9 "When you come into the land which the Lord your God gives you, you shall not learn to follow the abominable practices of those nations. 10 There shall not be found among you any one who burns his son or his daughter as an offering, any one who practices divination, a soothsayer, or an augur, or a sorcerer, 11 or a charmer, or a medium, or a wizard, or a necromancer. 12 For whoever does these things is an abomination to the Lord; and because of these abominable practices the Lord your God is driving them out before you. 13 You shall be blameless before the Lord your God. 14 For these nations, which you are about to dispossess, give heed to soothsayers and to diviners; but as for you, the Lord your God has not allowed you so to do.
15 "The Lord your God will raise up for you a prophet like me from among you, from your brethren--him you shall heed-- 16 just as you desired of the Lord your God at Horeb on the day of the assembly, when you said, 'Let me not hear again the voice of the Lord my God, or see this great fire any more, lest I die.' 17 And the Lord said to me, 'They have rightly said all that they have spoken. 18 I will raise up for them a prophet like you from among their brethren; and I will put my words in his mouth, and he shall speak to them all that I command him. 19 And whoever will not give heed to my words which he shall speak in my name, I myself will require it of him. 20 But the prophet who presumes to speak a word in my name which I have not commanded him to speak, or who speaks in the name of other gods, that same prophet shall die.' 21 And if you say in your heart, 'How may we know the word which the Lord has not spoken?' -- 22 when a prophet speaks in the name of the Lord, if the word does not come to pass or come true, that is a word which the Lord has not spoken; the prophet has spoken it presumptuously, you need not be afraid of him.

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.
