Leviticus 19:9; Leviticus 19:10

9 'Now when you reap the harvest of your land, you shall not reap to the very corners of your field, nor shall you gather the gleanings of your harvest.

10 'Nor shall you glean your vineyard, nor shall you gather the fallen fruit of your vineyard; you shall leave them for the needy and for the stranger. I am the LORD your God.
