Simon Peter therefore beckoned to him, that he should ask who it should be of whom he spoke.

Simon Peter, therefore, gave him a sign, and said to him, Who is it of whom He speaks?—Hence it is plain that Peter not only gave a sign to John by winking and nodding, as S. Augustine would have it, but also spoke to him quietly, as John here relates. Such is the opinion of Origen, Chrysostom, and Cyril. Peter asks this not as Prince of the Apostles (though Cyril takes this view), nor as though fearing, for himself lest he should be the traitor, as Chrysostom thinks, but out of his zeal, that he might avert so enormous a crime and prevent the betrayal of Christ, just as in the garden he wished to prevent His capture by cutting of the right ear of Malchus.
