Shamat (H8058) is the verb behind the Sabbatical Year (shemitah) β every seventh year, the land is released, debts are forgiven, and Hebrew slaves are freed. The concept encodes God's economics of grace: nothing is ultimately owned, everything belongs to Him, and periodically the whole system is released back to its original design.
Deuteronomy 15 describes the full shemitah practice β release of debts, freeing of bondservants, and generous giving. Shamat embodies the theological principle that clinging and accumulation is against God's design. The Jubilee (every 50 years) extended shamat to land itself. Jesus echoes this in forgiving debts as the Father forgives (Matthew 6:12).
