John Chrysostom
Patristic
A.D. 347–407
“"And now, behold, the hand of the Lord is upon thee, and thou shalt be blind." It was the sign by which he was himself converted, and by this he would fain convert this man. As also that expression, "for a season," puts it not as an act of punishing, but as meant for his conversion: had it been for punishment, he would have made him lastingly blind, but now it is not so, but "for a season" (and this), that he may gain the proconsul. For, as he was prepossessed by the sorcery, it was well to teach him a lesson by this infliction (and the sorcerer also), in the same way as the magicians (in Egypt) were taught by the boils. "And immediately there fell on him a mist and a darkness: and he went about seeking some to lead him by the hand."”
