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

1:18 And the house of Jacob shall be a fire, and the house of Joseph a flame, and the house of Esau for stubble, and they shall kindle in them, and devour them; and there shall not be any remaining of the house of Esau; for the LORD hath spoken it.
