The Sabbath being the sign of God's covenant with Israel (See SABBATH), and that He purposed that they should enjoy His rest, even the land must keep its Sabbath every seventh year. God promised that the produce of the sixth year should be enough for three years, so that the land resting a full year should cause no scarcity. Exodus 23:10,11; Leviticus 25:2-7 . Apparently the Sabbatical years were not observed. Leviticus 26:33-35 . See JUBILEE.
