Word Study

In depth

A plain-language study of moichalís — 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 moichalís, represented by G3428, is a term for an adulteress. According to its base definition, it can be used to describe unfaithfulness in both a literal and a figurative sense. It appears 7 times across 6 unique verses in the Bible, making it a specific but impactful word for condemning marital or spiritual infidelity.

Biblical Occurrences & Contextual Analysis

In its literal application, G3428 defines a woman who is unfaithful to her marriage vows. Romans 7:3 states that if a woman is married to another man while her husband is still alive, "she shall be called an adulteress." However, the term is more frequently used figuratively to describe spiritual unfaithfulness. In both Matthew 12:39 and Matthew 16:4, the phrase "evil and adulterous generation" is used to rebuke those who demand signs instead of exercising faith. This figurative sense is also present in James 4:4, which equates friendship with the world to spiritual adultery against God.

Related Words & Concepts

Several related words help clarify the context and severity of being an adulteress:

  • G3432 moichós (adulterer): This is the direct male counterpart, meaning "a (male) paramour; figuratively, apostate." It is used alongside G3428 in James 4:4 to address both "adulterers and adulteresses."
  • G268 hamartōlós (sinful, i.e. a sinner): This word is paired with G3428 in Mark 8:38 to describe "this adulterous and sinful generation," linking spiritual infidelity directly to a state of sin.
  • G4190 ponērós (hurtful, i.e. evil): This term is used to describe the character of the "wicked and adulterous generation" in Matthew 16:4, emphasizing the malevolent nature of their unfaithfulness.
  • G266 hamartía (a sin): In 2 Peter 2:14, having "eyes full of adultery" G3428 is connected to an inability to cease from sin, highlighting the perpetual nature of this transgression.

Theological Significance

The theological weight of G3428 is centered on the concept of covenant relationship and faithfulness.

  • Literal Covenant Breaking: The word's use in Romans 7:3 establishes a baseline understanding of adultery as a violation of the sacred marriage covenant.
  • Spiritual Apostasy: The term is elevated to a spiritual metaphor, portraying Israel's or humanity's unfaithfulness to God as a form of adultery. The "adulterous generation" Matthew 12:39 is one that has broken its covenant with God.
  • Enmity with God: James 4:4 provides a stark theological definition, framing "friendship of the world" as an act of spiritual adultery that makes one an enemy of God.
  • Internal Corruption: The description in 2 Peter 2:14 of having "eyes full of adultery" connects this unfaithfulness to an internal state of corruption, linked to covetousness G4124 and an inability to cease from sin G266.

Summary

In summary, G3428 moichalís moves beyond a simple label for an unfaithful woman. While it holds a literal meaning within the context of marriage law, its primary biblical function is as a powerful metaphor for spiritual betrayal. It is used to condemn a generation's lack of faith, to define worldliness as a violation of one's relationship with God, and to characterize a heart that is fundamentally wicked and sinful.
