Moshe the Beadle believes that he has returned to Sighet to warn the townspeople of the Nazi threat.

Moshe's story starts with being expelled from Sighet.  When he returns, Moshe talks to anyone who will listen his story.  His story consists of how Jewish people like himself were ordered to dig trenches.  Then, one by one, the Nazis killed them.  The Nazis used infants as target practice.  Moshe hid amongst the dead bodies, and pretended he was dead. He believed that he was chosen to live so he could warn others of his experience. 

However, when the people of Sighet heard his story, they refused to believe him.  Some said that Moshe made up the story because he wanted pity. Others claimed that he had "gone mad" or that Moshe wanted money.  Moshe ends weeping because he is not believed and leaves Sighet once and for all.

Wiesel uses the story of Moshe the Beadle to show how dehumanization was a significant aspect of the Holocaust.  The Nazis dehumanized their victims, and, in turn, Wiesel suggests that some of the victims dehumanized one another. In the presentation of Moshe's story, Wiesel argues that the Holocaust is the net result of human cruelty towards one another.
