When the unclean spirit is gone out of a man, he walks through dry places, seeking rest; and finding none, he says, I will return unto my house from which I came out.
All Commentaries on Luke 11:24 Go To Luke 11

The comparison then is between one man and the whole Jewish people, from whom through the Law the unclean spirit had been cast out. But because in the Gentiles, whose hearts were first barren, but afterwards arcs in baptism moistened with the dew of the Spirit, the devil could find no rest because of their faith in Christ, (for to the unclean spirits Christ is a flaming fire,) he then returned to the Jewish people. Hence it follows, And finding none, he said, I will return to my house whence I came.
For Israel being adorned with a mere outward and superficial beauty, remains inwardly the more polluted in her heart. For she never quenched or allayed her fires in the water of the sacred fountain, and rightly did the unclean spirit return to her, bringing with him seven other spirits more wicked than himself. Hence it follows, And he goes and takes with him seven other spirits more wicked than himself, and they enter in and dwell there. Seeing that in truth she has sacrilegiously profaned the seven weeks of the Law, (i.e. from Easter to Pentecost,) and the mystery of the eighth day. Therefore as upon us is multiplied the seven-fold gifts of the Spirit, so upon them falls the whole accumulated attack of the unclean spirits. For the number seven is frequently taken to mean the whole.
