Matthew 26:58

All the disciples had fled and left Jesus (Matthew 26:56; cf. Mark 14:54; Luke 22:54; John 18:15-18), but Peter followed at a safe distance as Jesus’ guards led Him across the Kidron Valley, into Jerusalem, and into the high priest’s house. This house contained an open courtyard in the middle, which was typical. Peter positioned himself inconspicuously, he thought, near a fire in the courtyard to observe what would happen (cf. John 18:15-16). A church now stands over the traditional site on Mt. Zion: the church of St. Peter in Gallicantu, or St. Peter at the Crowing of the Cock.
