Setting. The Hunger Games trilogy takes place in an unspecified future time, in the dystopian, post-apocalyptic nation of Panem, located in North America. The country consists of a wealthy Capitol city, located in the Rocky Mountains, surrounded by twelve (originally thirteen) poorer districts ruled by the Capitol.

Elie and the other Jewish prisoners in the camp practiced their faith in as much as they can, praying before eating, singing songs before sleeping, observing the important festivals, etc.

But as the days of the captivity increase, Elie began to question God's silence and even His existence amidst the suffering of His people.  

Explanation:

Elie Wiesel's memoir Night tells the first-hand experience of the Holocaust and its repercussions on the Jewish people during the German's discriminating acts against the race. The book became one of the most important books and evidence or source to study the events of the discrimination of the Jewish people during the Nazis' regime.

The prisoners along with Elie managed to keep their tradition and religion through the small acts of praying before eating, and at times fasting and singing Hasidic melodies. They also observed the New Year celebration and observed the festival of Yom Kippur, despite their already starving condition in the camps.

At first, Elie also had a strong belief in God. He kept his religious faith and practices as much as he can. But the longer he stayed in the camps, the more he saw of the suffering of "God's chosen people". This angered him and he began to question whether there is really a God and if there is, why He would allow his people to suffer such misfortunes and sufferings. Since his own captivity, his belief in God began to decrease and began to question God's silence and existence at the face of His people's suffering.
