King Agrippa II, great grandson of Herod the Butcher King, hears about the new governor and comes to pay his respects. He brings his sister Bernice, who is now living with him after becoming a widow. Rumors have been circulating that the relationship between Agrippa and Bernice has become more than just a sibling relationship, but they have not admitted to anything. Festus is curious, but knows better than to show it. He is honored by their visit, since most kings simply send a letter of greeting, and he is receiving a royal visit instead. The governor’s soldiers show King Agrippa’s entourage to the guest suites where he and his sister will stay during their visit and prepare the space to the king’s liking. Agrippa and Bernice stay for several weeks, acquainting themselves with Festus and enjoying nightly entertainment. One day, Festus tells the king about Paul, hoping that Agrippa might be able to shed some light on the case.
