Luke 22:58

μετὰ βραχὺ, shortly after (here only in N.T.), while the mood of fear is still on him, no time to recover himself. ἕτερος, another of the attendants, a man. ἐξ αὐτῶν, of the notorious band, conceived possibly as a set of desperadoes. ἄνθρωπε, οὐκ εἰμί, man, I am not, with more emphasis and some irritation = denial of discipleship. In one sense a stronger form of denial, but in another a weaker. Peter might have known Jesus without being a disciple. To deny all knowledge was the strongest form of denial. Besides it was less cowardly to deny to a man than to a woman.
