Isaiah 66:15

15 For lo! the Lord shall come in fire, and as a whirlwind his chariots, to yield in indignation his strong vengeance, and his blaming in the flame of fire. (For lo! the Lord shall come in fire, and his chariots like a whirlwind, to yield his strong vengeance in anger, and his rebuke in the fiery flames.)

Isaiah 66:15 Meaning and Commentary

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.

Isaiah 66:15 In-Context

13 As if a mother speaketh fair to any child (Like when a mother speaketh softly to her child), so I shall comfort you, and ye shall be comforted in Jerusalem.

14 Ye shall see, and your heart shall have joy, and your bones shall burgeon as an herb. And the hand of the Lord shall be known in his servants, and he shall have indignation to his enemies. (Ye shall see, and your heart shall have joy, and your bones shall burgeon like the herbs. And the hand, or the power, of the Lord shall be known, or shall be seen, among his servants, and he shall have anger toward his enemies.)

15 For lo! the Lord shall come in fire, and as a whirlwind his chariots, to yield in indignation his strong vengeance, and his blaming in the flame of fire. (For lo! the Lord shall come in fire, and his chariots like a whirlwind, to yield his strong vengeance in anger, and his rebuke in the fiery flames.)

16 For why the Lord shall deem in fire, and in his sword to each flesh; and slain men of the Lord shall be multiplied, (For the Lord shall judge all flesh, or all the people, with fire, and with his sword; and many people shall be killed by the Lord,)

17 that were hallowed, and guessed them clean, in gardens after one gate within; that eat swine's flesh, and abomination, and a mouse, they shall be wasted together, saith the Lord. (yea, they who were hallowed, and thought themselves to be clean, yet who go into gardens one gate within, that be dedicated to idols; and who eat swine's flesh, and mice, and other abominations, they all shall be destroyed, saith the Lord.)
