Deuteronomy 12:17-19

17Thou mayest not eat within thy gates the tithe of thy corn, or of thy new wine, or of thine oil, or the firstlings of thy kine or of thy sheep, nor any of thy vows which thou vowest, nor thy voluntary-offerings, nor the heave-offering of thy hand;

18but before Jehovah thy 1God shalt thou eat them in the place which Jehovah thy 2God will choose, thou and thy son, and thy daughter, and thy bondman, and thy handmaid, and the Levite that is within thy gates; and thou shalt rejoice before Jehovah thy 3God in all the business of thy hand.

19Take heed to thyself that thou forsake not the Levite all the days thou shalt be in thy land.
