9 When you come into the land that the Lord your God is giving you, you must not learn to imitate the abhorrent practices of those nations. 10 No one shall be found among you who makes a son or daughter pass through fire, or who practices divination, or is a soothsayer, or an augur, or a sorcerer, 11 or one who casts spells, or who consults ghosts or spirits, or who seeks oracles from the dead. 12 For whoever does these things is abhorrent to the Lord; it is because of such abhorrent practices that the Lord your God is driving them out before you. 13 You must remain completely loyal to the Lord your God. 14 Although these nations that you are about to dispossess do give heed to soothsayers and diviners, as for you, the Lord your God does not permit you to do so.
15 The Lord your God will raise up for you a prophet like me from among your own people; you shall heed such a prophet. 16 This is what you requested of the Lord your God at Horeb on the day of the assembly when you said: "If I hear the voice of the Lord my God any more, or ever again see this great fire, I will die." 17 Then the Lord replied to me: "They are right in what they have said. 18 I will raise up for them a prophet like you from among their own people; I will put my words in the mouth of the prophet, who shall speak to them everything that I command. 19 Anyone who does not heed the words that the prophet shall speak in my name, I myself will hold accountable. 20 But any prophet who speaks in the name of other gods, or who presumes to speak in my name a word that I have not commanded the prophet to speak-that prophet shall die." 21 You may say to yourself, "How can we recognize a word that the Lord has not spoken?" 22 If a prophet speaks in the name of the Lord but the thing does not take place or prove true, it is a word that the Lord has not spoken. The prophet has spoken it presumptuously; do not be frightened by it.

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.
Commentary on Deuteronomy 18:15-22
(Read Deuteronomy 18:15-22)
It is here promised concerning Christ, that there should come a Prophet, great above all the prophets; by whom God would make known himself and his will to the children of men, more fully and clearly than he had ever done before. He is the Light of the world, John 12:48. Woe then to those who refuse to hearken to His voice, to accept His salvation, or yield obedience to His sway! But happy they who trust in Him, and obey Him. He will lead them in the paths of safety and peace, until He brings them to the land of perfect light, purity, and happiness. Here is a caution against false prophets. It highly concerns us to have a right touchstone wherewith to try the word we hear, that we may know what that word is which the Lord has not spoken. Whatever is against the plain sense of the written word, or which gives countenance or encouragement to sin, we may be sure is not that which the Lord has spoken.
