Leviticus 25:10-13

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.
