10 there is not found in thee one causing his son and his daughter to pass over into fire, a user of divinations, an observer of clouds, and an enchanter, and a sorcerer, 11 and a charmer, and one asking at a familiar spirit, and a wizard, and one seeking unto the dead. 12 'For the abomination of Jehovah 'is' every one doing these, and because of these abominations is Jehovah thy God dispossessing them from thy presence. 13 Perfect thou art with Jehovah thy God, 14 for these nations whom thou art possessing, unto observers of clouds, and unto diviners, do hearken; and thou—not so hath Jehovah thy God suffered thee.
Matthew Henry's Commentary on Deuteronomy 18:10-14
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.
