Matthew 12:38-42 Revised Standard Version (RSV)
The Sign of Jonah
38 Then some of the scribes and Pharisees said to him, “Teacher, we wish to see a sign from you.” 39 But he answered them, “An evil and adulterous generation seeks for a sign; but no sign shall be given to it except the sign of the prophet Jonah. 40 For as Jonah was three days and three nights in the belly of the whale, so will the Son of man be three days and three nights in the heart of the earth. 41 The men of Nin′eveh will arise at the judgment with this generation and condemn it; for they repented at the preaching of Jonah, and behold, something greater than Jonah is here. 42 The queen of the South will arise at the judgment with this generation and condemn it; for she came from the ends of the earth to hear the wisdom of Solomon, and behold, something greater than Solomon is here.
