Deuteronomy 12:17-19

Thou mayest not eat within thy gates the tithe of thy grain, or of thy new wine, or of thine oil, or the firstlings of thy herd or of thy flock, nor any of thy vows which thou vowest, nor thy freewill-offerings, nor the heave-offering of thy hand; but thou shalt eat them before Jehovah thy God in the place which Jehovah thy God shall choose, thou, and thy son, and thy daughter, and thy man-servant, and thy maid-servant, and the Levite that is within thy gates: and thou shalt rejoice before Jehovah thy God in all that thou puttest thy hand unto. Take heed to thyself that thou forsake not the Levite as long as thou livest in thy land.
