6 And if a Levite, moved by a strong desire, comes from any town in all Israel where he is living to the place marked out by the Lord; 7 Then he will do the work of a priest in the name of the Lord his God, with all his brothers the Levites who are there before the Lord. 8 His food will be the same as theirs, in addition to what has come to him as the price of his property.

Warning against Heathen Practices

9 When you have come into the land which the Lord your God is giving you, do not take as your example the disgusting ways of those nations. 10 Let there not be seen among you anyone who makes his son or his daughter go through the fire, or anyone using secret arts, or a maker of strange sounds, or a reader of signs, or any wonder-worker,

Matthew Henry's Commentary on Deuteronomy 18:6-10

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.

Commentary on Deuteronomy 18:9-14

(Read Deuteronomy 18:9-14)

Was it possible that a people so blessed with Divine institutions, should ever be in any danger of making those their teachers whom God had made their captives? They were in danger; therefore, after many like cautions, they are charged not to do after the abominations of the nations of Canaan. All reckoning of lucky or unlucky days, all charms for diseases, all amulets or spells to prevent evil, fortune-telling, &c. are here forbidden. These are so wicked as to be a chief cause of the rooting out of the Canaanites. It is amazing to think that there should be any pretenders of this kind in such a land, and day of light, as we live in. They are mere impostors who blind and cheat their followers.
