Why do you thuink elie wiesel begins Night with the story of moshe the beadle?

Moishe is a Jewish man living in Sighet. He is somewhat like a teacher to Elie, helping him to learn Kabbalah. He also returns to Sighet and warns the Jews of what is to come but they do not listen. He is like a prophet.

I believe Elie began the story with him as a way to introduce religion, faith, and also to show that nobody listened when they were warned. His loss of faith sets a theme for the book.
