Matthew 12:33-42

Either make the tree good, and its fruit good; or make the tree corrupt, and its fruit corrupt: for the tree is known by its fruit. Ye offspring of vipers, how can ye, being evil, speak good things? for out of the abundance of the heart the mouth speaketh. The good man out of his good treasure bringeth forth good things: and the evil man out of his evil treasure bringeth forth evil things. And I say unto you, that every idle word that men shall speak, they shall give account thereof in the day of judgement. For by thy words thou shalt be justified, and by thy words thou shalt be condemned. Then certain of the scribes and Pharisees answered him, saying, Master, we would see a sign from thee. But he answered and said unto them, An evil and adulterous generation seeketh after a sign; and there shall no sign be given to it but the sign of Jonah the prophet: for as Jonah was three days and three nights in the belly of the whale; so shall the Son of man be three days and three nights in the heart of the earth. The men of Nineveh shall stand up in the judgement with this generation, and shall condemn it: for they repented at the preaching of Jonah; and behold, a greater than Jonah is here. The queen of the south shall rise up in the judgement with this generation, and shall condemn it: for she came from the ends of the earth to hear the wisdom of Solomon; and behold, a greater than Solomon is here.
