But if I with the finger of God cast out devils, no doubt the kingdom of God is come upon you. Here Jesus points to a fact well known and thoroughly established. There was no question here; the most obstinate cases of possession had yielded to that "finger" be spoke of here; the fiercest of the, alas! (then) great company of the insane, at the bidding of that quiet, humble Rabbi, for ever shook off the spirit of madness, in whatever form of terrible possession it had been dwelling in his body. There was no question here; the only point raised by his enemies how had that quiet Rabbi done these strange, mighty works—Jesus had answered; and now draws a picture of one of these acts of his. The "finger of God" in St. Matthew, where the same or a similar discourse is related, is called the "Spirit of God." The expression is strange, but is one not unusual in ancient Hebrew phraseology. So the Egyptian magicians said to Pharaoh, "This is the finger of God" (Exodus 8:19). The ten commandments are described as written on the two tables of stone with the "finger of God." "You have seen by what power the devils obey me; yea, the kingdom of God, for which you are waiting and looking, lo, it is come upon you."
When a strong man armed keepeth his palace, his goods are in peace: but when a stronger than he shall come upon him, and overcome him, he taketh from him all his armor wherein he trusted, and divideth his spoils. The exegesis is easy here. The strong man is the devil; his palace is the world; his goods especially here the poor possessed; the stronger than he is Jesus himself, who, as he paints this feature in the picture, is thinking of the scenes of the temptation, when in good earnest he overcame his ghostly adversary, then he took from him all his armor wherein he trusted, and now he, the Conqueror, divideth his spoils, among which are these unhappy possessed ones now being rescued from the power of their tormentor.
