Then the deputy, when he saw what was done, believed, being astonished at the doctrine of the Lord.
Read Chapter 13
John Chrysostom
AD 407
he saw that these things were not mere words, nor trickery. Mark how he loved to receive instruction from his teachers, though he was in a station of so high authority. And (Paul) said not to the sorcerer, Will you not cease to pervert the proconsul? What may be the reason of John's going back from them? For John, it says, departing from them returned to Jerusalem
But observe, how they do not linger there, as (they might have been tempted to do) now that the proconsul was a believer, nor are enervated by being courted and honored, but immediately keep on with their work, and set out for the country on the opposite coast. Now when Paul and his company loosed from Paphos, they came to Perga in Pamphylia; and John departing from them returned to Jerusalem. But when they departed from Perga, they came to Antioch in Pisidia, and went into the synagogue on the sabbath day, and sat down.
