Of the author of this book, the shortest in the Old Testament, very little is known. It appears from his book that Obadiah ("servant of Jehovah") was a member of the southern kingdom, and it may be right to identify him with the man of the same name who lived under Jehoram, the son of Jehoshaphat. This would place him in the first half of the ninth century before Christ, an assumption which receives some further support by the fact that both Joe_2:32; Joe_3:2-3; and Jer_49:7-16 evidently refer to the prophecy of Obadiah.
The vision of Obadiah contains a severe arraignment of the Edomites for their traditional enmity against the people of God, on account of which he announces the divine judgment upon Idumea. After a further paragraph, in which the justice of this punishment upon Edom is established, the book closes with a promise of the restoration of Judah, a prediction which finds its complete fulfillment in the victories of the Church of Christ in the Messianic period. It is clear that the judgment upon Edom is intended as a type of the punishment upon all the enemies of the Lord, and that the fulfillment of the kingdom of the Messiah are the basic thoughts of the vision.
