6 If a Levite leaves any of your towns, from wherever he has been residing in Israel, and comes to the place that the Lord will choose (and he may come whenever he wishes), 7 then he may minister in the name of the Lord his God, like all his fellow-Levites who stand to minister there before the Lord. 8 They shall have equal portions to eat, even though they have income from the sale of family possessions.

Warning against Heathen Practices

9 When you come into the land that the Lord your God is giving you, you must not learn to imitate the abhorrent practices of those nations. 10 No one shall be found among you who makes a son or daughter pass through fire, or who practices divination, or is a soothsayer, or an augur, or a sorcerer,

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.
