But he, knowing their thoughts, said unto them,
Every kingdom divided against itself is brought to desolation; and a house divided against a house falls.

Cyril of Alexandria
AD 444
By the finger of God, he means the Holy Spirit. The Son is called the hand and arm of God the Father because he does all things by the Son, and the Son in a similar way works by the Spirit. Just as the finger is attached to the hand as something not foreign from it but belonging to it by nature, so also the Holy Spirit, by reason of his being equal in substance, is joined in oneness to the Son, although he proceeds from God the Father. The Son does every thing by the consubstantial Spirit. Here he purposely says that by the finger of God he casts out devils, speaking as a man. The Jews in the infirmity and folly of their mind would not have endured it if he said, “by my own Spirit I cast out devils.” Commentary on Luke, Homily
