Johannes 18:16

But Peter stood at the door without--by preconcerted arrangement with his friend till he should get access for him. Then went out that other . . . and spake to her that kept the door, and brought in Peter--The naturalness of these small details is not unworthy of notice. This other disciple first made good his own entrance on the score of acquaintance with the high priest; this secured, he goes forth again, now as a privileged person, to make interest for Peter's admission. But thus our poor disciple is in the coils of the serpent. The next steps will best be seen by inverting Joh 18:17 and Joh 18:18.

Hitherto this evangelist has recorded little of the history of Christ, only so far as was requisite to introduce his discourses; but now that the time drew nigh that Jesus must die he is very particular in relating the circumstances of his sufferings, and some which the others had omitted, especially his sayings. So far were his followers from being ashamed of his cross, or endeavouring to conceal it, that this was what, both by word and writing, they were most industrious to proclaim, and gloried in it. This chapter relates, I. How Christ was arrested in the garden and surrendered himself a prisoner (Joh 18:1-12). II. How he was abused in the high priest's court, and how Peter, in the meantime, denied him (Joh 18:13-27). III. How he was prosecuted before Pilate, and examined by him, and put in election with Barabbas for the favour of the people, and lost it (Joh 18:28-40).

18:16-17 During Jesus’ interrogation by Annas (18:12-14, 19-24), the woman watching at the gate asked Peter if he was one of that man’s disciples. In contrast to Jesus, who stood up to his questioners and denied nothing, Peter quickly denied his link to Jesus three times (18:17, 25, 27).
