I will destroy your witchcraft and you will no longer cast spells.

all because of the wanton lust of a prostitute, alluring, the mistress of sorceries, who enslaved nations by her prostitution and peoples by her witchcraft.

Galatians 5:19-21

19 The acts of the flesh are obvious: sexual immorality, impurity and debauchery; 20 idolatry and witchcraft; hatred, discord, jealousy, fits of rage, selfish ambition, dissensions, factions 21 and envy; drunkenness, orgies, and the like. I warn you, as I did before, that those who live like this will not inherit the kingdom of God.

Jamieson-Fausset-Brown Bible Commentary(on Dueteronomy 18:10)

De 18:9-14. The Abominations of the Nations Are to Be Avoided.

9-14. thou shalt not learn to do after the abominations of those nations—(See on [152]Le 18:21; [153]Le 19:26; [154]Le 19:31; [155]Le 20:4). In spite of this express command, the people of Canaan, especially the Philistines, were a constant snare and stumbling block to the Israelites, on account of their divinations and superstitious practices.

Matthew Poole's Commentary(on Dueteronomy 18:10)

To pass through the fire; either by a superstitious lustration or purgation, or by a cruel sacrificing of them. See Leviticus 18:21 2 Kings 17:31 23:10 2 Chronicles 28:3 Psalm 106:37 Jeremiah 7:31 19:5 Ezekiel 16:20,21 Eze 23:37-39.

That useth divination, i.e. foretelleth things secret or to come, Micah 3:11, by unlawful arts and practices.

An observer of times; superstitiously pronouncing some days good and lucky, and others unlucky, for such or such actions. Or,

an observer of the clouds or heavens, i.e. one that divineth by the motions of the clouds, by the stars, or by the flying or chattering of birds, all which heathens used to observe.

An enchanter, or, a conjecturer, that discovers hidden things by a superstitious use of words or ceremonies, by observation of water or smoke, or any contingencies, as the meeting of a hare, &c. See Poole "Leviticus 19:26".

A witch; one that is in covenant with the devil, and by his help deludes their senses, or hurts their persons. See Exodus 7:11 22:18.

Pulpit Commentary (on Micah 5:12)

Verse 12. - Witchcrafts. Magic and sorcery, which were much practised in Syria and Palestine, as in Chaldea, the literature of which country consists in great part of spells and charms. It is to the belief in the efficacy of such incantations that we owe the episode of Balak and Balaam (Numbers 22-24.), and the enactments in the Law; e.g. Deuteronomy 18:10, etc. (comp. Isaiah 2:6; Isaiah 47:12). Septuagint, t? f??µa?? s??, "thy poisons;" Vulgate, maleficia. Soothsayers; properly, cloud diviners, or storm makers; either persons who professed to divine by means of the shape and colour of clouds, or, as the old Scandinavian witches, charlatans who assumed the power of musing and directing storms. Cheyne compares the common name of sorcerers among savages, "rain makers."

Cambridge Bible for Schools and Colleges (on Nahum 3:4)

4. multitude of the whoredoms] The phrase “whoredom” when used of Israel meant, first, infidelity to Jehovah, God of Israel, by serving other gods; then it was applied to alliances and political intercourse with other nations, partly because such trust in other nations betrayed distrust of Jehovah and falsehood to Him, and partly because the political influence of powerful states like Assyria and Babylon was naturally followed by an invasion of their customs and religious ideas, as was seen in the decline of the kingdom of Judah; and finally, mere political or commercial intercourse of one nation with another was called “whoredom,” even when the religious idea was not involved. In this weaker sense the term seems employed here, viz. of political intercourse; in Isaiah 23:17 it is used of commercial intercourse. Comp. Ezekiel 16:26-29; Ezekiel 23:40 seq.

the wellfavoured harlot] “Wellfavoured” means beautiful, though the phrase has perhaps ceased to be usual in common language; in the northern dialect “weel fa’art” is still common for good-looking. Beauty or charm is a point in the harlot; the reference perhaps is less to the splendour and riches of the imperial city than to the dazzling prestige of the empire, which fascinated weaker states and rulers, as for example in the case of Ahaz.
