Eliezer is an orthodox Jewish young boy of twelve years old. He daily meditates on scriptures in Torah, praying everyday, etc. Elie's father tried to maintain Jewish traidtion in his family.
In concentration camp, when Elie's father became ill and died, Elie took the responsibility to maintain the Jewish tradition in his family. This is the role reversal that took place when Eliezer's father became ill.
