 When Gamaliel II was temporarily deposed from the patriarchate due to his provoking demeanor, Eleazar, though still very young, was elevated to that office by the deliberate choice of his colleagues.He did not, however, occupy it for any length of time, for the Sanhedrin reinstated Gamaliel.Nevertheless he was retained as vice-president ("ab bet din"), and it was arranged that Gamaliel should lecture three (some say two) Sabbaths, and Eleazar every fourth (or third) Sabbath.
