The source of this mitzvah is the verse, “לֹא תְנַחֲשׁוּ” — “Do not practice divination” or “Do not be superstitious” (Leviticus 19:26). Chazal and the halachic tradition explain this as the prohibition of ניחוש — arranging conduct around omens and imagined signs, such as saying: “Since this happened, I will do this,” or “Because that occurred, this matter will succeed or fail.” The Torah forbids giving spiritual authority to arbitrary signals.

On the halachic plane, the issur is not limited to formal magical ritual. It includes ordinary-looking patterns of behavior in which a person lets a sign, coincidence, phrase, animal, event, or sequence determine his action in a way the Torah never authorized. The problem is not prudence, experience, or ordinary caution. The problem begins when a person surrenders decision-making to superstition instead of Torah, wisdom, and trust in Hashem.

Conceptually, this mitzvah protects the mind from false structure. Superstition creates a world in which life is governed by symbolic clues that must be decoded rather than by moral responsibility before Hashem. It tempts a person to replace avodah with pattern-reading and to trade emunah for imagined control. The Torah therefore rejects superstition not only because it is mistaken, but because it trains the soul to seek meaning and guidance in the wrong places.

Rambam

• Source: Sefer HaMitzvos, Lo Taaseh 32; Mishneh Torah, Hilchos Avodas Kochavim 11
• Rambam defines מנחש as one who acts based on omens, such as saying that because a certain event occurred, he will act or refrain from acting in a certain way. His presentation is crucial because he shows that superstition is not merely an odd belief. It becomes forbidden when a person organizes conduct around the sign itself, granting it authority that belongs only to Torah, wisdom, and Hashem.

Sefer HaChinuch

• Source: Sefer HaChinuch, mitzvah of לא תנחשו
• Sefer HaChinuch explains that the Torah distances Israel from emptiness and falsehood, training the Jew to place trust only in Hashem. His contribution is deeply formative. Superstition weakens the soul by making it dependent on arbitrary signals rather than on truth, judgment, and Divine service.

Gemara

• Source: Sanhedrin 65b
• The Gemara discusses the category of ניחוש and gives examples of conduct shaped by omens and signs. This sugya is foundational because it makes clear that the Torah is forbidding a real behavioral system, not merely an abstract bad attitude.

Gemara

• Source: Chullin 95b
• Chazal discuss forms of sign-based conduct and the boundaries between prohibited superstition and ordinary human discernment. The sugya is important because it sharpens the line: the Torah does not forbid intelligence or caution, but it does forbid turning signs into governing authorities.

Gemara

• Source: Avodah Zarah 11a
• The Gemara links superstitious and omen-based practices to the surrounding patterns of gentile culture and worship. Its contribution is that superstition is not only a private error in judgment. It belongs to a broader world of foreign dependence and distorted meaning. By forbidding such practices, the Torah protects Israel from being drawn into a mindset in which signs, customs, and fears replace direct trust in Hashem.

Sifra

• Source: Sifra to Leviticus 19:26
• The Sifra reads לא תנחשו as a direct prohibition against omen-based behavior. Its contribution is textual precision. The Torah is not condemning a general mood, but a specific pattern of acting under the imagined power of signs.

Midrash

• Source: Midrashic teachings on תמימות — wholeness with Hashem
• Midrashic teachings repeatedly direct a Jew toward simple, whole reliance on Hashem rather than toward hidden manipulative systems. Within that framework, superstition appears as a fracture in trust, where the person seeks reassurance outside the path Torah gave him.

Rashi

• Source: Rashi to Leviticus 19:26
• Rashi explains the prohibition through familiar examples of omen-taking, where a person says that because something happened, his course of action is now decided. His contribution is peshat clarity. Superstition is not mysterious. It appears in simple decisions distorted by imagined signs.

Ramban

• Source: Ramban to Leviticus 19:26
• Ramban places ניחוש among the Torah’s prohibitions against occult and manipulative systems. His nuance is that the issue is not only incorrect belief. It is the deeper movement of turning away from direct dependence on Hashem toward lower, false channels of guidance.

Ibn Ezra

• Source: Ibn Ezra to Leviticus 19:26
• Ibn Ezra keeps the prohibition direct and practical. His contribution is straightforwardness: the Torah forbids acting on omens and arbitrary signs as though they reveal what one must do.

Sforno

• Source: Sforno to Leviticus 19:26
• Sforno explains that these practices pull the person away from clean reliance on Hashem. His nuance sharpens the inner issue. Superstition is not harmless symbolism. It quietly retrains the heart toward misplaced dependence.

Rabbeinu Bachya

• Source: Rabbeinu Bachya to Leviticus 19:26
• Rabbeinu Bachya underscores that the Torah wants Israel to live with wholeness before Hashem and not under the shadow of invented signs. His contribution is emotional and spiritual: superstition weakens inner composure by teaching a person to fear patterns instead of serving Hashem.

Abarbanel

• Source: Abarbanel to Leviticus 19:26
• Abarbanel situates this prohibition within the Torah’s larger rejection of pagan consciousness. His contribution is structural. Superstition is one form of a broader worldview in which man seeks control through false signals rather than covenantal obedience.

Kuzari

• Source: Kuzari, on authentic Divine guidance versus humanly invented channels
• The Kuzari’s broader framework helps explain why superstition is spiritually degrading. Torah directs the Jew toward real revelation, prophecy, mitzvos, and providence. Superstition replaces these with lower, unstable, man-made systems of meaning.

Maharal

• Source: Maharal, on order, providence, and false causality
• Maharal’s conceptual framework helps show that superstition corrupts a person’s grasp of reality by confusing random association with meaningful order. Instead of seeing the world under Hashem’s rule, the superstitious mind invents connections that distort both reason and faith.

Ramban

• Source: Ramban to Leviticus 19:26
• On the conceptual plane, Ramban helps show that the Torah’s objection is not simply to error, but to dependence. The Jew may not live as though signs and omens mediate his path. He is meant to belong directly to Hashem.

Abarbanel

• Source: Abarbanel to Leviticus 19:26
• Abarbanel’s system-level contribution is that superstition belongs to a world where fear, uncertainty, and hidden control replace covenantal trust. Torah dismantles that world and restores the person to responsibility, prayer, and obedience.

Shulchan Aruch

• Source: Yoreh De’ah 179
• The Shulchan Aruch codifies the laws of forbidden omen-based conduct and bars acting on superstitious signs. In practical terms, a Jew may not let an arbitrary occurrence govern whether he proceeds with a matter.

Rema

• Source: Yoreh De’ah 179
• The Rema preserves the distinction between prohibited superstition and normal prudence. His role here is important because Torah does not forbid thoughtful caution, planning, or sensible judgment. It forbids assigning ruling force to omens.

Nosei Keilim

• Source: Commentarial tradition on Yoreh De’ah 179 and Hilchos Avodas Kochavim
• The halachic tradition sharpens that the issur emerges when the sign itself becomes decisive. That is the practical core of the mitzvah: not noticing something, but submitting to it as though it were an authorized guide.

Chasam Sofer

• Source: Teachings on תמימות with Hashem and rejection of false systems
• Chasam Sofer deepens the prohibition by showing that Torah life cannot be shared with hidden private superstitions. Once a person grants those patterns authority, his trust in Hashem has already been weakened.

Netziv

• Source: HaEmek Davar to Leviticus 19:26
• Netziv expands the mitzvah into covenantal identity. Israel is not meant to live by symbolic fear or omen-reading, but by direct accountability to Hashem and His Torah.

Rav Shimshon Raphael Hirsch

• Source: Hirsch to Leviticus 19:26
• Hirsch explains that superstition enslaves the human being by placing him under irrational fear and invented necessity. His contribution is especially strong here: the Torah frees man from being ruled by signs so that he can live with moral dignity before Hashem.

Malbim

• Source: Malbim to Leviticus 19:26
• Malbim’s careful distinctions help clarify that superstition is not identical to every other forbidden occult category. His contribution strengthens the precision of the mitzvah by defining its unique mechanism: false guidance through omens.

Rav Kook

• Source: Writings on emunah, inner freedom, and direct reliance on Hashem
• Rav Kook broadens this mitzvah by showing that a deeper emunah frees the soul from fear-driven dependence on hidden patterns. The more a person lives before Hashem clearly, the less he needs superstitious structures to feel secure.

Meshech Chochmah

• Source: Meshech Chochmah to Leviticus 19:26
• Meshech Chochmah deepens the relation between this prohibition and the Torah’s broader struggle against pagan mentality. Superstition belongs to a world where man is intimidated by fragments of creation. Torah restores him to serving the Creator directly.

Baal Shem Tov

• Source: Teachings on hashgachah pratis and direct trust in Hashem
• The Baal Shem Tov’s inner contribution is that a Jew must live with awareness that Hashem Himself guides every detail of life. When that awareness is strong, superstition loses its emotional grip. The soul no longer needs invented signs to feel that life has meaning.

Tanya

• Source: Tanya, on emunah, Divine unity, and dependence on Hashem
• Tanya’s framework helps make this mitzvah inwardly alive. A person who knows that all existence depends continuously on Hashem has less room for fear of arbitrary signs. The prohibition thus protects inner clarity as much as outer conduct.

Sfas Emes

• Source: Sfas Emes on תמימות and direct life with Hashem
• Sfas Emes presents spiritual wholeness as the refusal to become scattered among secondary forces and symbolic dependencies. The inner avodah of this mitzvah is to live simply and directly with Hashem rather than through imagined codes.

Ramchal

• Source: Mesillas Yesharim and Derech Hashem
• Ramchal’s framework shows that refined avodah depends on clear thought and freedom from illusion. Superstition clouds both. It offers false order where Torah demands truth, and therefore the person seeking refinement must uproot dependence on it.

This mitzvah appears in the Torah’s larger cluster of prohibitions against divination, omen-reading, astrology, and other occult practices. Its background is therefore essential. The Torah is not merely rejecting a few strange habits. It is dismantling an entire way of seeing the world in which people seek control, reassurance, and hidden guidance through unauthorized signals. This broader Torah stance is echoed in Yeshayahu’s mockery of the astrologers and star-gazers of Bavel, who promise insight into what is coming but cannot save even themselves. The navi exposes the emptiness of celestial reliance and reinforces the Torah’s demand that Israel not build life on omens, stars, or hidden signs, but on trust in Hashem and obedience to His word. In the Rambam’s canonical count used by this guide, Mitzvah 60 — Not to be superstitious stands near the avodah zarah–adjacent prohibitions because superstition, even when it appears mild, trains the soul toward false dependence. The mitzvah protects not only behavior, but the structure of emunah itself. A Jew is meant to live with wisdom, responsibility, and trust in Hashem, not by fear of omens.
