Prohibitions in Judaism

Of course. It’s important to first understand that Jewish law, or Halakha, is a complex and nuanced legal system derived from the Hebrew Bible (the Tanakh) and elaborated upon in the Talmud and later rabbinic literature.

The prohibitions are not simply a list of “don’ts” but are part of a comprehensive covenant between God and the Jewish people, designed to create a holy and ethical society.

Here is a breakdown of prohibited things and acts, categorized for clarity, with their sources in the Torah (the first five books of the Tanakh) and their subsequent development in Jewish law.

I. Ethical and Interpersonal Prohibitions (Laws Between People)

These are often considered the foundation of a just society.

  • Murder: Explicitly forbidden in the Ten Commandments. (Exodus 20:13)
  • Theft and Kidnapping: Stealing property or a person is strictly prohibited. (Exodus 20:13, Leviticus 19:11)
  • Lying and Bearing False Witness: Prohibited in the Ten Commandments; considered a grave sin that perverts justice. (Exodus 20:13)
  • Deceit in Business: Using false weights and measures is explicitly forbidden. (Leviticus 19:35-36)
  • Spreading Gossip or Slander (Lashon Hara): Considered a very serious sin, derived from “Do not go about as a talebearer among your people.” (Leviticus 19:16)
  • Taking Revenge or Bearing a Grudge: Actively forbidden. (Leviticus 19:18)
  • Causing Embarrassment: To publicly embarrass someone is considered akin to murder in Talmudic thought.
  • Oppressing the Stranger, Widow, or Orphan: Repeatedly emphasized as a core ethical imperative. (Exodus 22:21-22)
  • Hating Your Brother in Your Heart: The Torah commands rebuke rather than silent hatred. (Leviticus 19:17)
  • Putting a Stumbling Block Before the Blind: A biblical metaphor for not misleading the ignorant or taking advantage of someone’s weakness. (Leviticus 19:14)

II. Ritual and Religious Prohibitions (Laws Between People and God)

These laws govern the sacred relationship with God and ritual purity.

  • Idolatry (Avodah Zarah): The most severe prohibition in Judaism, strictly forbidden in the Ten Commandments. This includes worshiping other gods, creating idols, and certain practices associated with idolatry. (Exodus 20:3-5)
  • Blasphemy: Cursing or reviling the name of God is a capital offense in the Torah. (Leviticus 24:16)
  • Violating the Sabbath (Shabbat): Performing any of the 39 categories of creative work (melakhah) is forbidden. This includes lighting a fire, carrying in public, and all forms of labor. (Exodus 20:10, Exodus 35:2-3)
  • Eating Non-Kosher Foods (Kashrut):
    • Forbidden Animals: Only land animals that chew their cud and have split hooves are permitted (e.g., cows, sheep). Animals lacking both (e.g., pigs, rabbits) are forbidden. (Leviticus 11)
    • Forbidden Sea Creatures: Only those with fins and scales are permitted. Shellfish (shrimp, lobster) and eels are forbidden.
    • Forbidden Birds: Listed primarily by species in the Torah (e.g., eagles, owls).
    • Insects: With a few specific exceptions, all are forbidden.
    • Blood: Consuming blood is strictly prohibited. Meat must be koshered (soaked and salted) to remove the blood. (Leviticus 7:26-27)
    • Mixing Meat and Milk (Basar b'Chalav): Forbidden based on the verse “Do not cook a kid in its mother’s milk.” (Exodus 23:19)
  • Certain Sexual Relations (Arayot): The Torah prohibits specific relationships, including:
    • Adultery (Exodus 20:13)
    • Incest (Leviticus 18)
    • Homosexual relations (between men) (Leviticus 18:22)
    • Bestiality (Leviticus 18:23)

III. Prohibitions Related to the Body and Appearance

  • Tattoos: Explicitly forbidden in the Torah. “You shall not make gashes in your flesh for the dead, or incise any marks on yourselves.” (Leviticus 19:28)
  • Certain Mourning Practices: Specific acts like shaving the sides of the head or marring the edges of the beard are prohibited. (Leviticus 19:27-28)
  • Cross-Dressing: “A woman shall not wear that which pertains to a man, neither shall a man put on a woman’s garment.” (Deuteronomy 22:5)

IV. Prohibitions in Agriculture and Commerce

  • Sowing Mixed Seeds (Kilayim): Forbidden to sow a field with two different kinds of seeds. (Leviticus 19:19)
  • Wearing Mixed Fabrics (Shaatnez): Wearing a garment of mixed wool and linen is forbidden. (Deuteronomy 22:11)
  • Charging Interest to Fellow Jews: Lending money with interest to another Jew is prohibited. (Leviticus 25:36-37)

V. Prohibitions Involving Magic and the Occult

The Torah strongly forbids attempts to manipulate or divine the future through supernatural means outside of the divine covenant.

  • Sorcery and Witchcraft: Explicitly forbidden. (Exodus 22:17, Deuteronomy 18:10)
  • Necromancy (Ov and Yidoni): Consulting with the dead is prohibited. (Deuteronomy 18:11)
  • Divination, Soothsaying, and Interpreting Omens: All are listed as abominations. (Deuteronomy 18:10-12)

Important Nuances to Understand:

  1. Context and Interpretation: The simple text of the Torah is the starting point. For example, “an eye for an eye” was interpreted by the rabbis of the Talmud to mean monetary compensation, not literal physical retaliation.
  2. Severity: Not all prohibitions are equal. The most severe sins, like murder and idolatry, are in a category of their own. Violating the Sabbath is serious, but not on the same level.
  3. Applicability: Some laws apply only in the Land of Israel, some only to Kohanim (priests), and some only to men or women.
  4. The Spirit of the Law: Jewish law is not just about technical compliance. The ethical underpinnings—justice, compassion, and holiness—are considered the ultimate goal.

This list is a representative sample, not an exhaustive one. The complete body of Jewish law contains 613 commandments (Taryag Mitzvot), 365 of which are prohibitions.

ADHERENTS OF PROHIBITIONS OF FAITH

Of course. This is another excellent question that, like the previous ones, cannot be answered with a single, precise percentage. Adherence to prohibitions in Judaism exists on a vast spectrum, and the level of observance is often the primary defining factor between different Jewish denominations and individual practice.

Instead of a single number, it’s best to understand the approximate adherence levels by grouping them according to the major Jewish movements and their interpretive approaches to Jewish law (Halakha).

The Spectrum of Observance in Judaism

The following breakdown provides a general guide to how different groups relate to the system of prohibitions. It’s crucial to remember that there is significant diversity within each group.

1. Orthodox Judaism

(~10% of U.S. Jews, higher percentages in Israel and Europe)

Orthodoxy holds that the Torah is the divine word of God and that the Halakhic system, as developed by the rabbis, is binding.

  • Approximate Adherence: 95-100% for the core prohibitions relevant to their daily lives.
  • Key Characteristics:
    • Kashrut: Strict, scrupulous observance of kosher laws at home and outside. Separate dishes for meat and dairy, only certified kosher food products.
    • Shabbat: Strict prohibition against the 39 categories of creative work (melakhah). This means no driving, using electricity, writing, or handling money from Friday sunset to Saturday night.
    • Taharat HaMishpacha (Family Purity): Adherence to laws of ritual purity, including immersion in a mikveh (ritual bath) and abstaining from physical contact during a woman’s menstrual period.
    • Daily Life: Observance of daily prayers, wearing of kippah (head covering) and tzitzit (fringed garment) for men, and laws of modesty in dress.

2. Conservative Judaism

(~15-20% of U.S. Jews)

Conservative Judaism believes in the binding nature of Jewish law but holds that it has always evolved and adapted to historical circumstances. Its rabbinic authority makes legal decisions for the movement.

  • Approximate Adherence: Varies widely, but a significant majority strive to observe core prohibitions, often with a more modern interpretation than Orthodoxy.
  • Key Characteristics:
    • Kashrut: High level of observance. Most members keep kosher homes, and the movement strongly advocates for kosher standards. Observance outside the home may be more flexible.
    • Shabbat: Strong emphasis on Shabbat observance, but the interpretation of “work” may differ. Many will refrain from work-related activities and shopping but may use electricity or drive to attend synagogue services.
    • Other Laws: Commitment to observing Jewish holidays, daily prayers, and life cycle events according to Halakha, though individual practice varies more than in Orthodoxy.

3. Reform and Reconstructionist Judaism

(Reform is the largest denomination in the U.S., ~35%)

These movements see Jewish law as a set of non-binding guidelines, a “moral compass” that individuals can choose to adopt based on their own conscience and its relevance to modern life. The emphasis is on ethical monotheism and social justice over ritual observance.

  • Approximate Adherence: Low for ritual prohibitions, high for ethical ones.
  • Key Characteristics:
    • Kashrut: Generally not observed. Some individuals or families may choose to avoid pork and shellfish as a cultural identifier, but full kosher observance is rare.
    • Shabbat: The focus is on making Shabbat “holy” through family meals, study, or community service, rather than on the traditional prohibitions. Driving, using electronics, and other activities are common.
    • Ethical Laws: The ethical prohibitions (against murder, theft, gossip, injustice) are upheld as the core of the religion and are widely adhered to.
    • Personal Autonomy: The individual’s informed choice is the ultimate authority on which practices and prohibitions to follow.

4. Secular/Cultural Jews

(A very large group, especially in Israel and the diaspora)

This group identifies as Jewish ethnically, culturally, or by nationality, but not religiously. They do not believe Jewish religious law is binding.

  • Approximate Adherence: Minimal to none for ritual prohibitions.
  • Key Characteristics:
    • Kashrut: Typically not observed, though some in Israel may follow kosher guidelines out of social convenience.
    • Shabbat: Treated as a day of rest or a weekend, with no religious restrictions.
    • Holidays: Jewish holidays are often celebrated as cultural or national events (e.g., Passover Seder, Hanukkah) but without adherence to the associated religious prohibitions (e.g., not eating chametz on Passover).

Summary by Prohibition Type

To give a clearer picture, here is a rough, estimated adherence level for specific prohibitions across the entire Jewish population: Prohibition Approximate Global Adherence Notes Ethical Prohibitions (Murder, Theft, Lying) ~99%+ Universally accepted as binding by all denominations and secular Jews. Eating Pork ~30-40% Observed by Orthodox, Conservative, and some Reform/Cultural Jews. Avoidance of pork is a strong cultural marker. Keeping Fully Kosher Home ~20-30% Primarily Orthodox and Conservative Jews, plus some others. Observing Shabbat Prohibitions (no driving, electricity, etc.) ~10-20% Primarily the Orthodox and some Conservative Jews. Taharat HaMishpacha (Family Purity) ~10-15% Primarily observed within the Orthodox community and some in the Conservative movement.

Conclusion

There is no “average Jew” when it comes to adherence to prohibitions. The level of observance is fundamentally a question of which stream of Judaism one identifies with.

  • For Orthodox Jews, adherence is near-total and defines their daily existence.
  • For Conservative Jews, adherence is high but with modern adaptations.
  • For Reform Jews, adherence is a matter of personal choice, focused more on ethics than ritual.
  • For Secular Jews, the ritual prohibitions are largely irrelevant, while the ethical and cultural elements remain powerful.

Therefore, any percentage is an aggregate of these vastly different approaches to the faith and its laws.
