Moishe the Beadle is the first character we meet in Night. In a way, he is a character who determines and marks Eliezer's life - first, by teaching him the mystic Kabbalah (which his father disapproves of); second, by warning the local Jews of the extermination that awaits them by the Nazi regime. Therefore, Moishe is an epitome of Wiesel's main idea: that people should never ignore oppression, or try to stay neutral towards it. Moishe speaks, but people hardly believe him, if at all. He is a kind of a prophet, who foresees the future (based on his own experience), but it is all in vain, because people are prone to turn a blind eye until it gets too late.
