Leviticus 19:9-10

“ ‘When you harvest your crops on your land, do not harvest all the way to the corners of your fields. If grain falls onto the ground, don’t gather it up. Don’t pick all the grapes in your vineyards, and don’t pick up the grapes that fall to the ground. You must leave those things for poor people and for people traveling through your country. I am the LORD your God.
