17 "But Jerusalem will become a refuge for those who escape; it will be a holy place. And the people of Israel will come back to reclaim their inheritance. 18 The people of Israel will be a raging fire, and Edom a field of dry stubble. The descendants of Joseph will be a flame roaring across the field, devouring everything. There will be no survivors in Edom. I, the Lord, have spoken! 19 "Then my people living in the Negev will occupy the mountains of Edom. Those living in the foothills of Judah will possess the Philistine plains and take over the fields of Ephraim and Samaria. And the people of Benjamin will occupy the land of Gilead. 20 The exiles of Israel will return to their land and occupy the Phoenician coast as far north as Zarephath. The captives from Jerusalem exiled in the north will return home and resettle the towns of the Negev. 21 Those who have been rescued will go up to Mount Zion in Jerusalem to rule over the mountains of Edom. And the Lord himself will be king!"

Matthew Henry's Commentary on Obadiah 1:17-21

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.
