"All this imagery becomes doubly forcible if we remember that when St. Paul wrote the words he was chained to a soldier, and in the close neighbourhood of military sights and sounds. The appearance of the Prætorian Guards was daily familiar to him; as his 'chains,' on the other hand (so he tells us in the succeeding Epistle), became well known throughout the whole _Prætorium_! (Phil. i. 13). A difference of opinion has existed as to the precise meaning of the word in this passage. Some have identified it, as in the authorised version, with the house of Cæsar on the Palatine: more commonly it has been supposed to mean that permanent camp of the Prætorian Guards, which Tiberius established on the north of the city, outside the walls. As regards the former opinion, it is true that the word came to be used, almost as we use the word 'palace,' for royal residences generally or for any residences of princely splendour. Yet we never find the word employed for the imperial house at Rome: and we believe the truer view to be that which has been recently advocated, namely, that it denotes here, not the palace itself, but the quarters of that part of the imperial guards, which was in immediate attendance upon the emperor. The emperor was _prætor_ or commander-in-chief of the troops, and it was natural that his immediate guard should be in _prætorium_ near him. It might, indeed, be argued that this military establishment on the Palatine would cease to be necessary, when the Prætorian camp was established: but the purpose of that establishment was to concentrate near the city those cohorts, which had previously been dispersed in other parts of Italy: a local body-guard near the palace would not cease to be necessary: and Josephus, in his account of the imprisonment of Agrippa, speaks of a 'camp' in connection with the 'royal house.' Such we conceive to have been the barrack immediately alluded to by St. Paul: though the connection of these smaller quarters with the general camp was such that he would naturally become known to '_all the rest_' of the guards, as well as those who might for the time be connected with the imperial household. "St. Paul tells us (in the Epistle to the Philippians) that throughout the Prætorian quarter he was well known as a prisoner for the cause of Christ, and he sends special salutations to the Philippian Church from the Christians of the imperial household. These notices bring before us very vividly the moral contrasts by which the Apostle was surrounded. The soldier to whom he was chained to-day might have been in Nero's body-guard yesterday; his comrade who next relieved guard might have been one of the executioners of Octavia, and might have carried her head to Poppæa a few weeks before.
