One would not think there had been so much need as it seems there was to arm the people of Israel against the infection of the idolatrous customs of the Canaanites. Was it possible that a people so blessed with divine institutions should ever admit the brutish and barbarous inventions of men and devils? Were they in any danger of making those their tutors and directors in religion whom God had made their captives and tributaries? It seems they were in danger, and therefore, after many similar cautions, they are here charged not to do after the abominations of those nations, Deut. 18:9.
I. Some particulars are specified; as, 1. The consecrating of their children to Moloch, an idol that represented the sun, by making them to pass through the fire, and sometimes consuming them as sacrifices in the fire, Deut. 18:10. See the law against this before, Lev. 18:21. 2. Using arts of divination, to get the unnecessary knowledge of things to come, enchantments, witchcrafts, charms, etc., by which the power and knowledge peculiar to God were attributed to the devil, to the great reproach both of God’s counsels and of his providence, Deut. 18:10, 11. One would wonder that such arts and works of darkness, so senseless and absurd, so impious and profane, could be found in a country where divine revelation shone so clearly; yet we find remains of them even where Christ’s holy religion is known and professed; such are the powers and policies of the rulers of the darkness of this world. But let those give heed to fortune-tellers, or go to wizards for the discovery of things secret, that use spells for the cure of diseases, are in any league or acquaintance with familiar spirits, or form a confederacy with those that are—let them know that they can have no fellowship with God while thus they have fellowship with devils. It is amazing to think that there should by any pretenders of this kind in such a land and day of light as we live in.
II. Some reasons are given against their conformity to the customs of the Gentiles. 1. Because it would make them abominable to God. The things themselves being hateful to him, those that do them are an abomination; and miserable is that creature that has become odious to its Creator, Deut. 18:12. See the malignity and mischievousness of sin; that must needs be an evil thing indeed which provokes the God of mercy to detest the work of his own hands. 2. Because these abominable practices had been the ruin of the Canaanites, of which ruin they were not only the witnesses but the instruments. It would be the most inexcusable folly, as well as the most unpardonable impiety, for them to practise themselves those very things for which they had been employed so severely to chastise others. Did the land spue out the abominations of the Canaanites, and shall Israel lick up the vomit? 3. Because they were better taught, Deut. 18:13, 14. It is an argument like that of the apostle against Christians walking as the Gentiles walked (Eph. 4:17, 18, 20): You have not so learned Christ. “It is true these nations, whom God gave up to their own hearts’ lusts, and suffered to walk in their own ways (Acts 14:16), did thus corrupt themselves; but thou art not thus abandoned by the grace of God: the Lord thy God had not suffered thee to do so; thou art instructed in divine things, and hast fair warning given thee of the evil of those practices; and therefore, whatever others do, it is expected that thou shouldest be perfect with the Lord thy God,” that is, “that thou shouldest give divine honours to him, to him only, and to no other, and not mix any of the superstitious customs of the heathen with his institutions.” One of the Chaldee paraphrasts here takes notice of God’s furnishing them with the oracle of urim and thummim, as a preservative from all unlawful arts of divination. Those were fools indeed who would go to consult the father of lies when they had such a ready way of consulting the God of truth.
