Leviticus 25
The sabbatical year and Jubilee regulations — uniquely grounded at Mount Sinai — extend the Sabbath principle from the weekly day to the seventh year (when the land rests completely from agriculture) and to the fiftieth year (the Jubilee), when all sold land returns to the original family and all Israelite debt-slaves are released. The theological foundation is the most radical ownership claim in the Torah: the land is mine, and you reside in my land as foreigners and strangers. The Jubilee transforms every land sale into a time-limited lease priced by the remaining years until the next Jubilee; property dedicated to God through a herem vow becomes permanently irrevocable. The kinsman-redeemer (goel) provision allows family members to buy back sold land before the Jubilee. Israelite debt-slaves must be treated as hired workers or temporary residents rather than permanent slaves, released with their children at the Jubilee; the theological rationale is the Exodus: the Israelites are my servants, whom I brought out of Egypt. Isaiah 61:1–2 announces a year of the Lord's favor — the Jubilee — which Jesus applies to himself in Luke 4:18–19 as the inaugural proclamation of his ministry.
