Class One. The classic discussion of Chassidus on this Possuk is repeated here. The journeys from Egypt and through the desert are ירידה צורך עלי’ה on two levels: 1) The Yidden have an Aliya. 2) They took along and elevated the sparks of Mitzrayim. Thus the departure is really taking Egypt along. Thus the reference to the travels.
Class Two. In this class the Avoda relevance of the recounting of the Jewish journey is explained and it helps us answer questions that (otherwise) remained unanswered. In other words: The Avoda assists the Haskala. מוצאיהם למסעיהם and מסעיהם למן צאיהם are two aspects of the Journey of life: 1) From the top down; Mitzvos. 2) from the bottom up: Prayer. The power behind both is Torah. This is why the recounting must involve both Moshe and Aharon as they represent these two themes.
