Date: 3rd Century B.C.E.
The book of Jonah was included in "the Twelve," among the other prophetic books, because it was accepted as a prophetic book. Yet it is unlike all the other prophetic books in many and diverse ways. For one thing, the book of Jonah is a narrative, whereas the others are not, though they may include some narrative sections. Prophetic books tend to allocate a large share of their text to reports of divine announcements (or "oracles") and of prophetic addresses to a public other than the Lord or the prophet alone. This is clearly not the case in Jonah.
