When Jesus had thus said, he was troubled in spirit, and testified, and said,
Verily, verily, I say unto you, that one of you shall betray me.
All Commentaries on John 13:21 Go To John 13
John Chrysostom
AD 407
Our Lord after His twofold promise of assistance to the Apostles in their future labors, remembers that the traitor is cut off from both, and is troubled at the thought: When Jesus had thus said, He was troubled in spirit, and testified, and said, Verily, verily, I say to you, that one of you shall betray Me.
As He did not mention Him by name, all began to fear: Then the disciples looked one on another, doubting of whom He spoke; not conscious of any evil in themselves, and entrusting to Christ’s words, more than to their own thoughts.
While all were trembling, and not excepting even Peter, their head, John, as the beloved disciple, lay upon Jesus’ breast. He then lying on Jesus’ breast said to Him, Lord, who is it? .
If you want to know the cause of this familiarity, it is love: Whom Jesus loved. Others were loved, but hewas loved more than any.
Whom Jesus loved. This John says to show 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 spoke. 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.
But not even then did our Lord expose the traitor by name; Jesus answered, He it is, to whom I shall give a sop when I have dipped it. Such a mode of declaring him, should itself have turned him from his purpose. Even if a partaking of the same table did not shame him, a partaking of the same bread might have. And when He had dipped the sop, He gave it to Judas Iscariot, the son of Simon.
So long as he was one of the twelve, the devil did not dare to force an entrance into him; but when he was pointed out, and expelled, then he easily leaped into him.
That which you do, do quickly, is not a command, or arecommendation, but a reproof, meant to show too that He was not going to offer any hindrance to His betrayal. Now no man at the table knew for what intent He spoke this to him. It is not easy to see, when the disciples had asked, Who is he, and He had replied, He itis to whom I shall give a sop, how it was that they did not understand Him; unless it was that He spoke too low to be heard; and that John lay upon His breast, when he asked the question, for that very reason, i.e. that the traitor might not be made known. For had Christ made him known, perhaps Peter would have killed him. So it was then, that none at the table knew what our Lord meant. But why not John? Because he could not conceive how a disciple could fall into such wickedness: he was far from such wickedness himself, and therefore did not suspectit of others. What they thought He meant we are told in what follows: For some of them thought, because Judas had the bag, that Jesus had said to him, Buy those things that we haveneed of against the feast, or, that he should give something to the poor.
None of the disciples contributed this money, but it is hinted that it was certain women, who, it is said, ministered to Him of their means. But how was it that He Who forbade scrip, and staff, and money, carried bags for the relief of the poor? It was to show you, that even the very poor, those who are crucified to this world, ought to attend to this duty. He did many things in order to instruct us in our duty.
It follows: And it was night, to show the impetuosity of Judas, in persisting in spite of the unseasonableness of the hour.
