Gratus restructured the Temple leadership, promoting and demoting people
until he found someone he liked. He first deposed Annas (also called
Ananus), who is known as one of Jesus' two chief antagonists, and later
promoted Joseph Caiaphas, Jesus' other enemy within the Temple. The
succession of chief priests goes as follows: Annas (A.D. 6 to 15),
Ishmael (15 to 16), Eleazar (16 to 17), Simon (17 to 18), and Caiaphas
(18 to 36) to be followed by others.
