What Is a Medium in the Bible? Leviticus 19:31 Explained
Short answer: In Scripture a medium is someone who claims to make contact with the dead or to channel hidden spiritual knowledge through a spirit other than God. Leviticus 19:31 says, "Don't turn to those who are mediums, nor to the wizards. Don't seek them out, to be defiled by them. I am Yahweh your God." The command is not merely about a profession; it is about where a person goes for guidance, comfort, and access to the unseen. God treats that turning as spiritual unfaithfulness, which is why Leviticus 20:6 describes it as playing the prostitute after them. The Bible never denies that such practitioners exist or that they can seem to deliver results. It denies that God's people may seek them. The issue is allegiance and trust. A medium is therefore defined less by technique and more by the substitute it offers for living fellowship with God.
What the Hebrew terms behind the word medium actually describe
The Hebrew word usually translated as medium is tied to the idea of a familiar spirit, a spirit attached to a practitioner. The word often rendered wizards refers to those who claim secret knowledge. Together they describe a class of specialists in ancient Canaan who offered access to the dead and to hidden information. Deuteronomy 18:9-14 places them among the abominations of the surrounding nations and tells Israel not to learn to imitate them. So the category is not vague. It names real services people offered for a price in the ancient world.
This matters because modern readers often picture only a séance or a crystal ball. The biblical category is broader. Anyone who offers a practiced route to the spirit world apart from Yahweh fits the description, whether the method is an incantation, a ritual, or a familiar spirit speaking through a person. Acts 16:16-18 shows the pattern continuing in the New Testament: a girl with a spirit of divination brought her masters much gain by fortune telling.
Notice the combination of spiritual power and commercial gain in that account. The medium is not merely a private eccentric. The practitioner is a service provider, and the spirit is a source of income. That is one reason Scripture treats the whole system as rival worship rather than harmless curiosity. Something other than God is being trusted, paid, and followed.
Why Leviticus 19:31 attaches the command to the character of God
Leviticus 19:31 does not stop at the prohibition. It ends with a self-identification: "I am Yahweh your God." The command is grounded in covenant relationship. Israel had been rescued by Yahweh and belonged to him. Turning to a medium was therefore not a neutral self-help choice but a step away from the one who had redeemed them. The verse also says the seeker is defiled by the contact, which means the harm runs in both directions, to the practitioner and to the one who seeks.
That closing phrase also supplies the positive alternative. If Yahweh is their God, then Yahweh is the one to be consulted. This is the logic Isaiah 8:19-20 presses home when it asks, should a people consult the dead on behalf of the living? The implied answer is no. The living have a living God. The question is framed as obvious precisely because it should be obvious to people who know Yahweh.
So the prohibition is not arbitrary. It is relational. The command against mediums is one application of the first commandment. Whatever a person runs to for guidance and reassurance when God seems silent is functionally a god. Leviticus 19:31 names one such rival and rules it out.
The seriousness of the sin in Leviticus 20:6
Leviticus 20:6 raises the stakes: "The person that turns to those who are mediums and wizards, to play the prostitute after them, I will even set my face against that person, and will cut him off from among his people." The language of prostitution is covenant language. It describes a people who belong to God giving their devotion to another. The consequence is being cut off, which in Israel meant removal from the covenant community.
This is stronger than a general warning about bad influences. It is a description of betrayal. Yet it also reveals something about God's character, because he does not merely ignore the offense. He sets his face against it. A God who set his face against nothing would not be loving; he would be indifferent to the destruction of the people he redeemed. The severity here is the severity of a faithful husband toward a rival that is ruining his wife.
Readers should also notice that the verse does not describe a single moment of weakness as the same thing as settled pursuit. The Hebrew image is of going after them, playing the prostitute after them. It depicts a direction of life, not merely a stumble. Scripture consistently distinguishes between a person who is being drawn and a person who has given themselves over.
Saul and the medium at Endor: what the story does and does not show
First Samuel 28 records the most famous consultation with a medium in the Bible. Saul had removed mediums from the land, but when God did not answer him by dreams, by Urim, or by prophets, he asked his servants to find a woman with a familiar spirit so he could inquire of her. The narrator is careful to note the sequence. Saul sought Yahweh first, and when no answer came, he turned elsewhere.
The story is a study in how a person arrives at a forbidden door. It is not that Saul was ignorant of the law. He had enforced it. It is that unanswered prayer plus fear plus an army on the horizon produced a heart willing to violate what he knew. The medium at Endor is therefore not presented as a solution but as a symptom. His visit is the visible evidence of a relationship that had already broken down.
What happened in that room has been interpreted differently by faithful readers. Some hold that God genuinely permitted Samuel to appear and deliver a final word. Others hold that the woman's familiar spirit produced the likeness and that the message was a counterfeit. The text reports the event without resolving every mechanism. What the text does establish is that Saul's turning to her was judged, and that he died the next day. The passage never invites imitation.
Isaiah 8:19-20 and the contrast between consulting the dead and trusting God
Isaiah 8:19-20 sets up a sharp contrast. When people say to consult with those who have familiar spirits and with the wizards, who chirp and who mutter, the prophet responds with a question: shouldn't a people consult with their God? Should they consult the dead on behalf of the living? The mockery in the phrase chirp and mutter is deliberate. What the nations treat as profound is, from Isaiah's vantage point, mere noise.
The verse also gives a test. Instruction and testimony are the standard. If what is said does not match that word, there is no light in it. This is a useful practical rule even where the phenomena are unfamiliar. The question is not only whether a practice is forbidden but whether the guidance it produces conforms to God's revealed word. Anything that must be checked against Scripture and fails the check is not a source of light.
Isaiah's contrast also exposes the underlying absurdity. The dead are consulted on behalf of the living. But the living have the living God, who has spoken. Israel's problem was never a lack of access. It was a lack of willingness to wait on the access they already had.
What the New Testament adds through the girl at Philippi
Acts 16:16-18 records Paul meeting a slave girl with a spirit of divination. She followed Paul and his companions for days, announcing that they were servants of the Most High God. What she said was accurate. Paul still cast the spirit out. This is instructive. The problem was not that her statements were false but that the power behind them was not from God. Accuracy alone does not sanctify a source.
The account also shows the collision between the gospel and the spirit world. The fortune telling was profitable, and when the spirit left, so did the income. The masters of the girl were not outraged on theological grounds; they were outraged because their hope of profit was gone. The narrative quietly reveals what the trade was really serving. It served money first and spiritual curiosity second.
For readers today, this passage clarifies that the New Testament does not treat divination as a harmless relic of the ancient world. It treats it as a real spiritual power that the gospel confronts and defeats. The same Lord who forbade Israel to seek mediums is the Lord who silences a spirit of divination in Philippi.
How to think about mediums today without panic or compromise
The clearest boundary Scripture gives is this: God's people do not seek out mediums, and they do not treat them as a source of guidance, comfort, or contact with the dead. This does not require fear of the practitioners. It requires a settled loyalty. The prohibition in Leviticus 19:31 is directed at the seeker, not only at the medium, which means the command addresses ordinary people in ordinary grief and uncertainty.
At the same time, the Bible's rejection of mediums is not a rejection of all comfort concerning the dead. Scripture speaks of being absent from the body and present with the Lord, of the resurrection, and of the reunion of God's people. Grief is real, and God does not scold it. What he forbids is seeking the dead through forbidden means. The pastoral alternative is not coldness but a different hope, rooted in resurrection rather than in séance. Faithful Christians have differed on many details in this area, including how to interpret unusual experiences, but the command itself is not ambiguous.
Practically, this means a Christian can decline invitations to consult mediums, tarot readers, or similar practitioners without hostility, and can gently explain why. It also means churches should make room for grief, since the pull toward forbidden sources is strongest where grief has no honest outlet. A community that speaks openly about death and resurrection removes some of the pressure that drives people to other doors.
Biblical fidelity check
What Leviticus 19:31 and its parallel passages establish is a clear command: God's covenant people are not to turn to mediums or wizards or seek them out. The passages also establish the reason, which is the exclusive claim of Yahweh, and the seriousness, which is covenant betrayal leading to being cut off. Deuteronomy 18:9-14, Leviticus 20:6, Isaiah 8:19-20, and Acts 16:16-18 all reinforce the same boundary in different settings across the canon.
What these passages do not establish is a detailed theory of how every occult phenomenon works, whether every reported experience is genuine, or what the precise mechanism was in the account at Endor. The Bible does not satisfy every curiosity, and it does not authorize God's people to investigate forbidden practices in order to understand them better. A common misreading treats the prohibition as superstition that a modern person has outgrown, as if the command were about ancient ignorance rather than about loyalty to God. That reading fails because the New Testament, written in a world as sophisticated as any, treats the same powers as real and confronts them directly. Another misreading treats the command as a reason to fear mediums or to become preoccupied with them. Scripture commands avoidance, not obsession.
Other passages that speak to Leviticus 19:31
Several related studies help place this command in the wider story of Scripture. The prophets repeatedly call God's people to trust the God who speaks rather than the powers that mutter, which is the theme of Isaiah 40:31 Meaning: Wings Like Eagles and What does Isaiah 41:10 mean? The rise of Saul, who enforced the law against mediums and then consulted one, is best understood against the background of his whole reign, sketched in 1 Samuel 10: Samuel Anoints Saul and Signs Confirm. And the broader account of Israel's leadership, including the transition that made Saul king, is traced in 1 Samuel 1: Hannah's Prayer and Samuel's Birth. Together these passages show that the question of mediums is finally a question about whom God's people will trust.
Frequently asked questions
What exactly is a medium according to the Bible?
A medium in Scripture is a person who claims to contact the dead or to channel hidden spiritual knowledge through a familiar spirit. The Hebrew terms describe a recognized class of practitioners in the ancient world, often paired with wizards or those who claim secret knowledge. Deuteronomy 18:9-14 lists them among the practices of the surrounding nations that Israel must not imitate. The defining feature is not a technique but a claimed route to the spirit world apart from Yahweh, offered as a service to those who seek it.
Why does God forbid seeking mediums in Leviticus 19:31?
The verse grounds the command in covenant identity. Leviticus 19:31 says, "Don't turn to those who are mediums, nor to the wizards. Don't seek them out, to be defiled by them. I am Yahweh your God." Since Yahweh is their God, seeking another source of guidance is a rival allegiance. Leviticus 20:6 describes it as playing the prostitute after them, which is the language of betrayal. The command protects the relationship more than it restricts curiosity.
Was the medium at Endor actually speaking to Samuel?
Faithful Christians have read 1 Samuel 28 differently. Some hold that God genuinely permitted Samuel to appear and deliver a final word of judgment. Others hold that the woman's familiar spirit produced a counterfeit likeness. The text reports the event without explaining the mechanism, and it does not commend Saul's action. What the passage does make clear is that Saul's turning to her followed his own refusal to wait on God, and that he died the next day.
