In the Hebrew legal system, the task of law enforcement—as evidenced in biblical accounts—mainly fell upon the witnesses of the crime. They would seize the wrongdoer at the scene, escort him to the court, and serve as his accusers. However, there must have existed actual officers of the court, a group assigned to implement its mandates, including capturing criminals and presenting them before the judiciary. This function would certainly be invoked when a murderer sought refuge in one of the cities designated for protection, and also if the witnesses were unable to detain the offender for any reason. It is not hard to infer which approach the chief priests might have opted for in this scenario. With no witnesses to testify against Jesus, the entire multitude of the Sanhedrin's personnel—including those who had tortured criminals before their execution—was at the high priest’s disposal, ripe for Caiaphas to utilize.
Perhaps, genuinely apprehensive of the one he was confronting and wishing to imbue the proceedings with added weight, Caiaphas ordered the seizure of Jesus by a detachment of Roman soldiers, referred to as a "spira" along with a captain or tribune leading them. Jerusalem, during Christ’s ministry, was under Roman control, and the decree of the Roman governor was absolute. Six cohorts of Roman soldiers were ever-present, with one specifically stationed at Antonia to monitor Jewish behavior during significant festivals. This cohort is mentioned by the Evangelist John, although his term "spira" does not imply the entirety; only a fraction was placed at the disposal of the high priest. A cohort typically consisted of about 500 to 600 soldiers, a number excessive for arresting just one individual. Moreover, Roman troops were joined by the Sanhedrin’s guards and servants from the chief priests and Pharisees, who did not bear the formal title of "shotaer." Alongside them were also ‘the chief priests and rulers of the temple and elders,’ which indicates the considerable size of the crowd armed with swords and clubs, led by Judas.
Familiarity with the titles of chief priests and elders reveals the array of authority present that day. Regarding the 'captains of the temple,' parallels between scriptural mentions and writings of Josephus Flavius provide insight into their roles. Luke distinguishes these magistrates from the chief priests, while the other Gospels often group them under that title. The position of the temple captain was one of significant importance, empowered with recognized authority and connections to the Sanhedrin. Historical records show that one such captain, named Ananus, was situated next to the high priest Ananias. It is also noted that the captain had primary oversight in temple courts and the authority to secure the gates of the sanctuary. Thus, we recognize the term ‘lord of the temple mount’ mentioned by Talmudic scholars, a position responsible for overseeing the individual temple guards who answered to him and whose immediate superiors shared the title of captain. It is likely that Luke identified these leaders among the assembly in the garden of Gethsemane, standing with the chief priests and elders of the people.
