Matthew 12:38-42 - The Sign Of Jonah
38 Then some of the scribes and Pharisees said to him, "Teacher, we want to see a sign from you."
39 But he answered them, "An evil and adulterous generation seeks for a sign; but no sign will 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 great fish, so the Son of Man will be three days and three nights in the heart of the earth. 41 The men of Nineveh will stand up at the judgment with this generation and condemn it; for they repented at the preaching of Jonah, and now one greater than Jonah is here. 42 The queen of the South will rise 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.
29 When the crowds were increasing, he began to say, "This is an evil generation. It seeks a sign, but no sign will be given to it except the sign of Jonah. 30 For as Jonah became a sign to the Ninevites, so also the Son of Man will be to this generation. 31 The queen of the South will rise at the judgment with the men of this generation and condemn them; for she came from the ends of the earth to hear the wisdom of Solomon, and behold, something greater than Solomon is here. 32 The men of Nineveh will stand up at the judgment with this generation and condemn it; for they repented at the preaching of Jonah, and behold, one greater than Jonah is here.
