Rabbi Diamond writes that rituals of closure, common in both secular and religious settings, relate to the past and to the future, creating a space in which one begins anew. When we finish a book of the Torah, we conclude with a ritual chanting of hazak hazak. This is appropriate for the completion of Shemot, which ends on a high note.
Sam Shonkoff writes about the phrase bitul Torah – cancellation of Torah; this refers to the time one spends away from study, dealing with chol, or profane (secular) issues. The concept suggests that religious life only occur with the framework of ritual. Yet, spiritual life is actually continuous; what one does during the week is as important as what one does during religious rituals.
Rabbi Sacks writes about the different words for community: edah – people who have a strong sense of collective identity; tzibbur – members have nothing in common but happen to find themselves to gather; kehillah – members gather together for a collective undertaking. It is the latter type of community that can be dangerous; a rabble or a crowd. This is what Moses sees when he descends the mountain.
