Jonah was a man whom God asked to go to Nineveh, but Jonah ran away and sailed on a ship instead. A big storm came, and Jonah ended up in the sea, where a huge fish swallowed him. Jonah prayed inside the fish for three days, and God made the fish spit him out. Jonah then listened to God, went to Nineveh, and the people decided to change their ways.
