1:17-21 There should be deliverance and holiness at Jerusalem, and the house of Jacob would again occupy their possessions. Much of this prophecy was fulfilled when the Jews returned to their own land. But the salvation and holiness of the gospel, its spread, and the conversion of the Gentiles, seem also to be intended, especially the restoration of Israel, the destruction of antichrist, and the prosperous state of the church, to which all the prophets bear witness. When Christ is come, and not till then, shall the kingdom be the Lord's in the full sense of the term. As none that exalt themselves against the Lord shall prosper, and all shall be brought down; so none that wait upon the Lord, and put their trust in him, shall ever be dismayed. Blessed be the Divine Saviour and Judge on Mount Zion! His word shall be a savour of life unto life unto numbers, while it judges and condemns obstinate unbelievers.
17. upon … Zion … deliverance—both in the literal sense and spiritual sense (Joe 2:32; Isa 46:13; 59:20; Ro 11:26). Maurer as the Margin explains it, "there shall be a remnant that shall escape." Compare Isa 37:32; to the deliverance from Sennacherib there described Grotius thinks Obadiah here refers. "Jerusalem shall not be taken, and many of the neighboring peoples also shall find deliverance there." Unlike Judah's heathen foes of whom no remnant shall escape (Ob 9, 16), a remnant of Jews shall escape when the rest of the nation has perished, and shall regain their ancient "possessions."
there shall be holiness—that is, Zion shall be sacrosanct or inviolable: no more violated by foreign invaders (Isa 42:1; Joe 3:17).
