After Felix dies, Porcius Festus takes over. He tries to keep Paul in prison like Felix had, but Paul appeals to Caesar. Now Festus has no choice but to send him to caesar.
Then Agrippa and Bernice get involved, but will make little change for Paul or for Festus. This Agrippa is king (Herod’s family) and surely has knowledge of all that has happened since Jesus died and rose from the grave (which has now been over 25 years time).
