John Gill, on Isa 1:31

And the strong shall be as tow,.... "that strong one", who is eminently so; the little horn, whose look is more stout than his fellows, Dan 7:20 the beast who had great power and authority given by the dragon, Rev 13:2 who shall be cast alive into the lake of fire; when he will be like tow in those devouring flames, easily, quickly, and irrecoverably consumed, Dan 7:11, Rev 19:20. and the maker of it as a spark, or "his work"; so the Targum, "and the work of their hands shall be as a spark of fire;'' or like the embers and ashes of a coal, which are blown away and lost at once: so antichrist, and all his evil works, as well as all his evil workers under him, will be entirely consumed: or, as it may be rendered, "he that wrought him": that is, Satan, for his coming is after the working of Satan; he has his seat, power, and authority, from the dragon, the old serpent, and the devil, and may be truly called a creature of his, Th2 2:9. and they shall both burn together; both the pope and the devil in the lake of fire and brimstone, into which they will both be cast, Rev 20:10. and none shall quench them; that fire will be unquenchable and everlasting; they will be tormented for ever and ever, and so will all the worshippers of the beast, Mat 25:41. The Chaldee paraphrase is, "so the wicked shall be consumed, and their evil works, and there shall be no mercy upon them.'' Next: Isaiah Chapter 2
