Obadiah, containing only one chapter, is the shortest book in the Old Testament. In it is given a prophetic interpretation of a great calamity that has already occurred in Edom and a prediction of a universal judgment.

Obadiah 1

1:11 In the day that thou stoodest on the other side, in the day that the strangers carried away captive his forces, and foreigners entered into his gates, and cast lots upon Jerusalem, even thou wast as one of them.
