It shall not be quenched night nor day; the smoke thereof shall go up for ever: from generation to generation it shall lie waste; none shall pass through it for ever and ever.
It - the "burning pitch" (Isaiah 34:9).
Smoke ... for ever - (Revelation 14:11; Revelation 18:18; Revelation 19:3).
From generation to generation - (Malachi 1:4.)
None shall pass through. Edom's original offence was, it would not let Israel pass through their land in peace to Canaan: God "recompenses" them in kind; no traveler shall pass through Edom. Volney, the infidel, was forced to confirm the truth of this prophecy: 'From the reports of the Arabs, southeast of the Dead Sea, within three days' journey, are upwards of thirty ruined towns, absolutely deserted.'
