“Either make the tree good and its fruit good, or make the tree bad and its fruit bad, for the tree is known by its fruit.  You brood of vipers! How can you speak good, when you are evil? For out of the abundance of the heart the mouth speaks.  The good person out of his good treasure brings forth good, and the evil person out of his evil treasure brings forth evil.  I tell you, on the day of judgment people will give account for every careless word they speak,  for by your words you will be justified, and by your words you will be condemned.”
 Then some of the scribes and Pharisees answered him, saying, “Teacher, we wish to see a sign from you.”  But he answered them, “An evil and adulterous generation seeks for a sign, but no sign will be given to it except the sign of the prophet Jonah.  For just as Jonah was three days and three nights in the belly of the great fish, so will the Son of Man be three days and three nights in the heart of the earth.  The men of Nineveh will rise up at the judgment with this generation and condemn it, for they repented at the preaching of Jonah, and behold, something greater than Jonah is here.  The queen of the South will rise up at the judgment with this generation and condemn it, for she came from the ends of the earth to hear the wisdom of Solomon, and behold, something greater than Solomon is here.
 “When the unclean spirit has gone out of a person, it passes through waterless places seeking rest, but finds none.  Then it says, ‘I will return to my house from which I came.’ And when it comes, it finds the house empty, swept, and put in order.  Then it goes and brings with it seven other spirits more evil than itself, and they enter and dwell there, and the last state of that person is worse than the first. So also will it be with this evil generation.”
