“Then Festus, when he had conferred with the council, answered, Hast thou appealed unto Caesar? unto Caesar shalt thou go.”
King James Version (KJV)
25:12 The council - It was customary for a considerable number of persons of distinction to attend the Roman governors. These constituted a kind of council, with whom they frequently advised.
Ac 25:12 When he had conferred with the council. Festus' own counselors, men called "assessors", whose duty it was to advise the governor. He then announces the decision, I suppose, in the legal language used in such cases, "Hast thou appealed unto Caesar? unto Caesar thou shalt go".
