rwp@Mark:14:54 @{Peter had followed him afar off} (\Hosea:Petros apo makrothen kolouthsen auti\). Here Mark uses the constative aorist (\kolouthsen\) where strkjv@Matthew:26:58|, and strkjv@Luke:22:54| have the picturesque imperfect (\kolouthei\), was following. Possibly Mark did not care to dwell on the picture of Peter furtively following at a distance, not bold enough to take an open stand with Christ as the Beloved Disciple did, and yet unable to remain away with the other disciples. {Was sitting with} (\n sunkathmenos\). Periphrastic imperfect middle, picturing Peter making himself at home with the officers (\hupretn\), under rowers, literally, then servants of any kind. strkjv@John:18:25| describes Peter as standing (\hests\). Probably he did now one, now the other, in his restless weary mood. {Warming himself in the light} (\thermainomenos prs to phs\). Direct middle. Fire has light as well as heat and it shone in Peter's face. He was not hidden as much as he supposed he was.
