Warning against Heathen Practices

9 "When you enter the land the Lord your God is giving you, be very careful not to imitate the detestable customs of the nations living there. 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. 13 But you must be blameless before the Lord your God. 14 The nations you are about to displace consult sorcerers and fortune-tellers, but the Lord your God forbids you to do such things."

God Promises a Prophet like Moses

15 Moses continued, "The Lord your God will raise up for you a prophet like me from among your fellow Israelites. You must listen to him. 16 For this is what you yourselves requested of the Lord your God when you were assembled at Mount Sinai. You said, 'Don't let us hear the voice of the Lord our God anymore or see this blazing fire, for we will die.' 17 "Then the Lord said to me, 'What they have said is right. 18 I will raise up a prophet like you from among their fellow Israelites. I will put my words in his mouth, and he will tell the people everything I command him. 19 I will personally deal with anyone who will not listen to the messages the prophet proclaims on my behalf. 20 But any prophet who falsely claims to speak in my name or who speaks in the name of another god must die.' 21 "But you may wonder, 'How will we know whether or not a prophecy is from the Lord ?' 22 If the prophet speaks in the Lord 's name but his prediction does not happen or come true, you will know that the Lord did not give that message. That prophet has spoken without my authority and need not be feared.

Matthew Henry's Commentary on Deuteronomy 18:9-22

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.
