Obadiah 1:17

But upon Mount Zion shall be deliverance - Here is a promise of the return from the Babylonish captivity. They shall come to Zion, and there they shall find safety; and it is remarkable that after their return they were greatly befriended by the Persian kings, and by Alexander the Great and his successors; so that, whilst they ravaged the neighboring nations, the Jews were unmolested. See Calmet.

And there shall be holiness - They shall return to God, separate themselves from their idols, and become a better people than they were when God permitted them to be carried into captivity.

The house of Jacob shall possess - They were restored to their former possessions. But this may refer also to their future restoration under the Gospel, when they shall be truly converted, and become holiness to the Lord; for salvation and holiness shall be the characteristics of Zion - the Christian Church, for ever.

But (And) upon (in) Mount Zion, shall be deliverance, or, an escaped remnant, and there (and it) shall be holiness - The sifting times of the Church are the triumph of the world; the judgment of the world is the restoration of the Church. In the triumph of the world, the lot was cast on Jerusalem, her sons were carried captive and slain, her holy places were desecrated. On the destruction of the nations, Mount Zion rises in calm majesty, as before; "a remnant" is replaced there, after its sifting; it is again "holiness;" not holy only, but a channel of holiness; "and the house of Jacob shall possess their possessions (literally inherit their inheritances)"; either their own former possessions, receiving and "inheriting" from the enemy, what they had lost; or the "inheritances" of the nations. For the whole world is the inheritance of the Church, as Jesus said to the apostles, sons of Zion Matthew 28:19, "Go ye and teach all nations, baptizing them in the Name of the Father and of the Son and of the Holy Spirit." and Mark 16:15, "Go ye into all the world and preach the Gospel to every creature." Holiness is its title-deeds to the inheritance of the world, that holiness, which was in the "upper chamber" in "Mount Zion," the presence of God the Holy Spirit, issuing in holy teaching, holy Scriptures, holy institutions, holy sacraments, holy lives.

1:17 Zion - Literally this refers to the Jews: typically to the gospel - church. Deliverance - A remnant that shall be delivered by Cyrus, a type of Israel's redemption by Christ.Holiness - The temple, the city, the people returned from captivity shall be holy to the Lord. Their possessions - Their own ancient possessions.
