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

1:20 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.
