While being confined at Yodfat (Jotapata), Josephus claimed to have experienced a divine revelation that later led to his speech predicting Vespasian would become emperor. After the prediction came true, he was released by Vespasian, who considered his gift of prophecy to be divine. Josephus wrote that his revelation had taught him three things: that God, the creator of the Jewish people, had decided to "punish" them; that "fortune" had been given to the Romans; and that God had chosen him "to announce the things that are to come". To many Jews, such claims were simply self-serving.
