Matthew 12:38-42 - The Sign Of Jonah
38 Then answered certain of the scribes and of the Pharisees saying, "Master, we would fain see a sign of thee."
39 He answered them saying, "The evil and adulterous generation seeketh a sign; but there shall no sign be given to them, but the sign of the prophet Jonah: 40 For as Jonah was three days and three nights in the whale's belly; so shall the son of man be three days and three nights in the heart of the earth. 41 The men of Nineveh shall rise at the day of judgment with this nation, and condemn them: for they amended at the preaching of Jonah. And behold, a greater than Jonah is here. 42 The queen of the south shall rise at the day of judgment with this generation, and shall condemn them: for she came from the utmost parts of the world, to hear the wisdom of Solomon. And behold, a greater than Solomon is here.
29 When the people were gathered thick together, he began to say, This is an evil nation. They seek a sign, and there shall no sign be given them, but the sign of Jonah the prophet. 30 For as Jonah was a sign to the Ninevites, so shall the son of man be to this nation. 31 The queen of the south shall rise at the judgment, with the men of this generation, and condemn them. For she came from the end of the world, to hear the wisdom of Solomon: and behold a greater than Solomon is here. 32 The men of Nineveh shall rise at the judgment, with this generation, and shall condemn them: for they repented at the preaching of Jonah: And behold, a greater than Jonah is here.
