Parashat Vaethanan is filled with well-known passages, including the Ten Commandments and the Shema. Reciting the Shema is seen as fulfilling the mitzvah of accepting the Yoke of Heaven. This shiur is devoted to developing a deeper appreciation of the first verse of Shema. Though only six words, it is a difficult text. We raise questions and examine the readings of various classical commentators, exploring historical, theological and philosophical readings which enrich our experience of this famous and meaningful declaration.
