Matthew 12:39-41

Young's Literal Translation

³⁹ And he answering said to them, `A generation, evil and adulterous, doth seek a sign, and a sign shall not be given to it, except the sign of Jonah the prophet;

⁴⁰ for, as Jonah was in the belly of the fish three days and three nights, so shall the Son of Man be in the heart of the earth three days and three nights.

⁴¹ `Men of Nineveh shall stand up in the judgment with this generation, and shall condemn it, for they reformed at the proclamation of Jonah, and lo, a greater than Jonah here!
