The Book of Obadiah is an oracle concerning the divine judgment of Edom and the restoration of Israel. The text consists of a single chapter, divided into 21 verses, making it the shortest book in the Hebrew Bible. In Judaism and Christianity, its authorship is attributed to Obadiah, a prophet who lived in the Assyrian Period.
In Judaism, Obadiah is one of the Twelve Minor Prophets in the final section of Nevi'im, the second main division of the Tanakh. In Christianity, the Book of Obadiah is classified as a minor prophet of the Old Testament, due to its short length.
