Topical Lexicon
Word Family and Conceptual Background

The term σειρά carries the picture of a woven strand strong enough to bind. Whether fashioned from flax, hemp, leather, or metal, it points to something that restrains — a rope, cord, or chain. Throughout Scripture, cords symbolize both slavery and salvation: what holds fast can imprison or secure, depending on who wields it.

Old Testament Parallels

The Septuagint repeatedly uses σειρά to translate Hebrew words for rope or cord. Notable scenes include:
Judges 16:11 — Delilah binds Samson “with new ropes” (LXX σειραί) to sap his strength.
Psalm 129:4 — “The LORD has broken the cords of the wicked,” a declaration of covenant deliverance.
Job 38:31 — “Can you bind the chains of the Pleiades?” God challenges Job, contrasting human frailty with divine power.

In each setting, σειρά frames the tension between human limitation and divine intervention. Either God cuts the cords to liberate, or He tightens them in judgment.

Historical and Cultural Setting

In the Greco-Roman world, ropes and chains served everyday tasks: securing cargo, restraining prisoners, even adorning temples. To Jewish ears steeped in Exodus imagery, cords evoked slavery in Egypt; to Gentile believers, they hinted at Roman imprisonment. Both audiences grasped the sober weight of being bound.

New Testament Usage (2 Peter 2:4)

“For if God did not spare angels when they sinned, but cast them into hell, delivering them in chains of darkness to be held for judgment” (2 Peter 2:4).

Here σειραῖς depicts a current, conscious confinement of fallen angels pending final judgment. Peter anchors his warning to the churches: if celestial beings could not evade accountability, neither will false teachers (2 Peter 2:1-3). The imagery heightens the certainty and severity of divine justice.

Theological Significance

1. Judicial Restraint: σειρά underscores that judgment is not merely future but actively enforced. Spiritual rebels are already confined.
2. Moral Gravity: Binding language deepens the seriousness of sin; rebellion warrants real restraint, not merely metaphorical censure.
3. Sovereign Authority: Only God can forge and break such chains. His sovereignty secures believers (Jude 24) and confines demons (Luke 8:31).
4. Eschatological Assurance: The present incarceration of fallen angels guarantees a climactic reckoning for all evil powers (Revelation 20:10).

Implications for Christian Ministry

• Warning against Presumption: Teachers who distort truth risk the same fate as the bound angels. Faithful exposition guards congregations from destructive heresies.
• Pastoral Comfort: Saints facing persecution can recall that even hostile spiritual forces already wear God-forged chains; their power is limited.
• Evangelistic Urgency: The reality of bondage and judgment calls sinners to embrace the One who breaks chains (Romans 6:22).
• Spiritual Warfare Perspective: Prayer and proclamation operate from victory, not fear, because opposing powers are restrained until their final sentence.

Summary

Strong’s Greek 4577 (σειρά) appears only once in the Greek New Testament, yet its rich Old Testament background and vivid eschatological setting make it a powerful emblem of judgment and deliverance. Whether illustrating divine restraint of rebel angels or celebrating the Lord’s liberation of His people, σειρά reminds believers that God alone binds and looses, and His verdict is both present and future, sure and final.
