Peter denied two more times that he knew Jesus.

John 18:25-27

25 As Simon Peter was standing warming himself at the fire, someone else said to him, “You are not one of that man’s disciples, are you?” He denied that he was, and said, “I am not.” 26 Later one of the high priest’s servants, a man who was a relative of the man whose ear Peter had cut off before, said to him, “I saw you with that man in the grove of olive trees, did I not?” 27 Peter again denied it. Immediately a rooster crowed, as Jesus had said would happen.
