Matthew 12
38 Ref Then certain of the scribes and Pharisees answered, "Teacher, we want to see a sign from you."
39 Ref But he answered them, "An evil and adulterous generation seeks after a sign, but no sign will be given it but the sign of Jonah the prophet.
40 Ref 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 Ref The men of Nineveh will stand up in the judgment with this generation, and will condemn it, for they repented at the preaching of Jonah; and behold, someone greater than Jonah is here.
