And the LORD spoke on Mount Sinai: “When you come into the land that I am about to give you, the land shall keep a Sabbath to the LORD.” Rashi asks why the Torah expressly mentions the Sabbatical year as a commandment that was taught at Sinai. During the Sabbatical year tilling the soil is forbidden and a person is given a chance to turn inward and regain control of their life. In some sense, this is the goal of all the commandments that were given at Sinai. At first they appear to forbid many activities, but their overarching purpose is to give us a chance to turn inward and be in control of our life.
