Leviticus 25:28

‘You shall thus set apart as holy the fiftieth year and proclaim a release through the land to all its inhabitants. It shall be a jubilee for you, and each of you shall return to his own possession of land, and each of you shall return to his family.

‘Even if he is not redeemed by these means, he shall still go out in the year of jubilee, he and his sons with him.

‘Indeed, the seller will not return to himself what he sold as long as they both live; for the vision regarding all their multitude will not return empty, nor will any of them strengthen his life by his iniquity.
