Leviticus 19:9

When you reap the harvest of your land , you shall not reap your field right up to its edge , neither shall you gather the gleanings after your harvest .

“‘When you reap the harvest of your land, do not reap to the very edges of your field or gather the gleanings of your harvest.

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.
