Obadiah is a biblical prophet. The authorship of the Book of Obadiah is traditionally attributed to the prophet Obadiah.
Most scholars date the Book of Obadiah to shortly after the fall of Jerusalem in 587 BC. Other scholars hold that the book was shaped by the conflicts between Yehud and the Edomites in the fifth and fourth centuries BCE and evolved through a process of redaction.
The composition date is disputed and difficult to determine due to the lack of information regarding the prophet Obadiah. However, because Obadiah wrote about Edom, there are two generally accepted dates. The first is 853–841 BC, when Jerusalem was invaded by Philistines and Arabs during the reign of Jehoram of Judah. This earlier period would place Obadiah as a contemporary of the prophet Elijah. Jewish traditions favor the earlier date because the Jewish Talmud identifies Obadiah as an Edomite himself, and a descendant of Eliphaz the Temanite, the first of the friends of Job to speak with him about his tribulations.
