Why is Parsha Truma so significant to Vladek?

Three months later it is Parshas Truma, and the prisoners are lined up in the main courtyard. He is made to sign a release form, and he is free to go. Vladek's dream about Parshas Truma has come true. Chapter 3 also includes Vladek's first - and only - mention of the Jewish religion within the pages of the story.
