John Wesley on Acts 26:3

Who art accurately acquainted - Which Festus was not; with the customs - In practical matters; and questions - In speculative. This word Festus had used in the absence of Paul, Acts 25:19, who, by the Divine leading, repeats and explains it. Agrippa had had peculiar advantages for an accurate knowledge of the Jewish customs and questions, from his education under his father Herod, and his long abode at Jerusalem. Nothing can be imagined more suitable or more graceful, than this whole discourse of Paul before Agrippa; in which the seriousness of the Christian, the boldness of the apostle, and the politeness of the gentleman and the scholar, appear in a most beautiful contrast, or rather a most happy union.
