Deuteronomy 24:19-21

New Revised Standard Version Catholic Edition

¹⁹ When you reap your harvest in your field and forget a sheaf in the field, you shall not go back to get it; it shall be left for the alien, the orphan, and the widow, so that the Lord your God may bless you in all your undertakings. ²⁰ When you beat your olive trees, do not strip what is left; it shall be for the alien, the orphan, and the widow.

²¹ When you gather the grapes of your vineyard, do not glean what is left; it shall be for the alien, the orphan, and the widow.
