The Return of the Unclean Spirit

‘When the unclean spirit has gone out of a person, it wanders through waterless regions looking for a resting-place, but it finds none. Then it says, “I will return to my house from which I came.” When it comes, it finds it empty, swept, and put in order. Then it goes and brings along seven other spirits more evil than itself, and they enter and live there; and the last state of that person is worse than the first. So will it be also with this evil generation.’
