Obadiah

To announce God's judgment on Edom for its betrayal of Israel during Jerusalem's greatest hour of need, and to promise that God will vindicate his people.

The shortest book in the Old Testament pronounces judgment on Edom for standing by while Jerusalem fell, gloating over Judah's disaster, and handing over survivors — concluding with the promise that Zion will be restored and the kingdom will be the Lord's.

Obadiah's single chapter demonstrates that God's justice extends to every act of brotherly betrayal and every expression of pride — and that history's final word belongs to God's kingdom.
