Deuteronomy 18:1-8

1The priests the Levites, evenall the tribe of Levi, shall have no portion nor inheritance with Israel: they shall eat the offerings of Jehovah made by fire, and his inheritance. 2And they shall have no inheritance among their brethren: Jehovah is their inheritance, as he hath spoken unto them. 3And this shall be the priests’ due from the people, from them that offer a sacrifice, whether it be ox or sheep, that they shall give unto the priest the shoulder, and the two cheeks, and the maw. 4The first-fruits of thy grain, of thy new wine, and of thine oil, and the first of the fleece of thy sheep, shalt thou give him. 5For Jehovah thy God hath chosen him out of all thy tribes, to stand to minister in the name of Jehovah, him and his sons for ever.

6And if a Levite come from any of thy gates out of all Israel, where he sojourneth, and come with all the desire of his soul unto the place which Jehovah shall choose; 7then he shall minister in the name of Jehovah his God, as all his brethren the Levites do, who stand there before Jehovah. 8They shall have like portions to eat, besides that which cometh of the sale of his patrimony.
