But upon mount Zion shall be deliverance, and there shall be holiness; and the house of Jacob shall possess their possessions.
But upon mount Zion shall be deliverance - both in the literal sense and spiritual sense (repeated, with the fresh stamp of inspiration, from Joel 2:32; Isaiah 46:13; Isaiah 59:20; Romans 11:26). Maurer and Pusey, better, as margin, explain it, 'there shall be a remnant that shall escape;' 'an escaped remnant.' Compare Isaiah 37:32: to the deliverance from Sennacherib there described Grotius thinks Obadiah here refers, 'Jerusalem shall not be taken, and many of the neighbouring peoples also shall find deliverance there.' Unlike Judah's pagan foes, of whom no remnant shall escape (Obadiah 1:9; Obadiah 1:16), a remnant of Jews shall escape when the rest of the nation have perished, and shall "possess" or regain their ancient "possessions" - literally, 'shall inherit their inheritances.'
There shall be holiness - i:e., Zion shall be sacrosanct, or inviolable; no more violated by foreign invaders (Isaiah 52:1; Joel 3:17, "Then shall Jerusalem be" holiness (margin), "and there shall no strangers pass through her anymore;" or 'IT,' i:e., the escaped remnant, 'shall be holinesss').
