2 and he hath no inheritance in the midst of his brethren; Jehovah Himself 'is' his inheritance, as He hath spoken to him. 3 'And this is the priest's right from the people, from those sacrificing a sacrifice, whether ox or sheep, he hath even given to the priest the leg, and the two cheeks, and the stomach; 4 the first of thy corn, of thy new wine, and of thine oil, and the first of the fleece of thy flock, thou dost give to him; 5 for on him hath Jehovah thy God fixed, out of all thy tribes, to 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.
