The Book of Job (Biblical Hebrew: אִיּוֹב, romanized: ʾĪyyōḇ), or simply Job, is a book found in the Ketuvim ("Writings") section of the Hebrew Bible and the first of the Poetic Books in the Old Testament of the Christian Bible.
The language of the Book of Job, combining post-Babylonian Hebrew and Aramaic influences, indicates it was composed during the Persian period (540–330 BCE), with the poet using Hebrew in a learned, literary manner. It addresses the problem of evil, providing a theodicy through the experiences of the eponymous protagonist. It is structured with a prose prologue and epilogue framing poetic dialogues and monologues, including three cycles of debates between Job and his friends, Job's lamentations, the Poem to Wisdom, Elihu's speeches, and God's two speeches from a whirlwind.
