John Chrysostom, on Acts 8:9

“There was therefore great joy in that city. Now there was a certain man named Simon, who before had been a magician in that city, seducing the people of Samaria, giving out that he was some great one:”

“"But there was a certain man, called Simon, which before time in the same city used sorcery, and bewitched the people of Samaria." Observe another trial, this affair of Simon. "Giving out," it says, "that he was himself some great one. To whom they all gave heed, from the least to the greatest, saying, This man is the great power of God. And to him they had regard, because that of long time he had bewitched them with sorceries." "Of a long time" was the malady, but this man (Philip) brought them deliverance.”
