Acts 23:2

2. the high priest ... commanded ... to smite him on the mouth--a method of silencing a speaker common in the East to this day [Hacket]. But for a judge thus to treat a prisoner on his "trial," for merely prefacing his defense by a protestation of his integrity, was infamous.

Verse 2. And the High Priest Ananias. This Ananias was, doubtless, the son of Nebedinus, (Jos. Ant. xx. chap. v.  3,) who was high priest when Quadratus, who preceded Felix, was president of Syria. He was sent bound to Rome by Quadratus, at the same time with Ananias, the prefect of the temple, that they might give an account of their conduct to Claudius Caesar. Josephus, Ant. b. xx. chap. vi. & 2. But in consequence of the intercession of Agrippa the Younger, they were dismissed, and returned to Jerusalem. Ananias, however, was not restored to the office of high priest; for, when Felix was governor of Judea, this office was filled by Jonathan, who succeeded Ananias. Josephus, Ant. b. xx. chap. x. Jonathan was slain in the temple itself, by the instigation of Felix, by assassins who had been hired for the purpose. This murder is thus described by Josephus, (Ant. b. xx. chap. viii.  5 :)

"Felix bore an ill-will to Jonathan, the high priest, because he
frequently gave him admonitions about governing the Jewish
affairs better than he did, lest complaints should be made
against him, since he had procured of Caesar the appointment
of Felix as procurator of Judea. Accordingly, Felix contrived
a method by which he might get rid of Jonathan, whose
admonitions had become troublesome to him. Felix persuaded one
of Jonathan's most faithful friends, of the name Doras,
to bring the robbers upon him, and to put him to death."

This was done in Jerusalem. The robbers came into the city as if to worship God, and with daggers, which they had concealed under their garments, they put him to death. After the death of Jonathan, the office of high priest remained vacant, until king Agrippa appointed Ismael, the son of Fabi, to the office. Josephus, Ant. b. xx. chap. viii.  8. It was during this interval, while the office of high priest was vacant, that the events which are here recorded took place. Ananias was then at Jerusalem; and as the office of high priest was vacant, and as he was the last person who had borne the office, it was natural that he should discharge, probably by common consent, its duties, so far at least as to preside in the sanhedrim. Of these facts Paul would be doubtless apprized; and hence what he said Acts 23:5 was strictly true, and is one of the evidences that Luke's history accords precisely with the peculiar circumstances which then existed. When Luke here calls Ananias "the high priest," he evidently intends not to affirm that he was actually such; but to use the word as the Jews did, as applicable to one who had been ill that office, and who, on that occasion, when the office was vacant, performed its duties.

To smite him on the mouth. To stop him from speaking; to express their indignation at what he had said. The anger of Ananias was excited, because Paul affirmed that all that he had done had been with a good conscience. Their feelings had been excited to the utmost; they regarded him as certainly guilty; they deemed him to be an apostate; and they could not bear it that he, with such coolness and firmness, declared that all his conduct had been under the direction of a good conscience. The injustice of the command of Ananias is apparent to all. A similar instance of violence occurred on the trial of the Saviour, Jn 18:22.

Verse 2 The high priest, Ananias - There was a high priest of this name, who was sent a prisoner to Rome by Quadratus, governor of Syria, to give an account of the part he took in the quarrel between the Jews and the Samaritans; see Joseph. Antiq. lib. xx. cap. 6, s. 8; but whether he ever returned again to Jerusalem, says Dr. Lightfoot, is uncertain; still more uncertain whether he was ever restored to the office of high priest; and most uncertain of all whether he filled the chair when Paul pleaded his cause, which was some years after Felix was settled in the government. But Krebs has proved that this very Ananias, on being examined at Rome, was found innocent, returned to Jerusalem, and was restored to the high priesthood; see Joseph. Antiq. lib. xx. cap. 9, s. 2; but of his death I find nothing certain. See Krebs on this place, (Observat. in Nov. Testament. e Flavio Josepho), who successfully controverts the opinion of Dr. Lightfoot, mentioned at the beginning of this note. There was one Ananias, who is said to have perished in a tumult raised by his own son about five years after this time; see Jos. Antiq. lib. x. cap. 9. War, lib. ii. cap. 17. To smite him on the mouth - Because he professed to have a good conscience, while believing on Jesus Christ, and propagating his doctrine.
