Deuteronomy 24:19

24:19 Whenever you reap your harvest in your field and leave some unraked grain there, ¹  you must not return to get it; it should go to the resident foreigner, orphan, and widow so that the Lord your God may bless all the work you do. ² 

Leviticus 19:9-10

Leaving the Gleanings

19:9 “‘When you gather in the harvest ³  of your land, you must not completely harvest the corner of your field, ⁴  and you must not gather up the gleanings of your harvest. 19:10 You must not pick your vineyard bare, ⁵  and you must not gather up the fallen grapes of your vineyard. You must leave them for the poor and the foreigner. I am the Lord your God.

[24:19]  ¹ tn Heb “in the field.”

[24:19]  ² tn Heb “of your hands.” This law was later applied in the story of Ruth who, as a poor widow, was allowed by generous Boaz to glean in his fields (Ruth 2:1-13).

[19:9]  ³ tn Heb “And in your harvesting the harvest.”

[19:9]  ⁴ tn Heb “you shall not complete the corner of your field to harvest.”

[19:10]  ⁵ tn Heb “And you shall not deal severely with your vineyard.”
