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.

Deuteronomy 26:2

26:2 you must take the first of all the ground’s produce you harvest from the land the Lord your God is giving you, place it in a basket, and go to the place where he chooses to locate his name.

Deuteronomy 33:16

33:16 with the harvest of the earth and its fullness

and the pleasure of him who resided in the burning bush.

May blessing rest on Joseph’s head,

and on the top of the head of the one set apart from his brothers.
