Ulangan 12:17

12:17 You will not be allowed to eat in your villages your tithe of grain, new wine, olive oil, the firstborn of your herd and flock, any votive offerings you have vowed, or your freewill and personal offerings.

Ulangan 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 

[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).
