Night represents the worst periods of suffering during Eliezer's experience of the Holocaust. In Sighet, the Jews learn of their deportation at night. Eliezer arrives at Birkenau at night. The death march to Gleiwitz happens at night. At Buchenwald, his father is taken away during the night. Night also symbolizes the hole—the absence—left in Eliezer's life as a religious person who comes to a personal realization that God does not exist.
