Leviticus 25:10-17

And you shall consecrate the fiftieth year and proclaim freedom [for the slaves] throughout the land to all its inhabitants. It shall be a Jubilee (year of remission) for you, and each of you shall return to his own [ancestral] property [that was sold to another because of poverty], and each of you shall return to his family [from whom he was separated by bondage]. That fiftieth year shall be a Jubilee for you; you shall not sow [seed], nor reap what reseeds itself, nor gather the grapes of the uncultivated vines. For it is the Jubilee; it shall be holy to you; you shall eat its crops out of the field. ‘In this Year of Jubilee each of you shall return to his own [ancestral] property. If you sell anything to your friend or buy from your friend, you shall not wrong one another. According to the number of years after the Jubilee, you shall buy from your friend. And he is to sell to you according to the number of years of crops [which may be harvested before you must restore the property to him]. If the years [until the next Jubilee] are many, you shall increase the price, but if the years remaining are few, you shall reduce the price, because it is the number of crops that he is selling to you. You shall not wrong one another, but you shall fear your God [with profound reverence]; for I am the LORD your God.
