Not to have sexual relations with a woman outside of marriage (harlotry)

#510 Negative commandment Deuteronomy 23:18

The cited verse

The Hebrew (Masoretic Text)

לֹא־תִהְיֶה קְדֵשָׁה מִבְּנוֹת יִשְׂרָאֵל וְלֹא־יִהְיֶה קָדֵשׁ מִבְּנֵי יִשְׂרָאֵל

In Maimonides’ words

How Maimonides defines this commandment in his Sefer HaMitzvot — his own words, shown as a primary source.

הזהיר שלא לבא על אשה בלא כתובה וקדושין, והוא אמרו לא תהיה קדשה מבנות ישראל. וכבר נכפלה האזהרה בזה הענין בלשון אחר, והוא אמרו אל תחלל את בתך להזנותה. ולשון (ספרי)[ספרא] אל תחלל את בתך להזנותה זה המוסר בתו פנויה שלא לשם אישות, וכן המוסרת עצמה שלא לשם אישות. ושמע ממני למה כפל לאו זה בזה הלשון ואיזה ענין נוסף בו, וזה שכבר קדם שהבא על הבתולה בין שיהיה מפתה או אונס שאין חייב שום עונש מן העונשין אלא קנס ממון ולקחת אותה כמו שהתבאר בכתוב, והיה עולה במחשבתנו שאחר שזה הדבר אין בו אלא קנס ממון שיהיה דינו כדין כל דבר שבממון, וכמו שיש רשות לאדם לתת לחבירו ממונו כמו שירצה ויפטרהו במה שיש לו אצלו, שיהיה לו כמו כן מותר שיקח בתו הנערה ויתננה לאיש שיבעל אותה ויפטרהו מזה, אחר שזה זכות מזכיותיו, רוצה לומר החמשים כסף שהם לאבי הנערה, או גם כן יתננה לו על תנאי שיקח ממנו כך וכך דינרים, על כן הזהיר מזה ואמר אל תחלל את בתך להזנותה, לפי שזה שדנתי לענשו ממון לבד, אמנם הוא כשיקרה שיפתנה איש או יאנוס אותה, אבל כשיהיה הענין ברצון שניהם יחד ובהסכמה אין דרך לזה. והראיה בזה הטעם באמרו לא תזנה הארץ ומלאה הארץ זמה, לפי שהפתוי והאונס לא יקרה אלא מעט אבל כשהיה הענין בבחירה והסכמה ירבה זה ויתפשט בארץ, וזה טעם יפה מאד ומשובח בזה הפסוק והוא נאות לכל מה שזכרוהו החכמים למה שהסכימו עליו הדינים התוריים. ועל זה הלאו דפנויה לוקין. והתבארו משפטי מצוה זו במקומות מיבמות. (כי תצא, נשים הלכות אישות):

He prohibited - not to have sexual intercourse with a woman without a contract (ketubah) and marriage (kiddushin). And that is His saying, "There shall be no harlot from the daughters of Israel" (Deuteronomy 23:18). And the prohibition of this content was already repeated with a different language; and that is His saying, "Do not profane your daughter to make her a harlot" (Leviticus 19:29). And the language of the [Sifra] (Sifra, Kedoshim, Chapter 7:2) is, "'Do not profane your daughter to make her a harlot' - that is one who gives over his single daughter, not for the sake of marriage; and, similarly, her giving herself over, not for the sake of marriage." And listen to me [as to] why this negative commandment was repeated with this language, and what content was added with it: And that is that He already preceded that one that has sexual intercourse with a virgin - whether it was seduction or whether it was rape - is not liable for any of the punishments, but rather for a monetary fine and to [have to] marry her, as is explained in Scripture. So it would enter our thoughts that since there is only a monetary fine, its law is like any monetary matter. So just like a person has the right to give his money to his fellow as he wants, and exempt him from [returning] anything that he has with him; it would likewise be permissible for him to take his maiden daughter and give her to a man for him to have sexual intercourse, and then exempt him from it - meaning to say, the fifty [measures of] silver which go to the father - given that this is one of his rights; or to also give her to him, on condition that he receive such and such dinars from him. That is why He prohibited this and said, "Do not profane your daughter to make her a harlot." For that which I judged to only punish him with money is in fact [only] when it happens that a man seduces her or rapes her. But that the matter be with the mutual consent of both of them and permissible, there is no way [for such a] thing! And the proof for this explanation is His saying [in the continuation of the verse], "lest the land fall into harlotry, and the land be filled with lewdness." For seduction and rape only occur a little, but if the matter were to be by choice and permissible, it would grow and spread in the land. And this explanation is very fine and praiseworthy regarding this verse; and it is fitting regarding all that the Sages mentioned and all that is in accordance with Torah laws. And we give lashes for this negative commandment of a single woman; and the regulations of this commandment have already been explained in various places in Yevamot. (See Parashat Ki Tetzeh; Mishneh Torah, Marriage.)

Applicability

How the catalog describes where and when this commandment applies. These are independent descriptions, not a verdict on which laws still count.

  • Recorded as practiced today

Classical halakhic consequences

The consequences the classical halakhah attaches to this commandment, grouped by who imposes them. Where a category has none recorded, that absence is itself meaningful.

Imposed by a court

  • Lashes (malkot)

At the hands of Heaven

No divinely-imposed consequence is recorded.

Ritual remedy

No ritual remedy is recorded.

How the streams of Judaism treat this commandment

The streams of Judaism read the same commandment differently — an ongoing plurality, not a ranking. Each position below is reported as the catalog records it; none is presented as the correct one.

  • Orthodox Binding
  • Conservative Binding, with modification
  • Reform Kept as an ethical principle
  • Reconstructionist Not binding
  • Karaite Binding

24 of 613 commandments have been examined in depth so far — this one is queued.

How later traditions received this commandment

How later traditions read or reworked this commandment, each attributed to its own voice. The catalog’s own classification of each reception is shown as it records it, never adopted as GEBible’s.

Qumran (the Dead Sea Scrolls)

  • CD 4:17-20 The catalog describes this reception as: thematic extension (zenut)
  • 11QTa (Temple Scroll) 57:17-19 read it more strictly

Rabbinic aggadah

  • Genesis Rabbah 85:8 expanded it homiletically

Philo of Alexandria

  • De Specialibus Legibus 3.51 rationalized it

Josephus

  • Antiquities 4.206 The catalog describes this reception as: paraphrase loosely tracks the adjacent prohibition on bringing a harlot's hire to the Temple (Deut 23:19) rather than v.18 directly

The New Testament

  • 1 Corinthians 6:9-18 The catalog describes this reception as: thematic extension porneia condemned; Pauline ethic of the body as temple — topical rather than direct reception of Deut 23:18
  • Hebrews 13:4 affirmed it marriage honored, fornicators judged

The Qur'an and hadith

  • Q 17:32 carried a parallel
  • Q 24:2-3 carried a parallel

Beside the older legal codes of its world

The commandment set beside the ancient Near-Eastern legal collections scholars compare it to — a descriptive comparison, not a claim of dependence.

  • code of hammurabi regulation of nadītu/šugītu cultic women's property and inheritance Relationship to the parallel: parallel with divergence §§178-182 Roth, Law Collections from Mesopotamia and Asia Minor, 2nd ed. (1997)
  • middle assyrian laws regulation of veiling distinctions among wives, concubines, harlots (harimtu), and qadištu-women Relationship to the parallel: shared theme A §40 Roth, Law Collections from Mesopotamia and Asia Minor, 2nd ed. (1997)

Where this commandment meets modern human-rights frameworks

One modern normative lens, attributed to it — not GEBible’s assessment. Each row names the framework it measures against and the catalog’s own classification of the relation.

This framework catalogues tensions; it records agreement in only one of its entries. The near-total tension rate is the shape of the instrument, not a finding.

  • general principle

    This framework classifies the relation as a direct contradiction.

    The commandment, as extended by the rabbinic tradition (Maimonides, Sefer HaMitzvot, Negative Commandment 355) to prohibit all extramarital sexual relations, criminalises consensual sexual conduct between adults who have not contracted a formal religious marriage; bodily-autonomy frameworks hold that competent adults have the right to engage in consensual sexual activity without religious or state prohibition.

  • Article 17

    This framework classifies the relation as a direct contradiction.

    ICCPR Article 17 protects individuals against arbitrary interference with their privacy, including sexual conduct; criminalising consensual adult extramarital sex with lashes constitutes an arbitrary and disproportionate interference with sexual privacy.

  • general principle

    This framework classifies the relation as an incompatible method.

    The prescribed penalty of thirty-nine lashes for extramarital relations constitutes corporal punishment, which modern criminal law universally prohibits as cruel and degrading.

  • Article 7

    This framework classifies the relation as an incompatible method.

    ICCPR Article 7 prohibits cruel, inhuman, or degrading treatment or punishment; flogging as the sanction for consensual extramarital sex constitutes degrading punishment under international human rights standards.

  • general principle

    This framework classifies the relation as abrogated in practice.

    Rabbinic tradition holds that the lashes sanction requires a functioning Sanhedrin, which has been inoperative since the Second Temple era; enforcement of the corporal penalty is thus suspended in practice, though the prohibition itself remains formally operative in Orthodox halakhah.

The enumeration counts this as a structural duplicate of commandment #470 — Structural duplicate of #470 — both cite Rambam SHM Negative 355 (Deuteronomy 23:18) with identical halakhic content. #470 is the canonical placement, integrated into the dataset's Chinukh-ordered marriage-law cluster (positive/negative pairings around #469–#483). #510–#515 form an isolated SHM-ordered run inserted into an otherwise Chinukh-ordered span. See task #93..
