Leviticus 25:10, 13, 28
So you are to consecrate the fiftieth year and proclaim liberty in the land for all its inhabitants. It shall be your Jubilee, when each of you is to return to his property and to his clan. / In this Year of Jubilee, each of you shall return to his own property. / But if he cannot obtain enough to repay him, what he sold will remain in possession of the buyer until the Year of Jubilee. In the Jubilee, however, it is to be released, so that he may return to his property.
Leviticus 27:24
In the Year of Jubilee the field shall return to the one from whom it was bought—the original owner of the land.
