Verses 9-22. - Moses was not only the leader and ruler of the people, he was also the medium through which God communicated with the people, gave them his laws, and conveyed to them his word and will. In this respect his place could be supplied neither by priest nor by king. In the prospect of his demise, therefore, there required to be instituted another office, that of a prophet, one who should be between God and the people, as the channel through which Divine communications might pass to them. This office Moses here announces that God would establish among them when they had entered the Promised Land. Verse 9. - The abominations of these nations; i.e. certain forms of superstitious usage by which the heathen sought to procure the favor of their deities, to obtain from them direction and counsel, and to penetrate into the hidden future of events. Moses charges the people to avoid all such usages, and not even to learn to do after such abominations (cf. Leviticus 18:21; Numbers 23:23; Leviticus 19:26, 31).
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.
When thou art come into the land which the Lord thy God giveth thee,.... The land of Canaan, often thus described, to express the goodness of God in bestowing it on them, as a mere favour of his, without any desert of theirs; and so typical of the heavenly Canaan, or eternal life, which is the free gift of God through Christ:
thou shall not learn to do after the abominations of these nations; the seven nations which before inhabited it; they might learn, as Jarchi observes, to know how corrupt their works were, and to show to their children, that they might not do so; but they were not to learn them so as to practise them, but to have them in the utmost abhorrence, as being abominable to God, and which should be so to them; some of which are as follow.
