Matt 12:43 - 45.
43 And when an unclean spirit is gone out of a man he walketh through dry places seeking rest, and findeth none. 44 Then he saith: I will return into my house from whence I came out. And coming he findeth it empty, swept, and garnished. 45 Then he goeth, and taketh with him seven other spirits more wicked than himself, and they enter in and dwell there: and the last state of that man is made worse than the first. So shall it be also to this wicked generation.
