There are many Biblical allusions in Night. For example, there are references to the Jewish exile in Babylon, a story told in the Bible. When Elie describes the way in which the Jewish community is forced to leave Sighet, he says, "Saturday, the day of rest, was the day chosen for our expulsion" (21). This expulsion recalls the Jewish exile in Babylon. Another event, the closing of the town's synagogue--Elie says, "The synagogues were no longer open" on page 10--is an allusion to Romans' destruction of the Jewish temple in Jerusalem in 70 CE.
Later, Elie writes of the arrival of the Nazis in his town, "On the seventh day of Passover, the curtain finally rose: the Germans arrested the leaders of the Jewish community" (10). The fact that the Nazis' actions begin around Passover is an allusion to the destruction of the temple in ancient times (as the Romans began their attack on Jerusalem right before Passover), and it's also an allusion to the Jews' exile from Egypt during Passover, told in the Biblical book of Exodus.
When Elie and his father are being marched towards the pit in the concentration camp, Elie says, "My heart was about to burst. There. I was face-to-face with the Angel of Death" (34). The Angel of Death alludes to the angel Azrael in the Old Testament. Later, in a harrowing scene, Elie walks by the hanging body of a dead boy who the Nazis put on the gallows, saying "Then the entire camp, block after block, filed past the hanged boy and stared at his extinguished eyes, the tongue hanging from his gaping mouth" (62-63). This scene is in part an allusion to the Biblical story of Abraham, who is called by God to sacrifice his son, Isaac.
On page 78 and 79, Elie Weisel! During a conversation with God, says, "But these men here, whom you have betrayed, whom you have allowed to be tortured ans butchered."
A second allusion is the flames of the fires in the novel represent The devil and hell. The flames can also beconsidered a metaphor for death which is prevalent throughout he entire novel.
Weisel also refers to the concentration camps as Calvary. Calvary is the place where the Jews took Christ to be crucified. The Germans and officers were compared to Man and sun and the Jews were compared to God as the good ones. God kept his promises to those Jews that were faithful in the end.
The silent God that Weisel refers to When the young boy is hanged is giving reference to the story of Isaac and Abraham. This was where God tested Abraham by telling hm to sacrifice his son to prove his devotion to God. This reference has a twist though. Whereas Isaac was saved, the young boy in this story was not.
This same scene also refers to the image of Christ hanging on the cross. It is noted that Christ was hung at the gallows between two thieves and the young boy was also hung with other people before a watchful audience, just as Christ.
