Acts 4:5

5, 6. The prisoners having been arrested late in the afternoon, all further proceedings were adjourned till the next day, and Peter and John had the quiet of a night in prison for reflection and mutual encouragement ere they were brought to trial. (5) " And it came to pass on the morrow, that their rulers and elders and scribes, (6) and Annas the high priest, and Caiaphas, and John and Alexander, and as many as were of the kindred of the high priest, were gathered together in Jerusalem. " This assembly was the great Jewish Sanhedrim, and the parties here named are the different officials who constituted that tribunal. Who John and Alexander were is not now known. Annas and Caiaphas are historical characters, conspicuous in the history of the trial of Jesus, and also prominent on the pages of Josephus. Between the latter and Luke there is an apparent discrepancy, in reference to their official position at this time, Luke calling Annas the high priest, and Josephus attributing that dignity to Caiaphas. According to Josephus, Valerius Gratus, the immediate predecessor of Pontius Pilate, had removed Annas from the high priesthood, and after having appointed and removed three others, one of them, Eleazar, the son of Annas, finally left Caiaphas in office, when he was superseded by Pilate. The Apostle John informs us that Caiaphas was son-in-law to Annas. According to the law of Moses the high priest held office during life; hence, in deposing Annas, the Roman governor violated the Jewish Law, and the act was religiously null and void. Annas was still high priest by right, and for this reason is so styled here by Luke. The Jews, also, recognized his right, by taking Jesus before him for trial, though he, not daring to claim the office, sent them to Caiaphas. In his former narrative, Luke also mentions them both as being high priests at the same time. This is best explained by the fact that one was rightfully entitled to the office, and the other was exercising it by illegal appointment.

The "kindred of the high priest" embraced not only the chief members of his immediate family, but also some of the deposed high priests, who were all, in great probability, connected with the one high priestly family, and thereby entitled to seats in the Sanhedrim.
