Aliya Summary: The Torah sets the punishments for individuals who curse their parents and those who engage in prohibited sexual relations. We are instructed not to follow the customs and traditions of the heathens, and to be meticulous about eating only kosher foods. The Torah portion ends with an rejoinder that we be holy.
Notice the dual role that every Jew must play. We are each individuals and we are part of Klal Yisrael. We are exhorted to keep the Torah as individuals, but we are also “advised” to be faithful to G-d so that tragedies will not happen to the People of Israel as a whole.
