Matthew 12:39-41

12:39 But he answered them, “An evil and adulterous generation asks for a sign, but no sign will be given to it except the sign of the prophet Jonah. 12:40 For just as Jonah was in the belly of the huge fish for three days and three nights, so the Son of Man will be in the heart of the earth for three days and three nights. 12:41 The people of Nineveh will stand up at the judgment with this generation and condemn it, because they repented when Jonah preached to them – and now, something greater than Jonah is here!
