Matthew 12:38-41

Then some of the Pharisees and teachers of the law answered Jesus, saying, “Teacher, we want to see you work a miracle as a sign.” Jesus answered, “Evil and sinful people are the ones who want to see a miracle for a sign. But no sign will be given to them, except the sign of the prophet Jonah. Jonah was in the stomach of the big fish for three days and three nights. In the same way, the Son of Man will be in the grave three days and three nights. On the Judgment Day the people from Nineveh will stand up with you people who live now, and they will show that you are guilty. When Jonah preached to them, they were sorry and changed their lives. And I tell you that someone greater than Jonah is here.
