“"And of one Jesus," he says, "which was dead." He says naturally enough, "of one" Jesus, as being a man in office, and not caring for these things.”

“But had certain questions against him of their own superstition,.... Or religion; as about their law, which they said Paul had spoke against; and about their temple, which they pretended he had polluted; and about the resurrection of the dead, which he asserted, and some denied: and of one Jesus which was dead, whom Paul affirmed to be alive; for it seems more was said on each side, than is recorded by Luke: the Jews objected to him among other things, his belief in Jesus of Nazareth, whom they traduced as an impostor and deceiver; Paul on the other hand argued, that he was the true Messiah; and in proof of it, affirmed that though they had put him to death, he was risen from the dead, and so was declared to be the Son of God with power: Festus, it is very likely, had never heard of Jesus before, and therefore speaks of him in this manner; or if he had, he had entertained a contemptible opinion of him, as well as of the Jewish religion; and which he expresses, even in the presence of the king, who had outwardly at least embraced it.”

“Questions - of their own superstition - Περι της ιδιας δειδιδαιμονιας; Questions concerning their own religion. Superstition meant something as bad among the Romans as it does among us; and is it likely that Festus, only a procurator, should thus speak to Agrippa, a King, concerning his own religion? He could not have done so without offering the highest insult. The word δεισιδαιμονια must therefore simply mean religion - the national creed, and the national worship, as I have at large proved it to mean, in the observations at the end of Act 17:34. And of one Jesus, which was dead, etc. - In this way does this poor heathen speak of the death and resurrection of Christ! There are many who profess Christianity that do not appear to be much farther enlightened.”

“questions . . . of their own superstition--rather, "religion" (see on Act 17:22). It cannot be supposed that Festus would use the word in any discourteous sense in addressing his Jewish guest. one Jesus--"Thus speaks this miserable Festus of Him to whom every knee shall bow" [BENGEL]. whom Paul affirmed--"kept affirming." to be alive--showing that the resurrection of the Crucified One had been the burden, as usual, of Paul's pleading. The insignificance of the whole affair in the eyes of Festus is manifest.”
