5 For he, and his sons after him for ever, have been marked out by the Lord your God from all your tribes, to do the work of priests in the name of the Lord.

Matthew Henry's Commentary on Deuteronomy 18:5

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.
