This concept is developed in the Book of Jonah: Jonah, the son of truth (the name of his father "Amitai" in Hebrew means truth), refuses to ask the people of Nineveh to repent. When forced to go, his call is heard loud and clear.
Mainstream Biblical historians generally regard the Book of Jonah as fictional and at least partially satirical, but the character of Jonah may have been based on a historical prophet.
In Judaism, the story of Jonah represents the teaching of teshuva, which is the ability to repent and be forgiven by God.
In the Gospel of Matthew, Jesus makes a reference to Jonah when he is asked for a sign by some of the scribes and the Pharisees.
Jesus says that the sign will be the sign of Jonah: Jonah's restoration after three days inside the great fish prefigures His own resurrection.
God causes a plant (in Hebrew a kikayon) to grow over Jonah's shelter to give him some shade from the sun.
Later, God causes a worm to bite the plant's root and it withers.
In the New Testament, Jesus calls himself "greater than Jonah" and promises the Pharisees "the sign of Jonah", which is his resurrection.
Early Christian interpreters viewed Jonah as a type for Jesus.
Jonah is regarded as a saint by a number of Christian denominations.
