Jonah is the story of a prophet sent by God to Nineveh. Jonah is fearful of the call and tries to flee by sea to Tarshish. During the sea voyage he is thrown overboard by his fellow passengers and swallowed by a great fish sent by God. The prophet is saved and goes on to Nineveh to successfully convert the people of that city.

Jonah 3

3:4 And Jonah began to enter into the city a day's journey, and he cried, and said, Yet forty days, and Nineveh shall be overthrown.
