John 18:25-27

Meanwhile, Simon Peter was still standing there warming himself. So they asked him, “You aren’t one of his disciples too, are you?” He denied it, saying, “I am not.” 26One of the high priest’s servants, a relative of the man whose ear Peter had cut off, challenged him, “Didn’t I see you with him in the garden?” 27Again Peter denied it, and at that moment a rooster began to crow.
