John 18:15-18, 25-27
Simon Peter followed Jesus, and so did another disciple. As this disciple was known to the high priest, he entered the court of the high priest along with Jesus, while Peter stood outside at the door. So the other disciple, who was known to the high priest, went out and spoke to the maid who kept the door, and brought Peter in.
The maid who kept the door said to Peter, "Are not you also one of this man's disciples?" He said, "I am not."
Now the servants and officers had made a charcoal fire, because it was cold, and they were standing and warming themselves; Peter also was with them, standing and warming himself.
-----
Now Simon Peter was standing and warming himself. They said to him, "Are not you also one of his disciples?" He denied it and said, "I am not."
One of the servants of the high priest, a kinsman of the man whose ear Peter had cut off, asked, "Did I not see you in the garden with him?" Peter again denied it; and at once the cock crowed.
