Matthew Henry Commentary Deuteronomy 18:1-8

"The priests the Levites, [even] all 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. And they shall have no inheritance among their brethren: Jehovah is their inheritance, as he hath spoken unto them. And 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. The 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. For 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. And 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; then he shall minister in the name of Jehovah his God, as all his brethren the Levites do, who stand there before Jehovah. They shall have like portions to eat, besides that which cometh of the sale of his patrimony." — Deuteronomy 18:1-8 (ASV)

Care is taken that the priests do not entangle themselves with the affairs of this life, nor enrich themselves with the wealth of this world; they have better things to attend to. Care is likewise taken that they do not lack the comforts and conveniences of this life. The people must provide for them. Anyone who has the benefit of solemn religious assemblies should contribute to the comfortable support of those who minister in such assemblies.
