How does Elie Wiesel establish the setting of Night in the opening chapter?

In the book Night, Elie Wiesel uses several ideas to establish the setting.  At the beginning of Chapter 1, when Moishe the Beadle is being described, the author also describes the town of Sighet, a small Jewish town in Transylvania. Elie describes the transporting of the foreign Jews from his small town, which illustrates the German intent to capture and transport the Jews; at this point, the setting in which they gather Jews together to transport them, even in the cold, is established. Elie describes sitting with Moishe when he returns from his exile and persuades Moishe to teach Elie. He also describes sitting with his family listening to the London radio broadcast. Elie describes the eight days of Passover, the German entrance into their town, the imposition of the yellow star, and most of all, the creation of the ghettos. Two ghettos are created and in a very casual way, Elie outlines all the changes for the Jews, such as giving up space in their homes for relatives who lost their homes.  

Each change that Elie describes gives readers another look at the setting, from the beginning where life is good and no one is fearful, to the creation of the ghettos and finally, the fearful boarding of the trains.
