'Gleaning' in the Bible

And when ye reap the harvest of your land, thou shalt not wholly reap the corners of thy field, and the gleaning of thy harvest thou shalt not gather.

And when ye reap the harvest of your land, thou shalt not in thy harvest entirely reap the corners of thy field, and the gleaning of thy harvest shalt thou not gather: thou shalt leave them unto the poor and to the stranger: I am Jehovah your God.
