The Unclean Spirit

Matthew 12:43-45
[12:43] 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.

Luke 11:24-26
[11:24] When the unclean spirit is gone out of a man, he walketh through dry places, seeking rest; and finding none, he saith, I will return unto my house whence I came out. [25] And when he cometh, he findeth it swept and garnished. [26] Then goeth he, and taketh to him 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.
