At that time, the scribes and Pharisees came to Jesus 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 shall be given to it except the sign of the prophet Jonah. For as Jonah was three days and three nights in the belly of the whale, so will the Son of man be three days and three nights in the heart of the earth. The men of Nineveh will arise 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 arise 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 man, he passes through waterless places seeking rest, but he finds none. Then he says, 'I will return to my house from which I came.' And when he comes he finds it empty, swept, and put in order. Then he goes and brings with him seven other spirits more evil than himself, and they enter and dwell there; and the last state of that man becomes worse than the first. So shall it be also with this evil generation."
