6 If a Levite comes from any of your gates out of all Israel, where he lives as a foreigner, and comes with all the desire of his soul to the place which Yahweh shall choose; 7 then he shall minister in the name of Yahweh his God, as all his brothers the Levites do, who stand there before Yahweh. 8 They shall have like portions to eat, besides that which comes of the sale of his patrimony.

Warning against Heathen Practices

9 When you are come into the land which Yahweh your God gives you, you shall not learn to do after the abominations of those nations. 10 There shall not be found with you anyone who makes his son or his daughter to pass through the fire, one who uses divination, one who practices sorcery, or an enchanter, 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.
