John 18:25-27 - Peter Denies Jesus The Second And Third Times
25 But Simon Peter still stood warming himself. So they said to him, "Are you also one of his disciples?" He denied it and said, "No, I am not."
26 One of the high priest's slaves, a relative of the man whose ear Peter had cut off, said, "Did I not see you with him in the garden?"
27 Peter again denied it, and at that moment a cock crowed.
