Leviticus 19:9-11

9‘1Now when you reap the harvest of your land, you shall not reap to the very edges of your field, nor shall you gather the gleanings of your harvest. 10And you shall not glean your vineyard, nor shall you gather the fallen grapes of your vineyard; you shall leave them for the needy and for the stranger. I am the Lord your God.

11‘2You shall not steal, nor deal falsely, 3nor lie to one another.
