Mark 14:54

This notation helps the reader understand that Peter was in the high priest’s residence throughout Jesus’ trial there. It prepares us for the account of Peter’s denial (Mark 14:66-72) that happened while the Sanhedrin was examining Jesus. It also helps us appreciate the fact that Peter’s desertion of Jesus was only temporary. The synoptic evangelists did not mention that another disciple accompanied Peter into the courtyard (John 18:15). The officers would have been the temple police since the Roman soldiers would not have guarded the high priest’s palace.
