'Uncultivated' in the Bible

Whatever reseeds itself (uncultivated) in your harvest you shall not reap, nor shall you gather the grapes from your uncultivated vine, it shall be a year of sabbatical rest for the land.

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.
