When you reap the harvest of your land, you are not to reap to the very edges of your field or gather the gleanings of your harvest.
KJV
And when ye reap the harvest of your land, thou shalt not wholly reap the corners of thy field, neither shalt thou gather the gleanings of thy harvest.
ASV
And when ye reap the harvest of your land, thou shalt not wholly reap the corners of thy field, neither shalt thou gather the gleaning of thy harvest.
