This mitzvah forms a person who does not measure morality only by the final act, but by the kind of nearness he allows himself to create. It develops an inner clarity that not every feeling deserves expression, and not every form of closeness is innocent simply because it stops short of the most severe aveirah. A Torah life becomes more alert, more bounded, and more truthful at the point where desire first begins to seek form.

That awareness creates structure. A person begins to live with more seriousness around touch, social familiarity, and emotional atmosphere. Life becomes less driven by impulse and more ordered by yiras Shamayim — reverence for Heaven. What might otherwise be treated as casual becomes part of avodas Hashem — serving Hashem, because the body too is brought under Torah discipline.

Emotionally, this mitzvah can feel demanding because it asks a person to step back before the heart and body fully lean in. Yet that restraint is not emptiness. It builds dignity, self-command, and a cleaner inner world. On the communal level, it helps preserve trust, family integrity, and a culture in which kedushah is not an abstract word, but a lived boundary that protects people from being reduced to desire.

Rambam

• Source: Sefer HaMitzvos, Lo Taaseh on לא תקרבו לגלות ערוה; Mishneh Torah, Hilchos Issurei Biah 21:1.
• Rambam defines this mitzvah structurally as a prohibition on קריבה to arayos — prohibited women — through acts such as embracing, kissing, and similar physical closeness when done דרך תאוה — in a manner of desire. His formulation is important because it treats these acts not merely as safeguards around the main prohibition, but as a lav — an independent negative command rooted in the verse itself. The mitzvah therefore establishes a halachic category of forbidden nearness, not only a warning against eventual bi’ah — relations.

Sefer HaChinuch

• Source: Sefer HaChinuch, on the prohibition of לא תקרבו לגלות ערוה in Parshas Acharei Mos.
• Sefer HaChinuch presents the shoresh — root idea — as the Torah’s demand that a person distance himself from the avenues that awaken forbidden desire and lead to corruption. He frames the mitzvah as human formation: the Torah knows that the heart and body are drawn step by step, and therefore it trains a Jew to live with foresight rather than self-deception. The mitzvah shapes character by teaching restraint before collapse, and by making kedushah depend not only on what one finally does, but on what one allows himself to become comfortable with.

Sifra

• Source: Sifra, Acharei Mos, on לא תקרבו לגלות ערוה.
• The Sifra reads the verse as a prohibition on forms of approach that precede and lead into forbidden relations. Chazal thereby establish that the Torah did not speak only about the final act, but about the domain of conduct that constitutes entry into that act. The verse becomes a foundational source for understanding that the Torah legislates the border-zone of ervah, not only its endpoint.

Gemara

• Source: Shabbos 13a.
• The Gemara, in the context of a niddah — a menstruantly impure woman — treats the Torah’s warning of לא תקרבו as generating concrete distance, and Chazal add protective conduct so that familiarity does not slide into violation. The famous Chazal expression there reflects the Torah’s logic: one does not merely prohibit the vineyard; one tells the nazir — the abstainer — not to circle close to it. The sugya shows that where desire is powerful, Torah distance is itself a form of wisdom.

Gemara

• Source: Avodah Zarah 20b.
• This sugya broadens the field by stressing the seriousness of guarding the avenues of desire, including forms of looking and mental indulgence that feed physical wrongdoing. Chazal are teaching that illicit intimacy does not begin only in the body. It is often prepared by gaze, imagination, and cultivated interest. This deepens Mitzvah 175 by placing physical contact inside a larger Torah discipline of guardedness.

Gemara

• Source: Sanhedrin 75a.
• The Gemara’s refusal to permit even indirect erotic gratification in the face of overwhelming passion underscores the severity with which forbidden intimacy is treated. Chazal do not regard desire as a force that suspends the law. On the contrary, the sugya highlights that arayos belong to a realm where Torah insists that the person be ruled by holiness, not by emotional pressure.

Midrash

• Source: Vayikra Rabbah 23:9 (on the arayos section, Parshas Acharei Mos); see also Midrash Tanchuma, Acharei Mos 6.
• The Midrash frames the arayos prohibitions as the defining boundary between a holy nation and the corrupt cultures of Mitzrayim and Canaan. It emphasizes that Israel is commanded not only to avoid the final act of immorality, but to live with a different standard of relational conduct entirely — one of restraint, distinction, and kedushah. By highlighting that the surrounding nations fell specifically through unrestrained intimacy, the Midrash reinforces that holiness is preserved through disciplined distance. In this light, לא תקרבו — do not approach is not merely a technical restriction, but part of a larger Torah demand to build a חיים של קדושה — a life structured by moral boundaries that prevent decline before it begins.

Rashi

• Source: Rashi on Leviticus 18:6.
• Rashi reads לא תקרבו as a warning not to come near conduct that leads to גילוי ערוה — sexual uncovering. His contribution is the plain directional meaning of the verse: the Torah prohibits proximity because proximity is already the beginning of transgression. The mitzvah is thus not detached from the final aveirah; it is the Torah’s naming of the first stage of it.

Ibn Ezra

• Source: Ibn Ezra on Leviticus 18:6.
• Ibn Ezra sharpens the meaning of “approach” by showing that the Torah is legislating conduct, not merely intention. The language of the verse is active and relational. His nuance is that arayos are not violated only by abstract desire, but by concrete movement into closeness. The mitzvah therefore governs embodied behavior.

Sforno

• Source: Sforno on Leviticus 18:6.
• Sforno emphasizes the preventive wisdom of the Torah’s wording. The prohibition addresses actions that awaken and strengthen passion before the complete aveirah occurs. His reading highlights the mechanism of spiritual decline: sin is often prepared gradually. This mitzvah interrupts that process at the point where passion begins to take permitted-looking form.

Ramban

• Source: Ramban, Hasagos to Sefer HaMitzvos on the lav of לא תקרבו; Ramban on Leviticus 18:6.
• Ramban is crucial here because he disputes Rambam’s scope. He holds that many forms of affectionate contact are indeed forbidden, but he questions whether all such acts are included as an independent Torah lav from this verse, suggesting that the verse may serve more as a warning framework and that the biblical core is narrower. His contribution is not leniency in spirit, but precision in classification. He teaches that one must distinguish carefully between what is prohibited and how the prohibition is categorized.

Rabbeinu Bachya

• Source: Rabbeinu Bachya on Leviticus 18:6.
• Rabbeinu Bachya explains that the Torah places its fence at the stage of approach because once intimacy begins to form, the moral line is already weakened. His nuance is that distance is not external to kedushah; it is one of kedushah’s essential tools. By forbidding first contact, the Torah protects the person from the inner confusion that precedes open violation.

Abarbanel

• Source: Abarbanel on Leviticus 18.
• Abarbanel reads the arayos section as part of the Torah’s ordering of human relationships, family structure, and social sanctity. Within that system, קריבה is not a private matter alone. It destabilizes the boundaries on which trust and household order depend. His refinement is that forbidden closeness damages more than the individual act; it disturbs an entire relational architecture.

Ramban

• Source: Ramban on Leviticus 19:2, קדושים תהיו.
• Ramban’s broader concept of kedushah helps frame this mitzvah within Torah structure. Kedushah is not achieved only by avoiding the explicitly forbidden at the final stage. It requires disciplined restraint even within areas where the person might otherwise seek indulgence. Mitzvah 175 therefore belongs to the Torah’s larger project of forming a life in which bodily desire is governed by holiness rather than treated as self-authorizing.

Sforno

• Source: Sforno on Leviticus 19:2.
• Sforno understands kedushah as a state in which human powers are ordered toward higher purpose rather than scattered through sensuality. Within that framework, the prohibition of pleasurable contact with arayos is not an isolated restriction. It is part of the Torah’s effort to preserve the person’s inner alignment, so that physical life remains under the rule of the soul and covenant.

Rabbeinu Bachya

• Source: Rabbeinu Bachya on Leviticus 18:6.
• Rabbeinu Bachya conceptually locates this mitzvah in the Torah’s method of building protective boundaries before moral collapse. The broader framework is that the Torah does not rely on last-minute resistance. It builds sanctity structurally, by legislating the stages that shape the final outcome. Mitzvah 175 is therefore a system-law of kedushah, not only a narrow conduct rule.

Abarbanel

• Source: Abarbanel, introduction and discussion on Leviticus 18.
• Abarbanel presents the arayos laws as part of the covenantal ordering of family, lineage, and social life. In that larger Torah design, forbidden intimacy is disruptive because it confuses the distinctions by which a holy society is built. This mitzvah’s role, then, is to preserve the integrity of relational boundaries before they are broken in more drastic form.

Shulchan Aruch

• Source: Shulchan Aruch, Even HaEzer 21:1.
• The Shulchan Aruch rules that affectionate physical contact with women who are forbidden as arayos is prohibited, including acts such as embracing and kissing when they are expressions of intimacy. The practical point is that the halacha does not wait for full illicit relations before it speaks. Physical nearness that carries erotic or affectionate character is itself part of the issur — prohibition.

Shulchan Aruch

• Source: Shulchan Aruch, Even HaEzer 21.
• This siman also addresses surrounding conduct that cultivates illicit attraction, including modes of looking and social behavior that are not neutral when they are pursued for enjoyment. The practical structure of the mitzvah therefore includes more than touch alone. It includes the real-world conditions that produce closeness and lower restraint.

Shulchan Aruch

• Source: Shulchan Aruch, Yoreh Deah 195.
• In the laws of niddah, the Shulchan Aruch gives concrete expression to the Torah’s idea of לא תקרבו through forms of separation and harchakos — distancing practices. Even where husband and wife are otherwise fully permitted to one another, the period of niddah creates a temporary status of prohibition that demands behavioral boundaries. This shows how seriously halacha treats the category of forbidden nearness.

Nosei Keilim

• Source: Beis Shmuel and Chelkas Mechokek on Even HaEzer 21.
• The nosei keilim clarify scope and application, especially around what counts as conduct of affection and what is considered part of the prohibited atmosphere of intimacy. Their role is not to reinvent the mitzvah, but to sharpen its practical definition. The halachic takeaway is that the mitzvah is governed not by vague feeling, but by normative categories of closeness, affection, and prohibited familiarity.

Netziv

• Source: HaEmek Davar on Leviticus 18.
• Netziv understands arayos as part of the Torah’s construction of a holy national life, not merely private restraint. The sanctity of Israel depends on ordered family boundaries and disciplined human conduct. Mitzvah 175 therefore protects the covenantal texture of the nation by forbidding the early forms of relational breakdown.

Rav Shimshon Raphael Hirsch

• Source: Hirsch on Leviticus 18:6.
• Hirsch emphasizes that Torah morality does not reduce the person to instinct. The human body is placed under mission, dignity, and covenant. In that light, the prohibition of intimate contact with forbidden women teaches that desire may be strong without being sovereign. The mitzvah becomes a statement about human nobility under Divine law.

Malbim

• Source: Malbim on Leviticus 18:6.
• Malbim reads the Torah’s language with precision, showing that קריבה — approach is itself a meaningful category and not merely rhetorical introduction. His broader contribution is that Torah law names stages of moral action with deliberate exactness. By doing so, it teaches that corruption develops through discernible steps, and holiness requires intervention before the final breach.

Meshech Chochmah

• Source: Meshech Chochmah on the arayos section in Leviticus.
• Meshech Chochmah frames the arayos laws as part of the Torah’s protection of the sanctity of family order and the stability of social life. Prohibited intimacy is not only a personal failing. It weakens the forms through which covenantal life is transmitted and preserved. Mitzvah 175 stands at the front end of that protection.

Rav Kook

• Source: Rav Kook, themes of kedushah and disciplined human elevation in Orot HaKodesh and related writings.
• Rav Kook understands kedushah not as hostility to life, but as the elevation of life through right order. Desire is a real human force, but holiness depends on refining it rather than letting it rule unchecked. This mitzvah expresses that principle in concrete form: by restricting forbidden closeness, the Torah lifts embodied life into a higher order rather than abandoning it to impulse.

Tanya

• Source: Tanya, especially chapters 12 and 27.
• Tanya teaches that the holiness of a person is revealed not by never feeling conflict, but by ruling thought, emotion, and action under the authority of the nefesh haElokis — the Divine soul. In the context of this mitzvah, forbidden closeness is significant because bodily action is never merely bodily. To refuse such contact is to affirm that desire does not define the self. The person’s truest identity is expressed through mastery, not surrender.

Sfas Emes

• Source: Sfas Emes, Acharei Mos / Kedoshim.
• Sfas Emes repeatedly presents kedushah as beginning at the point where a person guards the threshold of action and does not let holiness be decided only after momentum has already formed. Applied here, the mitzvah is an avodah of guarding beginnings. One protects the inner point of holiness by not allowing forbidden closeness to become normal, familiar, or inwardly justified.

Shem MiShmuel

• Source: Shem MiShmuel, Acharei Mos / Kedoshim.
• Shem MiShmuel often explains that the Torah’s boundaries preserve the unity of the soul by preventing a person from becoming divided between holy aspiration and unruled appetite. This mitzvah reflects that inner structure. When a person refuses forbidden intimacy at the stage of approach, he preserves inner wholeness and keeps his powers aligned rather than fractured.

Ramchal

• Source: Mesillas Yesharim, chapters 11 and 16.
• Ramchal describes נקיות — cleanliness from sin and קדושה — holiness as requiring vigilance precisely in areas where desire deceives the person into rationalization. Mitzvah 175 fits that map exactly. Its inner work is to remove the false innocence from conduct that is already spiritually dangerous. The mitzvah refines the person by making him honest about what closeness does to the heart.

This mitzvah appears in the Torah’s major section of arayos in Parshas Acharei Mos, where the Torah defines the prohibited relationships that preserve the sanctity of family and the distinct holiness of Israel. Its wording is notable because it does not begin with the final act, but with קריבה — approach, indicating that the Torah legislates the zone leading into sexual transgression and not only the endpoint.

Within Rambam’s count, Mitzvah 175 functions as a kind of summary prohibition around the arayos system. Many earlier mitzvos in this section identify particular forbidden relationships, while this mitzvah addresses the category of intimate nearness to any forbidden woman. It therefore sits at the meeting point of boundary law, personal kedushah, and the Torah’s larger concern for preserving the structure of family life.

Practically, the mitzvah also forms part of the background to later halachic systems of distancing, especially in the laws of niddah and in the broader laws governing modest interaction and forbidden familiarity. Its role is not to repeat every specific ervah, but to state that even before the central prohibition is violated, Torah already demands sanctified distance.
