Then he goes, and takes with himself seven other spirits more evil than he is, and they enter in and dwell there. The last state of that man becomes worse than the first. Even so will it be also to this evil generation."

An evil and adulterous generation seeks after a sign, and there will be no sign given to it, except the sign of the prophet Jonah." He left them, and departed.
