The English word has two generic meanings, each shading off into several specific meanings: (1) that which holds together, binds or encircles: a bond; (2) a company of men. The second sense may philologically and logically have been derived from the first, men being held together by social ties. Both meanings appear in Old Testament and New Testament representing various Hebrew and Greek words.
(3) The Augustan Band (σπεῖÏα ΣεβαστηÌ, speıÌra SebasteÌ„Ì) to which Julius, the Roman centurion who had charge of Paul as a prisoner on his voyage to Rome, belonged, was a cohort apparently stationed at Caesarea at the time (). Schürer (GJV, I3, 461 f) is of opinion that it was one of five cohorts mentioned by Josephus, recruited in Samaria and called Sebastenes from the Greek name of the city of Samaria (Sebaste). This particular cohort had in all likelihood for its full name Cohors Augusta Sebastenorum, Augusta being an honorific title of which examples are found in the case of auxiliary troops. Sir William Ramsay, following Mommsen (St. Paul the Traveler, 315, 348), thinks it denotes a body of legionary centurions, selected from legions serving abroad, who were employed by the emperor on confidential business between the provinces and Rome, the title Augustan being conferred upon them as a mark of favor and distinction. The grounds on which the views of Mommsen and Ramsay rest are questioned by Professor Zahn (Introduction to the New Testament, I, 551ff), and more evidence is needed to establish them. See ARMY, ROMAN.
(4) The Italian Band (σπεῖÏα ἰταλικηÌ, speıÌra ItalikeÌ„Ì) was a cohort composed of volunteer Roman citizens born in Italy and stationed at Caesarea at this time (). Schürer maintains that there could have been no Roman cohort there at this time, although he accepts the testimony of inscriptions to the presence of an Italian cohort at a later time. He accordingly rejects the story of Cornelius, holding that the author of the Acts has given in this narrative conditions belonging to a later time (GJV, I3, 462 f). In reply to Schürer, Blass asks why one of the five cohorts mentioned by Josephus may not have been composed of Roman citizens living at Caesarea or Sebaste, and bearing this name (Blass, Acta Apostolorum, 124). From a recently discovered inscription, Sir W. M. Ramsay has ascertained that there was an Italian cohort stationed in Syria in 69 ad, which heightens the probability of one actually being found in Caesarea at 41-44 ad, and he shows that even if his cohort was at the time on duty elsewhere a centurion like Cornelius might well have been at Caesarea at the time mentioned (Expositor, 5th series, IV, V, with Schürer's rejoinder). The subject of detached service in the provinces of the Roman Empire is admittedly obscure, but nothing emerges in this discussion to cast doubt upon the historical character of Luke's narrative.
