2 but they shall have no inheritance among their brethren: Jehovah, he is their inheritance, as he hath said unto them. 3 And this shall be the priest's due from the people, from them that sacrifice a sacrifice, whether ox, or sheep: they shall give unto the priest the shoulder, and the jawbones, and the maw. 4 The firstfruits [also] of thy corn, of thy new wine, and of thine oil, and the firstfruits of the shearing of thy sheep, shalt thou give him; 5 for Jehovah thy God hath chosen him out of all thy tribes, that he may stand to serve in the name of Jehovah, he and his sons continually.
Matthew Henry's Commentary on Deuteronomy 18:2-5
Commentary on Deuteronomy 18:1-8
(Read Deuteronomy 18:1-8)
Care is taken that the priests entangle not themselves with the affairs of this life, nor enrich themselves with the wealth of this world; they have better things to mind. Care is likewise taken that they want not the comforts and conveniences of this life. The people must provide for them. He that has the benefit of solemn religious assemblies, ought to give help for the comfortable support of those that minister in such assemblies.
