Acts 26:27 - Ellicott's Commentary On The Whole Bible

Believest thou the prophets? — The appeal to Agrippa’s knowledge was followed by the assumption of his accepting the ground on which St. Paul invited discussion. He might, of course, dispute St. Paul’s interpretation of prophecy, but he could not, as a Jew, in the presence of other Jews, speak of the Law and the Prophets as Festus had spoken of St. Paul’s “learning,” and so the way might have been opened to that argument from prophecy which, when the Apostle was reasoning with his own countrymen, was (as in Acts 13:16-41; Acts 18:2-3) his favourite method of producing conviction.
