Matthew 12:43-45 KJV:
43 – When the 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 when he is come, he findeth it empty, swept, and garnished.
45 – Then goeth he, and taketh with himself seven other spirits more wicked than himself, and they enter in and dwell there: and the last state of that man is worse than the first. Even so shall it be also unto this wicked generation.
