17 But in Mount Zion some will be kept safe, and it will be holy; and the children of Jacob will take their heritage. 18 And the children of Jacob will be a fire and those of Joseph a flame, and the children of Esau dry stems of grass, burned up by them till all is gone: and there will be no people living in Esau; for the Lord has said it. 19 And they will take the South, and the lowland, and the country of Ephraim, and Gilead, as their heritage. 20 And those of the children of Israel who were the first to be taken away as prisoners, will have their heritage among the Canaanites as far as Zarephath; and those who were taken away from Jerusalem, who are in Sepharad, will have the towns of the South. 21 And those who have been kept safe will come up from Mount Zion to be judges of the mountain of Esau; and the kingdom will be the Lord's.

Commentary on Obadiah 1:17-21

(Read Obadiah 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.
