Word Study

In depth

A plain-language study of pareisdýnō — the range of meaning it carries, how Scripture actually uses it, and where it points. Written for readers who don’t know the original language.

Core Meaning & Semantic Range

The Greek word pareisdýnō, represented by G3921, is defined as to settle in alongside, or to lodge stealthily. It appears 1 times across 1 unique verses in the Bible. The term specifically conveys the idea of a surreptitious, deceptive entry, with the verb itself being a compound that implies coming in from the side in a hidden manner.

Biblical Occurrences & Contextual Analysis

In its sole biblical appearance, G3921 is used to issue a severe warning about false teachers infiltrating the church. Jude describes how "certain men crept in unawares" Jude 1:4. The verse immediately characterizes these individuals as "ungodly men" who were destined for condemnation, and whose purpose is to corrupt the community by turning God's grace into licentiousness and denying Jesus Christ.

Related Words & Concepts

Several related words from its sole biblical context in Jude 1:4 illuminate the nature of this stealthy infiltration:

  • G765 asebḗs (irreverent, i.e. (by extension) impious or wicked:-- ungodly (man)): This word describes the fundamental character of those who "creep in unawares." These are the individuals for whom Christ died Romans 5:6 and against whom the law is directed 1 Timothy 1:9.
  • G766 asélgeia (licentiousness (sometimes including other vices):--filthy, lasciviousness, wantonness): This identifies the corrupting influence brought by the infiltrators, who turn grace into a license for immoral behavior. It is listed as one of the manifest works of the flesh Galatians 5:19.
  • G720 arnéomai (to contradict, i.e. disavow, reject, abnegate:--deny, refuse): This points to the ultimate doctrinal error of the false teachers. Their actions are a form of "denying" the Lord, which can be done through works Titus 1:16 or by professing a form of godliness while rejecting its power 2 Timothy 3:5.

Theological Significance

The theological weight of G3921 is concentrated in its single usage, providing a powerful warning against internal subversion.

  • Deceptive Infiltration: The word's core meaning emphasizes that the danger comes not from an open, external assault, but from a subtle, unnoticed entry of corrupting influences from within the community Jude 1:4.
  • Signs of Subversion: The men who "creep in unawares" are identified by their fruit: they are ungodly, they twist grace into lasciviousness, and they deny the authority of God and Jesus Christ Jude 1:4.
  • Divine Foreknowledge: The passage links this stealthy infiltration to divine judgment, noting that these men were "before of old ordained to this condemnation" Jude 1:4, showing that such corruption does not go unnoticed by God.

Summary

In summary, G3921 is a rare but vivid term that describes the insidious nature of false teaching. Though used only once, it encapsulates the danger of a threat that is subtle in its arrival but devastating in its effect. It serves as a permanent scriptural caution to be vigilant against those who would secretly introduce ungodliness, licentiousness, and a denial of the faith into the body of believers.
