Catena Aurea on John 13:21–30: John Chrysostom

Whom Jesus loved. This John says to shew his own innocence, and also why it was that Peter beckoned to him, inasmuch as he was not Peter’s superior: Simon Peter therefore beckoned to him, that he should ask who it should be of whom he spake. Peter had been just reproved, and therefore, checking the customary vehemence of his love, he did not speak himself now, but made John speak for him. He always appears in Scripture as zealous, and an intimate friend of John’s.
