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.

This did not come into His mind then for the firsttime; but He was now about to make the traitor known, and single him out from the rest, and therefore was troubled in spirit. The traitor too was now just about to go forth to execute his purpose. He was troubled at the thought of His Passion being so near at hand, at the dangers to which His faithful followers would be brought at the hand of the traitor, which were even now impending over Him. Our Lord deigned to be troubled also, to show that false brethren cannot be cut off; even in the most urgent necessity, without the troubling of the Church. Hewas troubled not in flesh, but in spirit; for on occasion of scandals of this kind, the spirit is troubled, not perversely, but in love, lest in separating the tares, some of the wheat too be plucked up with them. But whether He was troubled by pity for perishing Judas, or, by the near approach of His own death, He was troubled not through weakness of mind, but power: He was not troubled because anything compelled Him, but He troubled Himself, as was said above. And in that He was troubled, He consoles the weak members of His body, i.e. His Church, that they may not think themselves reprobate, should they be troubled at the approach of death.
Away then with the reasonings of the Stoics, who deny that perturbation of mind can come upon a wise man; who, as they take vanity for truth, so make their healthy state of mind insensibility. It is good that the mind of the Christian may be perturbed, not by misery, but by pity. One of you, He said, i.e. one in respect of number, not of merit, in appearance not in virtue.
They had a devoted love for their Master but yet so that human weakness made them doubt of one another.
This is John, whose Gospel this is, as he afterwards declares. It is the custom of the sacred writers, when they come to any thing relating to themselves, to speak of themselves, as if they were speaking of another. For if the thing itself is related correctly, what does truth lose by the omission of boasting on the writer’s part? .
Observe too his mode of speaking, which was not by word, but by beckoning; Beckoned and spoke, i.e. spoke by beckoning. If even thoughts speak, as when it is said, They spoke among themselves, much more may beckonings, which are a kind of outward expression of our thoughts.
On Jesus’ breast; the same as in Jesus’ bosom. Or, he lay first in Jesus’ bosom, and then ascended higher, and lay upon His breast; as if, had he remained lying in His bosom, and not ascended to lie on His breast, our Lord would not have told him what Peter wanted to know. By his lying at last on Jesus 'breast, is expressed that greater and more abundant grace, which made him Jesus’ special disciple.
For by bosom what else is signified but secret? Here is the hollow of the breast, the secret’ chamber of wisdom.
Not as some careless readers think, that then Judas received singly Christ's body. For our Lord had already distributed the sacraments of His body and blood toall of them, while Judas was as there, as Luke relates; and after this He dipped the sop, as John relates, and gave it to the traitor; the dipping of the bread perhaps signifying the deep dye of his sin; for some dipping cannot be wasted out again; i.e. when things are dipped, in order to receive a permanent dye. If however this dipping meant anything good, he was as ungrateful for it, and deserved the damnation which followed him; And after the sop, Satan entered into him.
Or entered into him, that he might have more full possession of him: for he was in him, when he agreed with the Jews to betray, our Lord for a sum of money, according to Luke: Then entered Satan into Judas Iscariot, and he went away, and communed with the chief priests (Luke 22:3-4). In this state he came to the supper. But after the sop the devil entered, not to tempt him, as though he were independent, but to possess him as his own.
But some will say, was his being given up to the devil the effect of his receiving the sop from Christ? To whom we answer, that they may learn here the danger of receiving amiss what is in itself good. If he is reproved who does not discern,i.e. who does not distinguish, the Lord’s body from other food, how is he condemned who, feigning himself a friend, comes an enemy to the Lord’s table? .
He did not however enjoin the act, but foretold it, not from g desire for the destruction of the perfidious, but to hasten on the salvation of the faithful.
Our Lord then had bags, in which; He kept the oblations of the faithful, to supply the wants of His own followers, or the poor. Here is the first institution of ecclesiastical property. Our Lord shows that His commandment not to think of the morrow, does not mean that the Saints should never save money; but that they should not neglect the service of God for it, or let the fear of want tempt them to injustice.
