Jewish ethical teachings on sexual ethics: HSC Studies of Religion
“Ethics: describe and explain Jewish ethical teachings on bioethics OR environmental ethics OR sexual ethics (this page: sexual ethics)”
Judaism sees sexuality as a good gift of God, holy within marriage: "It is not good for the Human to be alone" (Genesis 2:18); husband and wife "become one flesh" (2:24). Intimacy in marriage is a mitzvah: the husband owes his wife onah (Exodus 21:10) and may not force her (Eruvin 100b). Procreation is the Torah's first commandment, "Be fertile and increase" (Genesis 1:28), fulfilled with a son and a daughter (Mishnah Yevamot 6:6). Boundaries include the prohibition of adultery (Exodus 20:13), the forbidden relations of Leviticus 18, and niddah (18:19) with immersion in the mikveh. Modesty (tzniut) is protected by yichud (Mishnah Kiddushin 4:12) and negiah. Contraception is limited in traditional law (Yevamot 12b); abortion is permitted when the mother's life is at risk, since "her life comes before" the fetus (Mishnah Oholot 7:6). Orthodox Jews keep these laws as binding; Conservative Jews reinterpret some (2006 responsa); Reform Jews stress ethical principles, accepting same-sex marriage.

What this dot point is asking
The ethics component of the Judaism depth study asks you to describe and explain Jewish ethical teachings in ONE area. This page covers sexual ethics: teachings about sexuality, marriage, fidelity, procreation, modesty, contraception, abortion and sexual orientation.
It is a strong choice. NESA's 2025 guidelines for the 20-mark Judaism question (Q32) built their "answers could include" list around sexual ethics: sexuality as "a positive action" and "a legitimate good, a mitzvah" within "a sanctified marriage", procreation, the traditional position on birth control and abortion with its exceptions, modesty and negiah, the prohibition of adultery, and "the diversity of Jewish thought".
Treat the topic with maturity and respect. Describe teachings as the different Jewish movements understand them and distinguish Orthodox Judaism (halakhah, Jewish law, is binding and unchanging in its principles), Conservative/Masorti Judaism (halakhah is binding but develops) and Reform/Progressive Judaism (halakhah guides but individual ethical autonomy decides).
Tanakh (JPS): Genesis 1:28 ("Be fertile and increase"); 2:18 ("not good for the Human to be alone"); 2:24 ("one flesh"); Exodus 20:13 ("You shall not commit adultery"); Exodus 21:10 (onah, "conjugal rights"); Leviticus 18 (forbidden relations; 18:19 niddah; 18:22); Song of Songs. Mishnah: Yevamot 6:6 (a son and a daughter); Kiddushin 4:12 (yichud); Oholot 7:6 ("her life comes before"); Yadayim 3:5 (Song of Songs "the holy of holies"). Talmud: Yevamot 62b (a man without a wife is "without joy, without blessing, without goodness"); Yevamot 12b (three women and contraception); Eruvin 100b (no coercion). Maimonides: Forbidden Intercourse 21:1 (negiah). Terms: kedushah, kiddushin, ketubah, onah, pru u'rvu, niddah, mikveh, taharat ha-mishpacha, tzniut, yichud, negiah.
The answer
The foundations of Jewish sexual ethics
- Holiness (kedushah). Jewish ethics rest on imitating God's holiness: "You shall be holy, for I, the ETERNAL your God, am holy" (Leviticus 19:2). Holiness in sexual life means ordering desire within covenant, not suppressing it.
- The Torah and halakhah. The written Torah gives the core commandments; the Mishnah, the Talmud and the codes of Maimonides and the Shulchan Aruch develop them into halakhah. NESA's 2025 guidelines note "a continual interaction between Halacha (Jewish law) and ethical issues confronting society".
- Community. Jewish ethics are "for the whole community not just the individual" (NESA 2025): family and communal life, not only personal choice, are at stake.
Teaching 1: sexuality is good, and holy within marriage
- Created for companionship. "The ETERNAL God said, 'It is not good for the Human to be alone; I will make a fitting counterpart for him'" (Genesis 2:18). "Hence a man leaves his father and mother and clings to his wife, so that they become one flesh" (2:24).
- Marriage as a blessing. The Talmud teaches: "Any man who does not have a wife is left without joy, without blessing, without goodness" (Yevamot 62b).
- Love poetry in Scripture. The Song of Songs celebrates erotic love; Rabbi Akiva called it "the holy of holies" among the sacred writings (Mishnah Yadayim 3:5).
- Not celibacy. Unlike traditions that honour celibacy as a higher path, Judaism regards marriage and sexual intimacy as the norm for a holy life, including for rabbis.
Application. Sexual relations belong within kiddushin (marriage, literally "sanctification"). NESA's 2025 guidelines: "It regards sex when it occurs within a sanctified marriage as a legitimate good, a mitzvah which is an act compatible with holiness."
Teaching 2: onah, mutual obligation and consent
- Onah. The Torah says a husband "must not withhold from this one her food, her clothing, or her conjugal rights" (Exodus 21:10). The rabbis understood the third as the wife's right to sexual intimacy; the Mishnah even sets how often, according to the husband's occupation (Ketubot 5:6). The ketubah (marriage contract) records the husband's obligations to his wife.
- Consent. "Rami bar Hama said that Rav Asi said: It is prohibited for a man to force his wife in the conjugal mitzva" (Eruvin 100b). The same passage condemns causing the wife "pain or distress".
Application. Jewish sexual ethics protects the wife's rights and dignity, grounding modern Jewish teaching on mutual respect, consent and the rejection of marital coercion.
Teaching 3: procreation (pru u'rvu)
- The first commandment. "Be fertile and increase, fill the earth" (Genesis 1:28).
- Its measure. "A man may not neglect the mitzva to be fruitful and multiply unless he already has children. Beit Shammai say: One fulfills this mitzva with two males, and Beit Hillel say: A male and a female" (Mishnah Yevamot 6:6). The halakha follows Beit Hillel, and the Talmud encourages having more children beyond this minimum (Yevamot 62b).
Application.
- Contraception. Traditional law generally restricts contraception, especially before the mitzvah is fulfilled, but permits it where pregnancy would endanger health: "Three women may engage in relations with a contraceptive resorbent ... A minor, a woman who is already pregnant, and a nursing woman" (Yevamot 12b). Orthodox couples consult a rabbi; Conservative and Reform Jews generally accept contraception as a matter of personal responsibility.
- Infertility. Because children are so valued, Jewish communities generally support fertility treatment, and Israel's public health system funds IVF extensively. (IVF is also a bioethics topic.)
Teaching 4: boundaries in sexual life
- Adultery. "You shall not commit adultery" (Exodus 20:13; Deuteronomy 5:17). Adultery breaks the covenant of marriage and, as NESA notes, is "a category distinct from sexual relations before marriage".
- Forbidden relations (arayot). Leviticus 18 lists prohibited unions, including incest, adultery, and "Do not lie with a male as one lies with a woman" (18:22).
- Niddah and family purity (taharat ha-mishpacha). "Do not come near a woman during her menstrual period of impurity to uncover her nakedness" (Leviticus 18:19). In Orthodox practice the couple refrain from intimacy during menstruation and a further set of days; the wife then immerses in a mikveh (ritual bath) and relations resume. Many observant couples describe this monthly cycle of separation and reunion as renewing their marriage.
Teaching 5: modesty (tzniut), yichud and negiah
- Tzniut (modesty) in dress, speech and behaviour protects the dignity of both men and women and keeps sexuality private.
- Yichud. "A man may not be secluded with two women lest he sin with them" (Mishnah Kiddushin 4:12); more broadly, a man and a woman who are not married or closely related should not be secluded together.
- Negiah. Maimonides rules that intimate physical contact "out of desire" with a forbidden partner is prohibited by Scripture (Laws of Forbidden Intercourse 21:1), which Orthodox communities apply as a restriction on touching between unmarried men and women. NESA's 2025 guidelines note that teachings on modesty and negiah "are designed to support couples to avoid this type of intimacy before a sanctified marriage".
Teaching 6: abortion and the sanctity of life
- The Mishnah: "If a woman is having trouble giving birth, they cut up the child in her womb ... because her life comes before the life of [the child]. But if the greater part has come out, one may not touch it, for one may not set aside one person's life for that of another" (Oholot 7:6).
- The fetus is valued and abortion is not permitted casually, but the mother's life, and for many authorities her serious physical or mental health, takes precedence. NESA's 2025 guidelines: Jewish law "traditionally opposes birth control or abortion, but it allows exceptions, especially when the mother's physical or psychological health is at risk".
Diversity: how the movements apply the teachings
| Issue | Orthodox | Conservative (Masorti) | Reform / Progressive |
|---|---|---|---|
| Authority of halakhah | Binding | Binding but evolving | Guidance; ethical autonomy |
| Sex before marriage | Forbidden; negiah and yichud observed | Discouraged; the laws of negiah are not generally observed | Judged by ethical values (commitment, honesty, consent) |
| Niddah and mikveh | Observed | Observed by some | Generally not observed; some reclaim the mikveh with new meanings |
| Contraception | In defined circumstances with rabbinic guidance | Generally permitted | Permitted |
| Same-sex relationships | Homosexual acts forbidden (Leviticus 18:22); emphasis on compassion varies | 2006 law committee responsa, one lifting most restrictions and allowing gay and lesbian rabbis | Accepted, including same-sex marriage |
Evaluating Jewish sexual ethics
- Strengths. A positive view of sexuality; strong protection of the wife's rights and consent from ancient times; clear commitment to fidelity and family.
- Tensions. Traditional texts on sexual orientation and gender roles are read very differently across movements, and debate continues within Orthodoxy about how to include gay Jews with compassion.
- Navigating the world today. Jewish sexual ethics offer, in NESA's words, "a moral compass for adherents offering guidance in navigating the modern world's complex sexual ethics issues", while "the diversity of Jewish thought ensures that there is always room for personal interpretation".
Step 1: Choose two clearly distinct teachings
For example, sexuality as holy within marriage (with onah and consent) and the mitzvah of procreation. Avoid two versions of "no adultery".
Step 2: Give each a source
Genesis 2:18 and 2:24, Exodus 21:10, Eruvin 100b for the first; Genesis 1:28 and Mishnah Yevamot 6:6 for the second.
Step 3: Explain what each requires of adherents
Fidelity, mutual obligation and consent; having children and attitudes to contraception and fertility treatment.
Step 4: Show diversity in one sentence
Note that Orthodox Jews apply these as binding halakhah while Reform Jews treat them as ethical guidance.
- Presenting Judaism as negative about sexuality
- Sexual intimacy within marriage is a mitzvah and a good gift.
- Treating all Jews as Orthodox
- Distinguish the movements, especially on contraception, premarital sex and same-sex relationships.
- Missing the rights of the wife
- Onah and the prohibition on coercion (Exodus 21:10; Eruvin 100b) are distinctive and well sourced.
- Confusing niddah with a judgement on women
- It is a law of ritual status and holiness in marriage, not a statement of moral impurity.
- Saying Judaism forbids all abortion
- The mother's life takes precedence (Mishnah Oholot 7:6).
In one sentence
Jewish sexual ethics treat sexuality as a holy gift of God within marriage, grounded in Genesis 1:28 and 2:18-24, protected by onah and the prohibition on coercion, bounded by the prohibition of adultery, the laws of Leviticus 18, niddah and modesty, and applied with different degrees of strictness by Orthodox, Conservative and Reform Jews.

In your response, refer to ONE of the following areas: Bioethics, Environmental ethics, Sexual ethics.Show worked answer →
Criteria (NESA 2025 marking guidelines, SoR II Q32). 17 to 20: a comprehensive analysis of how the ethical teachings of Judaism guide adherents to navigate the world today; integrates the stimulus effectively throughout; a cohesive, well-structured response with detailed, relevant and accurate information; relevant and accurate terminology. 13 to 16: thorough. 9 to 12: analysis. 5 to 8: description. 1 to 4: general statements.
What NESA's "answers could include" list chose: sexual ethics. Jewish ethics rest on the holiness of God, apply to the whole community, and direct daily life; the sources are the Ten Commandments, the Prophets and Proverbs, in "continual interaction" with halakhah. It described sexuality as "a positive action", "a legitimate good, a mitzvah" within "a sanctified marriage"; the importance of procreation; the traditional opposition to birth control and abortion "but it allows exceptions, especially when the mother's physical or psychological health is at risk"; modesty and negiah; the prohibition of adultery; and "the diversity of Jewish thought".
A top-band structure.
- Thesis on the stimulus. What Jews uphold (the holiness of sexuality within marriage, procreation, consent, family purity) comes from sacred texts (Torah, Mishnah, Talmud, codes) and is interpreted in lived experience by different movements.
- Sexuality as good within marriage: Genesis 2:18, 2:24; onah (Exodus 21:10); consent (Eruvin 100b).
- Procreation: Genesis 1:28; Mishnah Yevamot 6:6. Navigating today: fertility treatment is widely supported; contraception is permitted in defined cases (Yevamot 12b) and more widely by liberal movements.
- Boundaries: adultery (Exodus 20:13), Leviticus 18; niddah and mikveh; modesty, yichud (Mishnah Kiddushin 4:12) and negiah.
- Abortion: the mother's life comes first (Mishnah Oholot 7:6).
- Diversity today: Orthodox, Conservative (2006 CJLS responsa) and Reform approaches to same-sex relationships and premarital sex.
- Evaluation, returning to the stimulus.

- Criteria (NESA 2025 marking guidelines, SoR I Q16(b), SoR II Q27(b))
- 5 marks: a thorough explanation of TWO ethical teachings relevant to the chosen area, integrating relevant and accurate terminology. 4: sound. 3: explanation of TWO. 2: description of at least ONE. 1: statements about Judaism. (NESA's sample answer chose bioethics, with pikuach nefesh and lo tirtzach.)
- A 5-mark answer on sexual ethics
- Teaching 1: sexuality is holy within marriage
- God said, "It is not good for the Human to be alone" (Genesis 2:18), and husband and wife "become one flesh" (2:24). Sexual intimacy in marriage is a mitzvah, and the husband must not withhold his wife's "conjugal rights" (onah, Exodus 21:10). The Talmud forbids a man to "force his wife" (Eruvin 100b), so consent and mutual pleasure are part of the ethic. Adultery is forbidden by the Ten Commandments.
- Teaching 2: the mitzvah of procreation
- "Be fertile and increase" (Genesis 1:28) is the Torah's first commandment. The Mishnah rules that a man "may not neglect the mitzva to be fruitful and multiply unless he already has children", which Beit Hillel defines as "a male and a female" (Yevamot 6:6). This shapes Jewish attitudes to contraception (limited in Orthodox law) and support for fertility treatment.

Criteria (NESA 2024 marking guidelines, SoR I Q16(a), SoR II Q27(a)). (i) 2 marks: outlines ONE ethical teaching in Judaism. (ii) 5 marks: a detailed and accurate explanation of how the teaching is reflected within Judaism in the chosen area, integrating relevant and accurate terminology.
(i) Outline. The seventh commandment, "You shall not commit adultery" (Exodus 20:13), part of the divinely given moral law, protects the covenant of marriage.
(ii) Reflected in sexual ethics.
- Marriage as covenant. Sexual relations belong within kiddushin (marriage), which sets the couple apart for each other; the ketubah records the husband's obligations, including onah (Exodus 21:10).
- Guarding the boundary. Rabbinic "fences" protect fidelity: the laws of yichud forbid seclusion that could lead to sin (Mishnah Kiddushin 4:12), and negiah limits physical contact outside marriage in Orthodox practice.
- Family purity. Niddah (Leviticus 18:19) and immersion in the mikveh regulate intimacy even within marriage, renewing it each month.
- Diversity. All movements uphold fidelity; they differ on premarital sex and same-sex relationships.

Plan using onah and consent in sexual ethics.
- Teaching. Within marriage, sexual intimacy is a mitzvah and a duty the husband owes his wife (onah, Exodus 21:10); it must be with her consent (Eruvin 100b).
- Stimulus. "Trust in the Lord" connects to the belief that sexuality is God's good gift (Genesis 2:18, 2:24), and "do good" to treating one's spouse with love, respect and care.
- Application. Couples keep faith with each other, avoid adultery, and in traditional practice observe niddah and the mikveh, which Jews describe as renewing the marriage each month.
- Effect. Sexual ethics becomes a way of sanctifying daily life in covenant with God.

foundation3 marksOutline the Jewish teaching on sexuality within marriage. (Original)Show worked solution →
Judaism teaches that sexuality is a good gift of God to be expressed within marriage. God said, "It is not good for the Human to be alone" (Genesis 2:18), and husband and wife "become one flesh" (2:24). Intimacy is a mitzvah: the husband must provide his wife's "conjugal rights" (onah, Exodus 21:10), and the Talmud forbids him to force her (Eruvin 100b). Adultery is forbidden by the Ten Commandments.
Marking: 1 for sexuality as good within marriage, 1 for a source, 1 for onah, consent or fidelity.
core5 marksExplain how the laws of family purity (niddah and mikveh) express Jewish beliefs. (Original)Show worked solution →
- The practice
- The Torah forbids marital relations during menstruation (Leviticus 18:19). In Orthodox practice the couple separate during the woman's period and for a further set of days, after which she immerses in a mikveh and relations resume.
- Beliefs expressed
- (1) Holiness (kedushah): sexuality is sacred and ordered by God's law, not by impulse. (2) Covenant and halakhah: observing the commandment expresses obedience to the Torah. (3) Respect and renewal: many observant Jews describe the monthly separation as building non-physical intimacy and renewing desire, so that marriage is continually re-sanctified.
- Diversity
- Orthodox Jews observe the laws fully; many Conservative and Reform Jews do not, though some have reclaimed the mikveh with new meanings.
Marking (Original): 5 for accurate description, sources, at least two beliefs linked, and awareness of diversity.
exam7 marksEvaluate the extent to which Jewish sexual ethics are shared across Orthodox, Conservative and Reform Judaism. (Original)Show worked solution →
- Shared
- All movements regard sexuality as a good gift of God, value marriage and family, forbid adultery (Exodus 20:13), require consent and mutual care (Eruvin 100b), and value children (Genesis 1:28).
- Orthodox
- Follows halakhah fully: sex only within marriage; niddah and mikveh; modesty (tzniut), yichud and negiah; contraception only in defined circumstances (Yevamot 12b) and with rabbinic guidance; abortion only to protect the mother (Mishnah Oholot 7:6); homosexual acts forbidden (Leviticus 18:22), though many Orthodox communities stress compassion for gay Jews.
- Conservative (Masorti)
- Treats halakhah as binding but developing: in 2006 its law committee adopted a responsum lifting most restrictions on homosexual conduct and allowing gay and lesbian rabbis, alongside traditional responsa.
- Reform
- Treats halakhah as guidance, not binding law, emphasising ethical principles (love, fidelity, consent, equality); it accepts same-sex marriage and is more permissive on contraception and premarital relationships.
- Judgement
- Jewish sexual ethics are shared at the level of values (holiness, fidelity, consent, family) but divided on how binding traditional law is, which produces real differences on specific issues.
Marking (Original): 7 for a supported judgement, accurate positions of at least three movements, sources and terminology.
