Sorcery
Scripture treats the magical arts as a single forbidden territory with many entrances. Divination, witchcraft, the consultation of spiritists and wizards, the interpretation of omens, the casting of spells, the inquiry of the dead, the reading of livers and of stars — Yahweh's law collects them under one verdict and his prophets refuse them one ruling. The umbrella runs from the sacred scholars of Egypt through the witch of En-dor and the Chaldean court of Babylon to the false prophet of the Apocalypse, and the canonical voice toward them runs in one direction: their signs are lying wonders, their counsel is vain, and the people of Yahweh are not allowed to do as the nations do.
The Mosaic Prohibition
The covenant catalogue in Deuteronomy 18 is the central ban. Israel is told that "when you come into the land which Yahweh your God gives you, you will not learn to follow the disgusting behaviors of those nations" (Deut 18:9). The list that follows is comprehensive: "There will not be found with you anyone who makes his son or his daughter to pass through the fire, one telling the future, one interpreting omens, or one who uses magic, or a sorcerer, or one casting spells, or one requesting a spirit, or a wizard, or one inquiring of the dead" (Deut 18:10-11). The verdict is unconditional — "For whoever does these things is disgusting to Yahweh: and because of these disgusting things Yahweh your God drives them out from before you" (Deut 18:12) — followed by the positive antithesis, "You will be perfect with Yahweh your God" (Deut 18:13). The contrast with the nations is then named directly: "For these nations that you will dispossess, listen to psychics and fortune-tellers; but as for you, Yahweh your God has not allowed you to do so" (Deut 18:14).
The Holiness Code adds the same boundary in different words. "You⁺ will not eat anything with the blood: neither will you⁺ use magic, nor interpret omens" (Lev 19:26). "Do⁺ not turn to the spiritists or to the wizards; do not seek them out, to be defiled by them: I am Yahweh your⁺ God" (Lev 19:31). "And the soul who turns to the spiritists or the wizards, to go whoring after them, I will even set my face against that soul, and will cut him off from among his people" (Lev 20:6). The penal sanction is sharp on both sides of the practice: against the practitioner himself, "You will not allow a witch to live" (Ex 22:18); against the medium, "And a man or a woman among them, who is a spiritist or a wizard, will surely be put to death: they will stone them with stones; their blood will be on them" (Lev 20:27).
The Sacred Scholars of Egypt
The opening contest of the Exodus is fought against a guild. When Moses confronts Pharaoh, "Pharaoh also called for the wise men and the sorcerers: and the sacred scholars of Egypt also did in like manner with their witchcraft" (Ex 7:11). Their imitation runs through three of the early plagues — the rod-to-serpent and the bloodied river ("the sacred scholars of Egypt did in like manner with their magic," Ex 7:22), and the frogs ("the sacred scholars did in like manner with their magic, and brought up frogs on the land of Egypt," Ex 8:7). The mimicry breaks at the gnats. "Then the sacred scholars said to Pharaoh, This is the finger of God: and Pharaoh's heart was hardened, and he didn't listen to them; as Yahweh had spoken" (Ex 8:19). By the boils the contest is over altogether — "And the sacred scholars could not stand before Moses because of the boils; for the boils were on the sacred scholars, and on all the Egyptians" (Ex 9:11). The same scholarly caste appears earlier in Genesis at Pharaoh's court, where "I told it to the sacred scholars; but there was none who could declare it to me" (Gen 41:24); and Joseph speaks in their idiom in his own deception of his brothers — "a man such as I can indeed use magic [to find out]" (Gen 44:15).
Isaiah turns this Egyptian wisdom on itself. "And the spirit of Egypt will fail in the midst of it; and I will destroy its counsel: and they will seek to the idols, and to the charmers, and to the spiritists, and to the wizards" (Isa 19:3). "The princes of Zoan are completely foolish; the counsel of the wisest counselors of Pharaoh has become brutish" (Isa 19:11). "Where then are your wise men? And let them tell you now if they know what Yahweh of hosts has purposed concerning Egypt" (Isa 19:12).
Israel Going Whoring After Spirits
The narrative of the kings is a long record of the prohibition being broken. Saul, having "rejected the word of Yahweh" through the sin of fortune-telling (1 Sam 15:23), seeks out at the end "a woman who is mistress of a spirit" (1 Sam 28:7). The summoning is requested in plain necromantic terms: "Then the woman said, Whom shall I bring up to you? And he said, Bring me up Samuel" (1 Sam 28:11). The oracle that follows seals Saul's verdict — Samuel asks "Why have you disquieted me, to bring me up?" (1 Sam 28:15), and Yahweh's word through him is that the kingdom is given to David and that "tomorrow you and your sons will be with me" (1 Sam 28:19). The Chronicler reads Saul's death through the same lens: "So Saul died for his trespass which he committed against Yahweh, because of the word of Yahweh, which he did not keep; and also for asking counsel of a spiritist, to inquire" (1 Chr 10:13).
The northern kingdom imports the same arts on a larger scale. Israel "caused their sons and their daughters to pass through the fire, and told the future and used magic" until Yahweh removed them (2 Kgs 17:17). Of Jezebel's reign Jehu says, "What peace, so long as the whoring of your mother Jezebel and her witchcrafts are so many?" (2 Kgs 9:22). In Judah, Manasseh "made his son to pass through the fire, and interpreted omens, and used magic, and dealt with spiritists and with wizards: he wrought much evil in the sight of Yahweh, to provoke him to anger" (2 Kgs 21:6); the chronicler's parallel adds witchcraft to the list (2 Chr 33:6). Josiah's reform reverses the catalogue point for point: "Moreover the spiritists, and the wizards, and the talismans, and the idols, and all the detestable things that were seen in the land of Judah and in Jerusalem, Josiah put away, that he might confirm the words of the law" (2 Kgs 23:24).
Even the Philistines turn to fortune-tellers when the ark is among them ("the Philistines called for the priests and the fortune-tellers, saying, What shall we do with the ark of Yahweh?" — 1 Sam 6:2). Moab and Midian come to Balaam "with the rewards of fortune-telling in their hand" (Num 22:7). Hosea names a debased rhabdomancy at home: "My people ask counsel at their stock, and their staff declares to them; for the spirit of whoring has caused them to err" (Hos 4:12). Isaiah locates the same contagion in Judah: "they are filled [with customs] from the east, and [are] omen interpreters like the Philistines" (Isa 2:6).
Babylon and the Court Magicians
Babylon is the great showcase city for the divinatory arts and, in the prophets, the great anti-type. Nebuchadnezzar's siege divination is described in detail: "the king of Babylon stood at the parting of the way, at the head of the two ways, to tell his fortune: he shook the arrows to and fro, he consulted the talismans, he looked in the liver" (Ezek 21:21). The reading falls on Jerusalem (Ezek 21:22). Daniel's portrait of the same court keeps the technical vocabulary: "Then the king commanded to call the sacred scholars, and the psychics, and the sorcerers, and the Chaldeans, to tell the king his dreams" (Dan 2:2). Their answer is itself the indictment: "There is not a man on the earth that can show the king's matter, since no king, lord, or ruler, has asked such a thing of any sacred scholar, or psychic, or Chaldean" (Dan 2:10). Daniel says it more bluntly: "The secret which the king has demanded can neither wise men, psychics, sacred scholars, nor astrologers, show to the king" (Dan 2:27). The pattern repeats under Nebuchadnezzar's later dream — "Then the sacred scholars, the psychics, the Chaldeans, and the astrologers came in; and I told the dream before them; but they did not make known to me its interpretation" (Dan 4:7) — and on the night of Belshazzar's feast: "The king cried aloud to bring in the psychics, the Chaldeans, and the astrologers" (Dan 5:7). Belshazzar himself confesses the failure: "the wise men, the psychics, have been brought in before me, that they should read this writing, and make known to me its interpretation; but they could not show the interpretation of the thing" (Dan 5:15).
Isaiah addresses Babylon directly. "But these two things will come to you in a moment in one day, the loss of children, and widowhood; in their full measure they will come upon you, in the multitude of your witchcraft, and the great abundance of your magic words" (Isa 47:9). "Stand now with your magic words, and with the multitude of your witchcraft, in which you have labored from your youth; perhaps you will be able to profit, perhaps you may prevail" (Isa 47:12). "You are wearied in the multitude of your counsels: let the astrologers stand up now and save you, those observing the stars for determining your horoscopes" (Isa 47:13). Jeremiah extends the warning to Judah's diplomats: "don't listen to your⁺ prophets, or to your⁺ fortune-tellers, or to your⁺ dreamers, or to your⁺ psychics, or to your⁺ sorcerers, who speak to you⁺, saying, You⁺ will not serve the king of Babylon" (Jer 27:9). And astrology in particular is dismissed in a single breath: "Don't learn the way of the nations, and don't be dismayed at the signs of heaven; for the nations are dismayed at them" (Jer 10:2).
En-dor and the Inquiry of the Dead
Necromancy gets its sharpest treatment in Isaiah. "And when they will say to you⁺, Seek to the spiritists and to the wizards, who chirp and who mutter: should not a people seek to their God? On behalf of the living [should they seek] to the dead?" (Isa 8:19). The judgment that falls on Jerusalem is described in the same idiom as a medium's voice: "your voice will be as a spirit out of the ground, and your speech will whisper out of the dust" (Isa 29:4). The picture overlaps with the En-dor scene — "I see a god coming up out of the earth" (1 Sam 28:13) — and the prohibition against "one inquiring of the dead" in Deut 18:11 names the underlying practice. The book of Ben Sira renders the canonical verdict on the whole class of techniques in one line: "Divinations, and soothsayings, and dreams are vain, As you hope so does your heart see" (Sir 34:5).
The Vainness of the Diviner
The prophets' running argument against the magical arts is that they do not work. Yahweh "frustrates the signs of the liars, and makes fortune-tellers insane; who turns wise men backward, and makes their knowledge foolish" (Isa 44:25). "For the talismans have spoken vanity, and the fortune-tellers have seen a lie; and they have told false dreams, they comfort in vain" (Zech 10:2). The judgment on Israel's professional diviner-prophets is that they will be silenced: "Therefore it will be night to you⁺, that you⁺ will have no vision; and it will be dark to you⁺, that you⁺ will not have fortune-telling . . . And the seers will be put to shame, and the fortune-tellers confounded; yes, they will all cover their lips; for there is no answer of God" (Mic 3:6-7). Micah promises a covenant cleansing: "And I will cut off sorcerers out of your hand; and you will have no psychics" (Mic 5:12). Ezekiel speaks in the same key: "I will make this proverb to cease . . . For there will be no more any false vision nor flattering psychic readings inside the house of Israel" (Ezek 12:23-24); "you⁺ will no more see false visions, nor tell any fortunes" (Ezek 13:23).
The prophets who speak in Yahweh's name without being sent are absorbed into the same category. "And my hand will be against the prophets who see false visions, and who tell lying fortunes: they will not be in the council of my people . . . neither will they enter into the land of Israel" (Ezek 13:9). "And her prophets have daubed for them with untempered [mortar], seeing false visions, and telling them lying fortunes, saying, Thus says the Sovereign Yahweh, when Yahweh has not spoken" (Ezek 22:28). Ezekiel applies the same charge against Ammon — "while they see for you false visions, while they tell you a lying fortune" (Ezek 21:29).
Nineveh and Her Witchcrafts
Nineveh is treated as Babylon's twin: "the well-favored whore, the mistress of witchcrafts, that sells nations through her whorings, and families through her witchcrafts" (Nah 3:4). The judgment is direct — "Look, I am against you, says Yahweh of hosts" (Nah 3:5).
Sorcery in the New Covenant
The umbrella does not narrow in the New Testament; it is reframed. Sorcery stands in the apostolic vice-list as one of "the works of the flesh" — "idolatry, witchcraft, enmities, strife, jealousy, wraths, factions, divisions, parties" (Gal 5:20). The eschatological lawless one comes "according to the working of Satan with all power and signs and lying wonders" (2 Thess 2:9). Jesus warns that "there will arise false Christs, and false prophets, and will show great signs and wonders; so as to lead astray, if possible, even the elect" (Matt 24:24). The Apocalypse picks up the same vocabulary for the beast's prophet, who "does great signs, that he should even make fire to come down out of heaven on the earth in the sight of men" (Rev 13:13), and for the demonic spirits "working signs" before the kings of the world (Rev 16:14). The false prophet's signs deceive those who took the mark (Rev 19:20). Babylon falls because "with your witchcraft were all the nations deceived" (Rev 18:23). And the final separation places sorcerers outside the city: "for the fearful, and unbelieving, and those who have become disgusting, and murderers, and whores, and sorcerers, and idolaters, and all liars, their part [will be] in the lake that burns with fire and brimstone" (Rev 21:8).
The Verdict in One Sentence
Malachi gathers the canonical voice into a single judicial line: "And I will come near to you⁺ to judgment; and [my Speech] will be a swift witness against the sorcerers, and against the adulterers, and against the false swearers, and against those who unjustly reduce the wages of the hired worker, the widow, and the fatherless, and who turn aside the sojourner [from his right], and do not fear me, says Yahweh of hosts" (Mal 3:5).
