How are the Bible’s weekly Sabbath, sabbatical years and the 50-year Jubilee actually linked? And what do they reveal about debt, poverty, land use and Israel’s modern history? In this deep-dive study of Leviticus, Deuteronomy and Jeremiah, we connect Torah cycles to Mark Twain’s haunting visit to Jerusalem, modern agriculture and God’s long memory. Discover why ignoring divine rest laws reshapes economies, communities and even empires — and why generous release of debts may still change our future in ways we rarely expect.
