isaiah 65:25 The wolf and the lamb shall feed together, and the lion shall eat straw like the bullock: and dust shall be the serpent's meat. They shall not hurt nor destroy in all my holy mountain, saith the LORD. - Free Bible Online

      25. (See on Isa 11:6).
      and the lion shall eat straw like the bullock--(See on Isa 11:7).
      and dust--rather, "but dust," &c. The curse shall remain on the serpent [HORSLEY], (Ge 3:14; Mic 7:17). "To lick the dust" is figurative of the utter and perpetual degradation of Satan and his emissaries (Isa 49:23; Ps 72:9). Satan fell self-tempted; therefore no atonement was contrived for him, as there was for man, who fell by his temptation (Jude 6; Joh 8:44). From his peculiar connection with the earth and man, it has been conjectured that the exciting cause of his rebellion was God's declaration that human nature was to be raised into union with the Godhead; this was "the truth" concerning the person of the Son of God which "he abode not in"; it galled his pride that a lower race was to be raised to that which he had aspired to (1Ti 3:6). How exultingly he might say, when man fell through him, "God would raise manhood into union with Himself; I have brought it down below the beasts by sin!" At that very moment and spot he was told that the seed of the abhorred race, man, should bruise his head (1Jo 3:8). He was raised up for this, to show forth God's glory (Ex 9:16; Ro 9:17). In his unfallen state he may have been God's vicegerent over the earth and the animal kingdom before man: this will account for his assuming the form of a serpent (Ge 3:1). Man succeeded to that office (Ge 2:19, 20), but forfeited it by sin, whence Satan became "prince of this world"; JesusChrist supplants the usurper, and as "Son of man" regains the lost inheritance (Ps 8:4-8). The steps in Satan's overthrow are these: he is cast out, first, from heaven (Re 12:7-9) on earth; next, he is bound a thousand years (Re 20:2, 3); finally, he is cast into the lake of fire for ever (Re 20:10).
      the serpent's meat--(See on Isa 11:8).
      They shall not hurt nor destroy in all my holy mountain--(See on Isa 11:9).
