σπεῖρα

a cohort

Definition

The Greek word σπεῖρα (speira) primarily refers to a Roman military cohort, a tactical unit of soldiers. In the New Testament, it most often denotes a specific detachment of Roman troops, such as the cohort stationed in Jerusalem (John 18:3, 12) or the 'Italian Cohort' to which the centurion Cornelius belonged (Acts 10:1). In a more general sense, it can refer to a military guard or contingent, as seen when Paul is rescued from a mob by the commander of the cohort (Acts 21:31). The term is also used for the soldiers who escort prisoners, as with Paul's journey to Rome (Acts 27:1). In the Gospels, it specifically identifies the Roman soldiers who mock and crucify Jesus (Matthew 27:27, Mark 15:16).

Biblical Usage

Σπεῖρα is used seven times in the New Testament, appearing in the Gospels, Acts, and once in a historical narrative. Its usage consistently involves Roman military authority. In the Gospels (Matthew 27:27, Mark 15:16, John 18:3, 12), it refers to the soldiers directly involved in the arrest, mockery, and crucifixion of Jesus. In Acts, it describes specific Roman units: the 'Italian Cohort' of Cornelius (Acts 10:1), the troops who rescue Paul in Jerusalem (Acts 21:31), and the soldiers escorting Paul to Rome (Acts 27:1). The pattern shows it is a technical term for a Roman military formation, often highlighting moments of confrontation or transfer of custody between Jewish authorities and Roman power.

Etymology

The word σπεῖρα is a native Greek noun meaning 'anything wound or wrapped,' like a coil or twist. From this, it came to denote a body of men drawn up in a circle or a military unit. It was adopted as a loanword into Latin (as 'spira') and used by Greek writers to translate the Latin military term 'cohors' (cohort). In the Roman military system, a cohort was one-tenth of a legion, typically consisting of 480 to 600 soldiers. The New Testament usage directly reflects this borrowed, specialized military sense from the Roman imperial context.

Semantic Range

While σπεῖρα itself is a military term, its theological significance emerges from its narrative context. It underscores the concrete historical reality of Jesus's suffering under Roman authority, fulfilling prophecies of the Messiah's rejection by both Jewish and Gentile powers (Psalm 2:1-2). The presence of the cohort in the Passion narratives (e.g., John 18:3) highlights the cosmic scale of the conflict—the 'ruler of this world' employing imperial force against the Son of God. In Acts, the cohort becomes an instrument of divine providence, protecting Paul (Acts 21:31) and facilitating the spread of the gospel to Rome (Acts 27:1). Thus, the word reminds readers that God's redemptive plan unfolds within and sometimes through secular political and military structures.

In the 1st-century Roman world, a 'cohort' (σπεῖρα) was a standard military unit of about 480-600 men, one-tenth of a legion. Auxiliary cohorts, like the 'Italian Cohort' (Acts 10:1), were often stationed in provinces like Judea. This differs from a modern understanding of a vague 'group of soldiers'; it was a specific, organized force with a commander. In Jerusalem, a cohort was stationed at the Fortress Antonia to keep peace during festivals. Understanding this precise military context clarifies the scale of force sent to arrest Jesus (John 18:3) and the official Roman involvement in his execution, moving it beyond a mere Jewish religious dispute to an act of state power.

στρατιά (stratia, G4756) — A more general term for an army or host, often heavenly. λεγιών (legiōn, G3003) — A larger Roman legion, composed of ten cohorts. ἴλη (ilē, G2461) — A smaller troop or squadron, sometimes a cavalry unit.
