10 For example, never sacrifice your son or daughter as a burnt offering. And do not let your people practice fortune-telling, or use sorcery, or interpret omens, or engage in witchcraft, 11 or cast spells, or function as mediums or psychics, or call forth the spirits of the dead. 12 Anyone who does these things is detestable to the Lord . It is because the other nations have done these detestable things that the Lord your God will drive them out ahead of you.
Matthew Henry's Commentary on Deuteronomy 18:10-12
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.
