And after certain days king Agrippa and Bernice came unto Caesarea to salute Festus.
And after certain days king Agrippa - great grandson of Herod the Great, and Drusilla's brother (see the note at Acts 24:24). On his father's awful death (Acts 12:23), being thought too young to succeed (only seventeen), Judea was attached to the province of Syria. Four years after, on the death of his uncle Herod, he was made king of the northern principalities of Chalcis, and afterward got Batanea, Iturea, Trachonitis, Abilene Galilee, and Perea, with the title of king. He died A.D. 100 AD, after rejoining 51 years.
And Bernice - his sister. She was married to her uncle Herod, king of Chalcis, on whose death she lived with her brother Agrippa-not without suspicion of incestuous sexual intercourse, which her subsequent licentious life tended to confirm.
Came unto Cesarea to salute Festus - to pay his respects to him on his accession to the procuratorship.
