Charles Ellicott Commentary Acts 25:14

"And as they tarried there many days, Festus laid Paul`s case before the King, saying, There is a certain man left a prisoner by Felix;" — Acts 25:14 (ASV)

Festus declared Paul’s cause to the king.—The matter seems to have come up, as it were, in the course of conversation. Festus probably thought that Agrippa, who knew all about the Jews and their religion, could throw some light on the peculiar position of his prisoner, who, though a Jew, and professing the utmost reverence for the Law and the Temple, was yet accused and denounced by his compatriots.
