In this shiur, delivered in Tomer Devorah (last shiur of the year), Rav Burg explains how Shemita and Yovel rectify the sin of Kayin and Hevel. As one journeys through the story of Kayin and Hevel to Lemech and his wives and four children and finally to Shes and his ultimate descendant Noach it becomes clear that the narrative is about the loss of Tzelem Elokim and the dangers of living in an animal society. Ultimately a society that loses its awareness of its own Godliness will destroy itself. Shemita and Yovel bring us back to true freedom and restore our Godly dignity.
