It is true that under the Roman governors the high priests were frequently changed (cf. above, chap. 6, note 19), but there was no regularly prescribed interval, and some continued in office for many years; for instance, Caiaphas was high priest for more than ten years, during the whole of Pilate’s administration, having been appointed by Valerius Gratus, Pilate’s predecessor, and his successor being appointed by the Proconsul Vitellius in 37 a.d. (vid. Josephus, Ant. XVIII. 2. 2 and 4. 3).
