37 For each of you by his words shall be justified, or by his words shall be condemned."

40 For just as Jonah was three days in the sea-monster's belly, so will the Son of Man be three days in the heart of the earth.
41 There will stand up men of Nineveh at the Judgement together with the present generation, and will condemn it; because they repented at the preaching of Jonah, and mark! there is One greater than Jonah here.
