Which Jewish law emphasizes the need for land to rest every seven years?

The law that emphasizes the need for land to rest every seven years is known as Shmitah. This agricultural commandment is rooted in the Torah and serves to promote concepts of sustainability and environmental responsibility in farming practices. According to Shmitah, during the seventh year of the agricultural cycle, fields should lie fallow, and debts among the people are forgiven; this practice not only allows the land to recover and rejuvenate but also exhibits a commitment to social justice by alleviating the burdens of debt.

The other concepts, while relevant to Jewish practice, do not pertain specifically to the resting of land. Shabbat refers to the weekly day of rest, Kol Nidre is a prayer recited on Yom Kippur related to vows, and Seder is a ritual meal during Passover. None of these directly address the agricultural principle of land resting every seven years, which is the core focus of Shmitah.
