Summary: Jonah got swallowed by a great fish for three days and nights because he tried very hard to not do what God had asked him to do. Then, Jonah got angry enough to claim to want to die when the people of Nineveh repented and God showed mercy and loving kindness. God used a vine to try to teach Jonah about compassion.
