Word Study

In depth

A plain-language study of phéngos — 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 phéngos, represented by G5338, denotes brilliancy or light. It appears 3 times across 3 unique verses in the Bible. This term is used to describe both the light from celestial bodies and the illumination from a man-made source like a lamp.

Biblical Occurrences & Contextual Analysis

In scripture, G5338 appears in two distinct contexts. It is used twice to describe the eschatological dimming of the heavens, where "the moon shall not give her light" as a sign of tribulation (Matthew 24:29; Mark 13:24). In a different context, it refers to the light of a candle, which is placed on a candlestick so that people who enter may see the light Luke 11:33.

Related Words & Concepts

Several related words help define the context for G5338:

  • G4582 selḗnē (the moon): This is the celestial body whose light (phéngos) is said to fail during the tribulation Matthew 24:29. The moon and sun are often mentioned together in passages describing cosmic signs Luke 21:25.
  • G3088 lýchnos (a portable lamp): This is the source of the light (phéngos) in the parable from Luke. This word can be used literally or figuratively, such as when the Lamb is described as the light of the city Revelation 21:23.
  • G4654 skotízō (to obscure): This verb is used to describe what happens to the sun when the moon fails to give its light. In prophetic passages, celestial bodies are darkened, signifying a divine event Mark 13:24.
  • G681 háptō (to set on fire): This verb describes the action taken to produce the light in Luke's parable, where a man has lighted a candle Luke 11:33.

Theological Significance

The theological weight of G5338 is demonstrated in its specific applications.

  • Cosmic Signs: The absence of light (phéngos) from the moon serves as a divine sign of the end times and tribulation. This links the word to prophecies concerning the shaking of the heavens (Matthew 24:29; Mark 13:24).
  • Purposeful Illumination: In the parable of the candle, the light is intended to be seen and provide guidance. The act of lighting G681 a candle G3088 is done specifically so people may see the light G5338, implying that truth is not meant to be hidden Luke 11:33.
  • Light versus Obscurity: The word exists in a direct relationship with the concept of being darkened G4654. The light from the sun is obscured, and the light G5338 from the moon fails, signifying a great disruption of the created order Mark 13:24.

Summary

In summary, G5338 provides a specific term for brilliancy. Though used infrequently, it is applied significantly to both the vast light of the moon and the focused light of a single candle. It carries theological weight by illustrating concepts of eschatological signs and the essential visibility of that which is meant to illuminate.
