The fifth book in the Twelve Minor Prophets. The book has four chapters, which describe Jonah's mission to Nineveh and the calamities that befell him there. It seems that Jonah the prophet lived in the time of Rehoboam II, king of Israel, in the eighth century BCE. He is mentioned in II Kings (15:25) as the prophet who foretold that Rehoboam would extend the borders of the Kingdom of Israel. The Book of Jonah is read as the Haftarah in the Minhah service of Yom Kippur in order to demonstrate the universal power of repentance and the vastness of God's mercy.
