The Book of Jonah is read in the synagogue on the afternoon of Yom Kippur, the holiest day in the Jewish calendar, the sacred Day of Atonement. Why, of all books in the Bible, this book this most holy day?
The answer is clear. The major themes of the book are singularly appropriate to the occasion—sin and divine judgment, repentance and divine forgiveness.
What is remarkable is that the work is not at all about Israel. The sinners and penitents and the sympathetic characters are all pagans, while the anti-hero, the one who misunderstands the true nature of the one God, is none other than the Hebrew prophet. He is the one whom God must teach a lesson in compassion.
