Bible Question:

What is the meaning of the Greek word porneia in the Bible?

Bible Answer:

The Greek word porneia occurs 25 times in 24 verses in the New Testament. The word appears for the first time in the New Testament in Matthew 5:32.

. . . but I say to you that everyone who  divorces his wife, except for the reason of unchastity, makes her commit adultery; and whoever marries a divorced woman commits adultery. Matthew 5:32 (NASB)

The word porneia is translated differently in different Bibles. For example, in the New American Standard Bible (NASB) the word porneia is translated as “unchastity.” The King James Version translates the word porneia as “fornication.” The New International Version (NIV), NET Bible and English Standard Bible (ESV) translate porneia as “immorality.” The New Living Translation (NLT) translates the word as “unfaithful” and, unfortunately, misses the meaning of porneia.

Porneia Definition

The Porneia Definition – Greek Lexicons

Now we will discover what the Greek dictionaries say porneia means. A Greek dictionary is called a Greek lexicon. We will examine a number of lexicons so that the reader can see they are in agreement even though the wording may be slightly different. But first, we will start with an overview.

The original meaning of the Greek word porneia is “to prostitute” or “to sell.” However by the time of the New Testament, porneia had a very broad meaning that included sexual behavior such as prostitution, extramarital sexual intercourse or adultery, paedophilia, promiscuity, homosexuality, lesbianism, incest, premarital sex and bestiality. The Exegetical Dictionary of the New Testament states,

Πορνεία means “prostitution, unchastity, fornication,” and is used “of every kind of unlawful sexual intercourse” (BAGD s.v.). . . . Since in Rom. 1:26f. Paul clearly alludes to homosexuality as sexual immorality, πορνεία can also refer to homosexuality as sexual immorality, as does εκπορνεύω. in Jude 7 (cf. Genesis 19) [1]

The lexicon’s message is not that porneia occurs in Romans 1:26f, but that the sexual sin in Romans 1 is included in porneia. For more discussion about Jude 7, see below.

Kittel, Bromiley and Friedrich  provides a very complete meaning of porneia stating that its meaning includes “adultery, fornication, licentiousness, and homosexuality.”[2, 3] Harper’s Bible Dictionary states that porneia also includes “bestiality.”[4]

Colin Brown states this about porneia,

porneia (Dem.  onwards, rare in cl. Gk) harlotry, unchastity (also of a homosexual nature).[5]

This highly acclaimed Greek-English dictionary points out that porneuo, pornos, and porneia are part of the same word group. Then it states,

The word group can describe various extra-marital sexual modes of behavior insofar as they deviate from accepted social and religious norms (e.g. homosexuality, promiscuity, paedophilia, and especially prostitution).[6]

Colin Brown also tell us that porneia occurs in the “Testament of Benjamin.” The word is used to refer to homosexual behavior. In the following quote from the “Testament of Benjamin,” porneia is translated as fornication. Yet, it is referring to homosexual activity since Jude 7 is about homosexuality.

And  believe that there will be also evildoings among you, from the words of Enoch the righteous: that ye shall commit fornication with the fornication of Sodom . . . [7]

Verein D. Verbrugge in the  New International Dictionary of New Testament Theology writes . . .

Rab. Jud. frowned on any kind of prostitution or extramarital sexual intercourse. Incest and all kinds of unnatural sexual intercourse were viewed as porneia. [8]

How Porneia Is Used In the New Testament

1 Corinthians 7:2 makes it clear that porneia refers to sexual intercourse and sexual activity.

But because of immoralities, each man should have relations with his own wife and each woman with her own husband.  1 Corinthians 7:2 (NASB)

The word “immoralities” in this verse is translated from porneia. This helps us understand that porneia refers to some form of sexual activity, including sexual intercourse.  The following chart shows us how porneia is used in the New Testament and helps us understand the breadth of the meaning of porneia (read preceding comments supporting footnotes).

Various Meanings of Porneia

Greek Word For Fornication In KJV Bible

The porneia definition includes sexual activity outside of marriage. The King James Version Bible (KJV) translates porneia extensively as fornication as well as older authors. But in recent history, the word fornication only refers to sexual activity prior to marriage. Therefore, more recent Bibles such as the English Standard Version (ESV) do not include the word fornication. The ESV translates porneia as immoralities or immorality. It avoids translating porneia as fornication. Consider  Matthew 19:9.

And I say to you: whoever divorces his wife, except for sexual immorality, and marries another, commits adultery.” Matthew 19:9 (ESV)

In this verse, the word immorality is translated from porneia and the word adultery is translated from moicheuo. The Greek word for adultery is moicheuo. This helps us understand why porneia was translated as fornication but that is not correct in modern times. That is on occasion, porneia is the Greek word for fornication in the King James Version Bible but not in modern Bibles. Today, porneia refers to any sexual activity, except for fornication. Fornication exclusively refers to sexual activity before marriage.

It should be noted that the Greek word for “indulged” in Jude 7 is ekporneuo.

Just as Sodom and Gomorrah and the cities around them, since they in the same way as these indulged in gross immorality and went after strange flesh, are exhibited as an example in undergoing the punishment of eternal fire. Jude 7-8 (NASB)

Ekporneuo and porneia are from the same word group. Ekporneuo is the verb form of porneia, and ek adds emphasis. That is, ekporneuo and porneia share the same root meaning. Ekporneuo is a verb and porneia is the noun form. That is, ekporneuo helps us understand that porneia includes homosexuality. Porneia refers to a wide range of sexual sins.


Every sexual sin is repugnant to God. The Greek word porneia is a sin that includes a wide range of illicit sexual intercourse or sexual activity. The word can refer to prostitution, sexual intercourse outside of marriage, pedophilia, promiscuity, homosexuality, lesbianism, incest, premarital sex and bestiality.
