Who Obadiah was and when he lived is a topic of debate. There were many Obadiahs in the time of the Tanakh. But it is clear to whom Obadiah is prophesying. The content is rough, the tone is strong, the vision is ominous. Obadiah is a sad book because in it we see just how far brothers can stray from each another and how their respective families can evolve into violent enemies even when one side is at its complete lowest.
