Familiar Spirits

A familiar spirit, in older English Bible translations, is a spirit attached to a person and consulted for hidden knowledge — ordinarily the spirit of a dead person — and, by extension, the medium who deals with such a spirit. The Hebrew term behind the phrase is 'ob, which can denote the spirit itself, the practitioner, or the practice, and it is usually paired with yidde'oni, rendered “wizard” or “knowing one” (Leviticus 19:31; Deuteronomy 18:11). Linguistically, the English word “familiar” here carries its older sense of a close attendant or household acquaintance, not the modern sense of “well known”; many modern versions render 'ob as “medium” and yidde'oni as “necromancer,” as the World English Bible does at Deuteronomy 18:11. The etymology of 'ob is uncertain, and the common suggestion that it derives from a root meaning “to return” (the dead returning) is scholarly inference rather than established fact.

What Scripture says about the practice is uniformly prohibitive. Leviticus 19:31 reads, “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 text frames the offense as spiritual infidelity rather than mere superstition: Leviticus 20:6 describes the one who turns to mediums and wizards “to play the prostitute after them,” and Leviticus 20:27 assigns the death penalty within Israel’s civil order — “They shall be stoned with stones. Their blood shall be upon themselves.” Deuteronomy 18:10–11 lists “someone who consults with a familiar spirit” among the practices of the peoples Israel is displacing, alongside divination, fortune-telling, sorcery, and the burning of children. In each case the stated ground of the prohibition is Israel’s exclusive relationship with Yahweh.

The narrative books treat the matter as a real contest of loyalties, not simply as fraud. First Samuel 28:3 records that Saul “had sent away those who had familiar spirits and the wizards out of the land,” yet when “Yahweh didn’t answer him by dreams, by Urim, or by prophets” (1 Samuel 28:6), he seeks “a woman who has a familiar spirit” at Endor (1 Samuel 28:7) and asks her to bring up Samuel. The Chronicler’s verdict is that Saul died “because he asked counsel of one who had a familiar spirit, to inquire” (1 Chronicles 10:13). Isaiah 8:19 appeals to ordinary sense — “Shouldn’t a people consult with their God? Should they consult the dead on behalf of the living?” — and Isaiah 19:3 lists mediums and wizards among the refuges Egypt will find useless when God judges it.

Christian traditions differ on several points. Nearly all agree the texts forbid consulting spirits or mediums, but they divide over what is actually happening in 1 Samuel 28 — whether Samuel himself appeared, whether a demonic power impersonated him, or whether the account reports a deception — and that disagreement is old and unresolved. Traditions that take the spirit world as directly active, including Catholic deliverance ministry and much Pentecostal and charismatic teaching, read the passages as warnings about real and dangerous powers, while some Reformed and cessationist readings stress that divination is rebuked as futile rather than powerful. Many traditions hold that the Mosaic death penalty belonged to Israel’s theocratic order and does not transfer to church or state, while others appeal to it as showing the gravity of the sin. More liberal readings treat the prohibitions as polemic against ancient Near Eastern religious practice, so that the enduring offense is seeking guidance apart from God rather than any metaphysical claim about the dead.
