Luke 11:25

That is, to those who are of Israel, whom he saw possessing nothing divine in them, but desolate, and vacant for him to take up his abode there; and so it follows, And when he came, he findeth it swept and garnished.

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 goeth and taketh 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.

But he finds his house swept and garnished, that is, purified by the grace of baptism from the stain of sin, yet replenished with no diligence in good works.

After what had gone before, our Lord proceeds to show how it was that the Jewish people had sunk to these opinions concerning Christ, saying, When the unclean spirit is gone out of a man, &c. For that this example relates to the Jews, Matthew has explained when he says, Even so shall it be also unto this wicked generation. (Matt. 12:45.) For all the time that they were living in Egypt in the practice of the Egyptians, there dwelt in them an evil spirit, which was drawn out of them when they sacrificed the lamb as a type of Christ, and were sprinkled with its blood, and so escaped the destroyer. The last state also is worse than the first, according to the words of the Apostle, It were better not to have known the way of truth, than after they have known it to turn back from it. (2 Pet. 2:21.)
