### Core Meaning & Semantic Range
The Greek word **seirá**, represented by `{{G4577}}`, refers to a **chain**. It appears only **1 time** in **1 unique verse** in the entire Bible. Its meaning is straightforward, denoting a chain used for binding or drawing, and its sole scriptural use is in a very specific and potent context of divine judgment.
### Biblical Occurrences & Contextual Analysis
The single biblical use of `{{G4577}}` is found in [[2 Peter 2:4]], which describes the fate of angels who sinned. In this passage, God "delivered them into **chains** of darkness, to be reserved unto judgment." The word here is not describing a physical, metallic chain but rather a means of confinement and bondage. It illustrates a state of being inescapably held in a condition described as darkness until a final judgment.
### Related Words & Concepts
Several related words from the context of [[2 Peter 2:4]] clarify the meaning of `{{G4577}}`:
* `{{G32}}` **ángelos** (angel): This word identifies the beings who are bound by these chains. Defined as "a messenger; especially an 'angel'," their status did not prevent them from judgment [[2 Peter 2:4]].
* `{{G264}}` **hamartánō** (to sin): This is the action that led to the angels being bound. It means "to miss the mark... to err, especially (morally) to sin," highlighting the transgression against God that warranted their confinement [[2 Peter 2:4]].
* `{{G2217}}` **zóphos** (darkness): This word is directly linked to `{{G4577}}` in the phrase "**chains** of darkness." It is defined as "gloom (as shrouding like a cloud)," indicating the nature of the confinement [[2 Peter 2:4]].
* `{{G5020}}` **tartaróō** (cast down to hell): This verb describes the action God took in binding the angels, meaning "to incarcerate in eternal torment." It is the act of consignment that places them into the chains of darkness [[2 Peter 2:4]].
### Theological Significance
The theological weight of `{{G4577}}` is concentrated in its single appearance.
* **Divine Retribution:** The use of **chains** demonstrates God's direct and decisive action against sin, even among powerful angelic beings. It is an instrument of divine penalty for rebellion.
* **Inescapable Confinement:** The imagery of "**chains** of darkness" suggests a complete and certain state of bondage. The angels are not merely punished but are actively restrained and held, unable to escape their sentence [[2 Peter 2:4]].
* **Reservation for Judgment:** The chains serve a specific purpose: to hold the angels "unto judgment" `{{G2920}}`. This shows that their current state is one of reservation for a future, final verdict, rather than being the final punishment itself [[2 Peter 2:4]].
### Summary
In summary, `{{G4577}}` is a term with a very narrow but powerful application in scripture. Its singular use to describe the "**chains** of darkness" binding sinful angels provides a vivid and sobering picture of divine authority and the inescapable consequences of sin. It functions as a key component in the biblical doctrine of judgment, illustrating how God restrains evil until its final reckoning.
