'Gleanings' in the Bible

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.

When you reap the harvest of your land, you are not to reap all the way to the edge of your field or gather the gleanings of your harvest. Leave them for the poor and the foreign resident; I am Yahweh your God.”
