This pericope (section of text), as the former one, also has a framing phrase: "the mountain of Esau"(vv. 19, 21). This mountain, of course, contrasts with the Lord's holy mountain, Zion (vv. 16-17).
vv. 19-20 Obadiah predicted that Jews living in various parts of Israel would possess parts of the Promised Land that other nations formerly occupied. These parts included Mt. Seir (Edom), Philistia, territories to the north of Judah including Ephraim and Samaria (the Northern Kingdom), and Transjordan (Gilead). Formerly exiled Israelites living to the north near Zarephath (in modern Lebanon) and in Sepharad (perhaps Sardis in modern Turkey or a territory in Media or Spain41) would return and occupy the southern portions of the land, the Negev. Israel would again conquer the land, but this time she would subdue it completely and occupy all the territory God had promised Abraham (cf. Gen. 13:14-17; 26:2-5; 28:13-15; Deut. 1:7).
v. 21 In summary, those who would deliver the Jews to their divinely intended destiny would ascend Mt. Zion and would judge Mt. Seir. Edom would not prevail over Israel, but Yahweh would prove to be sovereign (cf. v. 1). His kingdom would extend over the whole Promised Land, even the part that Israel's enemies formerly occupied and the people who formerly opposed them. The conquest of the land that Joshua began but did not finish will be complete then. Thus Obadiah's prophecy, this tale of two mountains, ends on a climax with Yahweh's kingdom dominating all the nations and with Yahweh as King of Kings and Lord of Lords.
"None of the prophets has a more exalted close than this. . . . No man-ruled empire nor any nation of this world will endure forever. All will one day be merged into that eternal kingdom over which the Lord Jesus Christ will reign in solitary glory."42
Amillennial interpreters interpret New Testament references to Israel as references to the church. They see the fulfillment of Obadiah's prophecy not in the restoration of Old Testament Israel to future sovereignty in the Promised Land but in the final victory of the church over all her enemies.43Premillennialists reject this "replacement theology"(the church replaces Israel in God's program) because we believe when God said "Israel"He meant Israel. It is incorrect, we believe, to conclude that because Christians are the spiritual seed of Abraham the church is the spiritual seed of Israel.
