A.T. Robertson Commentary John 18:17

"The maid therefore that kept the door saith unto Peter, Art thou also [one] of this man`s disciples? He saith, I am not." — John 18:17 (ASV)

The maid (η παιδισκη). Feminine form of παιδισκος, diminutive of παις. See Mt 26:69. When "the maid the portress" (apposition).

Art thou also? (μη κα συ ει; ). Expecting the negative answer, though she really believed he was.

This man's (του ανθρωπου τουτου). Contemptuous use of ουτος with a gesture toward Jesus. She made it easy for Peter to say no.
