Êxodo 8:2
For what reason do you puff yourself up with human pride? A man insulted you, and you swelled up and were angered. Rid yourself of the fleas that you may sleep. Find out who you are! For that you may know, brothers, that these things which would bother us were created to enable us to control our pride, [remember], God could have tamed the proud people of Pharaoh with bears, with lions or with snakes; he sent flies and frogs upon them that their pride might be tamed by the most ignoble of things. — TRACTATE ON THE GOSPEL OF JOHN 1.15
Êxodo 8:19
Here I see a difficulty occurring to one of limited knowledge [of Scripture], that is, why miracles are also done by magical arts, for the magicians of Pharaoh also made serpents and other similar things. But what is a much greater cause of wonder is how the power of the magicians, who could make serpents, utterly failed when it came to very small gnats. For the sciniphs, by which the proud people of Egypt were afflicted, are very small flies. And there certainly the magicians who failed, exclaimed, "This is the finger of God." We are thereby given to understand that not even the angels and the spirits of the air, who transgressed and were cast from that home of sublime and ethereal beauty into this most profound darkness, as into a prison peculiar to them, could do anything that they could by means of their magical arts, if the power had not been given to them from above. — THE TRINITY 3.7.12
Êxodo 8:19
Isn't the finger of God to be understood as being the Holy Spirit? Read the Gospel, and see that where one Evangelist has the Lord saying, "If I with the Spirit of God cast out demons," another says, "If I with the finger of God cast out demons." So if that law too was written by the finger of God, that is, by the Spirit of God, the Spirit by which Pharaoh's magicians were defeated, so they said, "This is the finger of God, … why can it not be said of it, "For the law of the Spirit of life in Christ Jesus has delivered you from the law of sin and death"? — SERMON 155.3
