Obadiah
One chapter long, a vision about Edom, the nation descended from Esau. It says Edom's pride in its high rocky strongholds will not save it: its allies will turn on it, its wise men and fighters will fall, and it will be plundered. The reason given is what Edom did on the day Jerusalem fell, when it stood by, gloated, looted, and handed over those who escaped.
