Leviticus 19:9
"'When you reap the harvest of your land, you shall not wholly reap the corners of your field, neither shall you 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.

What Leviticus 19:9 means
God tells farmers to leave the edges of their fields uncut and to walk past whatever they drop, so that people with nothing can come and gather food for themselves.
Picture a farmer bringing in the harvest. Every instinct says get all of it: work the field right into the corners, go back for anything that fell. God says stop short. Leave the edges standing, and whatever drops, let it lie.
The reason is who is standing at the edge of the field. In that world, if you owned no land, you had no way to feed yourself, and plenty of people owned nothing: widows, orphans, foreigners a long way from home. This law hands them a corner of someone else's field and says the food there is theirs. And they do not wait around for anyone to give it to them. They walk in and gather it with their own hands. It is help that still lets a person work, and being able to work is a big part of holding on to your dignity.
This is the very thing Ruth does a few books later. She is a widow and a foreigner with nothing, and she keeps herself and her mother-in-law alive by following the harvesters through a stranger's field, picking up what they left behind. The law was not a nice idea on a scroll. It was what stood between her and going hungry.
You can still feel what it is after. There is a world of difference between being handed a little something and being given a real way to feed yourself. The first can leave you smaller than before. The second lets you keep your head up while you do the work.
