"Throughout the land of your possession, you shall give redemption for the land"—Leviticus 25:24.

During the Jubilee Year, all acquired land must be returned – free of charge – to its original owner, as explained in the Torah.

This mitzvah applies only to real estate that is not within a walled city, and is only practiced in the Land of Israel, and only when all of the tribes are settled therein, each in their ancestral portion of the Land.
