Adam Clarke on Acts 19:31

Certain of the chief of Asia - Τινες των Ασιαρχων; Some of the Asiarchs. The Asiarchs were those to whom the care and regulation of the public games were intrusted: they were a sort of high priests, and were always persons of considerable riches and influence. These could not have been Christians; but they were what the sacred text states them to have been, αυτῳ φιλοι, his friends; and foreseeing that Paul would be exposed to great danger if he went into the theater, amidst such a tumultuous assembly, they sent a message to him, entreating him not to go into danger so apparent. Query: Did he not go, and fight with these wild beasts at Ephesus? 1Cor 15:32.
