This issue of Sh'ma focuses on the Book of Jonah, which is read in synagogues on the afternoon of Yom Kippur. Several essays explore the theme of teshuvah (repentance), including Jonah's complicated response to mercy and the search for justice. Jonah is often described as a reluctant prophet, and we include two essays that address prophecy, including one on how prophets can both distort and amplify the voices of democracy. Jonah's experience of fleeing and then finding himself in the belly of the fish raises questions about incarceration, and we include the voice of a woman in prison for decades grappling with the text, her guilt, and forgiveness. We also include pieces that explore minor themes of the book: What can it teach us about gratitude and loneliness, for instance? One educator recounts the story of Jonah through a child's imagination and another sees it through a teenager's angst; a scientist suggests how we might understand 'chance' in light of the story.
