John 18:16-17, 25-27

but Peter was standing at the door without. So the other disciple, who was known unto the high priest, went out and spake unto her that kept the door, and brought in Peter. The maid therefore that kept the door saith unto Peter, Art thou also one of this man’s disciples? He saith, I am not.

Now Simon Peter was standing and warming himself. They said therefore unto him, Art thou also one of his disciples? He denied, and said, I am not. One of the servants of the high priest, being a kinsman of him whose ear Peter cut off, saith, Did not I see thee in the garden with him? Peter therefore denied again: and straightway the cock crew.
