In the first half of today's class, we take a historical excursion and explore some ancient textual markings in this portion and their surprising meaning and origins. Then we turn to the Children of Israel's journey to the Promised Land, and their inability to postpone gratification. We turn to the Psalms and to Rev. Dr. Martin Luther King, reminding us that when we cry "How long?" - How long must our suffering, must injustice, continue - we still must keep marching.
