And Peter followed him afar off, even into the palace of the high priest: and he sat with the servants, and warmed himself at the fire. Peter followed - On Peter's denial, see Matthew 26:57, etc.
At the fire - Προς το φως, literally, at the light, i.e. a fire that cast considerable light, in consequence of which, the maid servant was the better able to distinguish him: see Mark 14:67.
