John 18:25-27

25Now Simon Peter was [still] standing and warming himself. So they said to him, “You are not one of His disciples, are you?” He denied it and said, “I am not.”

26One of the high priest’s servants, a relative of the one whose ear Peter cut off, said, “Did I not see you with Him in the garden?”

27So Peter denied it again, and immediately a rooster crowed.
