתָיו
markəvōtāv
GROWS FROM
רכב
רכב (rākav): to ride or mount.
The chariots are named from the root for riding or mounting. With the whirlwind simile, the image becomes a mounted, advancing arrival carrying force into view.
ALSO GROWS
rākav: to ride, mount
רָכַב
The verb gives the action at the root of the chariot image.
rekhev: chariot, vehicle
רֶכֶב
This noun shares the root and names the vehicle carrying the arrival.
merkāvāh: chariot, carriage
מֶרְכָּבָה
This related form makes the connection between riding and the chariot explicit.
THE PATTERN
When the LORD arrives in judgment, fire and storm make the force of the encounter visible.
Our God comes, and will not hold his tongue. A fire devours before him, and a whirlwind storms fiercely all around him.Who stands before his seething? Who rises in the burning of his nostril? His heat is poured out like fire, and the rocks are torn apart by him.In flaming fire, exacting justice on those who do not perceive God and who do not hear and respond to the good news of our Lord Jesus, the Anointed One.THE THREAD
You rebuke the nations; you make the wicked lose the way; you wipe out their name for the ages and ages.The same root גער appears as גְּעָרָתוֹ, “his rebuke,” in Isaiah and גָּעַרְתָּ, “thou hast rebuked,” in the psalm. In both verses, rebuke accompanies destruction, revealing the severity carried by Isaiah’s word.
