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 not finding any, it says, “I will return to my house from which I came.” When it comes, it finds it swept and put in order. Then it goes and brings 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.’
