John 18:25-27

25 Now Simon Peter was standing and warming himself. They asked him, "You are not also one of his disciples, are you?" He denied it and said, "I am not."
26 One of the slaves of the high priest, a relative of the man whose ear Peter had cut off, asked, "Did I not see you in the garden with him?"
27 Again Peter denied it, and at that moment the cock crowed.
