This chapter sets the stage for Paul's witness to King Agrippa. Here he is accused before the new governor Festus and then presented before Agrippa. Paul appeals to Caesar and his journey Rome will follow (chapter 27-28).
"The narrator's characterization of the Roman governors contributes to a portrait of Paul as one caught in a web of self-interested maneuvers by people who vie for support within the political jungle. However, Paul is not just a helpless victim. As opportunity comes, he continues to bear witness to his Lord. Although Paul continues to be denied justice and freedom, the saving purpose of God still has use for this resourceful and faithful prisoner." (Pillar New Testament Commentary Collection)
