Deuteronomy 12:11

12:11 Then you must come to the place the Lord your God chooses for his name to reside, bringing everything I am commanding you – your burnt offerings, sacrifices, tithes, the personal offerings you have prepared, and all your choice votive offerings which you devote to him.

Deuteronomy 24:19

24:19 Whenever you reap your harvest in your field and leave some unraked grain there, 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.
