Matthew 12:43-45

But when the unclean spirit has gone out of a man, it roams through dry [arid] places in search of rest, but it does not find any. Then it says, I will go back to my house from which I came out. And when it arrives, it finds the place unoccupied, swept, put in order, and decorated. Then it goes and brings with it seven other spirits more wicked than itself, and they go in and make their home there. And the last condition of that man becomes worse than the first. So also shall it be with this wicked generation.
