Isaiah 66:15
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. 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 Lord will come with fire, and with His chariots like a whirlwind. In that coming He renders His anger with fury and His rebuke with flames of fire. In its setting this judgment falls on those who eat swine's flesh and other forbidden things. The warning applies to the close of the present age.
