Book Seven compiles rabbinic law on such topics as the planting of seeds and the propagation of domestic animals, specific tithes owed to priests and Levites, portions of crops to be consumed by the grower, the Sabbatical and Jubilee years, and the giving of gifts to the poor. Also included is Maimonides' formulation of the Eight Degrees of Charity. The laws codified here have guided the tradition of charity that continues to the present day in the Jewish community.
