Luke 11:23-28
English Standard Version
24"When the unclean spirit has gone out of a person, it passes through waterless places seeking rest, and finding none it says, ‘I will return to my house from which I came.’
25And when it comes, it finds the house swept and put in order.
26Then it goes and brings seven other spirits more evil than itself, and they enter and dwell there. And the last state of that person is worse than the first."
