Deuteronômio 14

22 Thou shalt separate the tenth part of all thy fruits that come forth in the land by each year;

29 And the deacon [or Levite] shall come, that hath none other part nor possession with thee, and the pilgrim, and the fatherless, either motherless child, and the widow, that be within thy gates, and they shall eat, and be fulfilled, that thy Lord God bless thee, in all the works of thine hands which thou shalt do.
