Obidiah is addressed to the kingdom of Edom (Esau) (v1). Because of its treatment of Israel, Edom as a nation “shalt be cut off for ever” (v10). (Yet we read in Amos 9:12 that believers in Edom will not utterly perish.) The day of the LORD will come as a punishment to Edom (v15).
17 But upon mount Zion shall be deliverance, and there shall be holiness; and the house of Jacob shall possess their possessions.
20 And the captivity of this host of the children of Israel shall possess that of the Canaanites, even unto Zarephath; and the captivity of Jerusalem, which is in Sepharad, shall possess the cities of the south.
21 And saviours shall come up on mount Zion to judge the mount of Esau; and the kingdom shall be the LORD's.
Like the other prophets, Obadiah ends with an unconditional promise that God would restore Israel as a nation (v17, 20, 21).
