Isaiah 66:15

For, behold, the Lord will come with fire
Either with material fire, with which mystical Babylon or Rome shall be burnt, ( Revelation 18:8 ) , or with indignation and wrath, which shall be poured out like fire, and be as intolerable and consuming as that: and with his chariots like a whirlwind;
making a great noise, and striking great terror; alluding to chariots in which men used formerly to fight: to render his anger with fury, and his rebuke with flames of fire;
a heap of words, to show the fierceness of his wrath, and how severe his rebuke of enemies will be; which will be not a rebuke in love, as of his own people, but in a way of vindictive wrath.
