John 13:21-30

Verse 21

Was troubled in spirit - See the note on Joh 11:33.

And testified - Spoke with great earnestness.

Shall betray me - Παραδωσει με, Will deliver me up. Judas had already betrayed our blessed Lord, and he was now on the point of delivering him up into the hands of the chief priests. By all these warnings, did not our Lord intend that Judas should be benefited? - that he should repent of his iniquity, and turn and find mercy?
Verse 22

Looked one on another doubting of whom he spake - See the notes on Mat 26:20-25 (note). Every one but Judas, conscious of his own innocence, looked about upon all the rest, wondering who in that company could be such a traitor! Even Judas himself is not suspected. Is not this a proof that his general conduct had been such as to subject him to no suspicion?
Verse 23

Now there was leaning on Jesus' bosom - The Jews of those days, at their suppers, reclined, supported by their left arm, on couches placed round the table, as the Greeks and Romans did. On each couch there were two or three persons; and the head of one of them came near to the bosom of him who reclined above him on the same couch. The person here mentioned was John, the writer of this history, who, being more tenderly loved by Christ than the rest, had always that place at table which was nearest to his Lord.
Verse 25

He then lying on Jesus' breast - Επιπεσων, laying his head against the breast of Christ, in a loving, respectful manner. As the expressions in the text are different here from those in the preceding verse, it shows that John altered his position at table, in order to ask the question which Peter suggested, which he probably did by whispering to our Lord; for, from Joh 13:28, we may learn that the other disciples had not heard what John said; and it is likely that the following words - It is he to whom I shall give the morsel when I have dipped it, were whispered back by Christ to John.
Verse 26

And when he had dipped the sop - Dr. Lightfoot observes that it was no unusual thing to dip a sop and give it to any person; and it is probable that the rest of the disciples considered it as given to Judas that he might hurry to do some work on which he wished to employ him, and not wait to finish his supper in a regular manner. They did not hear the question that John asked, nor our Lord's answer; but they no doubt heard the words, That thou doest do quickly - and might understand them as above.
Verse 27

Satan entered into him - He had entered into him before, and now he enters again, to strengthen him in his purpose of delivering up his Master. But the morsel was not the cause of this entering in; the giving of it only marks the time in which the devil confirmed Judas in his traitorous purpose. Some have thought that this morsel was the sacrament of the Lord's Supper: but this is an utter mistake.

That thou doest, do quickly - As if he had said: "Thou art past all counsel; thou hast filled up the measure of thy iniquity, and hast wholly abandoned thyself to Satan; I will not force thee to turn from thy purpose, and without this thou wilt not. Thy designs are all known to me; what thou art determined to do, and I to permit, do directly; delay not, I am ready."
Verse 29

Buy those things that we have need of against the feast - Calmet's observation here has weight so it. "The disciples who thought that our Lord had said this to Judas, knew well that on the day of the passover there was neither buying nor selling in Jerusalem. This, therefore, did not happen on the paschal evening; for the feast, according to the common opinion, must have begun the preceding evening, and Jesus have eaten the passover with his disciples the night before his death; but it appears to me, by the whole text of St. John, that the passover did not begin till the time in which our Lord expired upon the cross. It was then that they were sacrificing the paschal lambs in the temple. It is therefore probable that the apostles believed that Judas went to purchase a lamb, and the other necessary things for the evening, and for the day of the Passover." On this subject the reader is requested to consult the observations at the end of Matthew 26, where the subject is considered at large.

Give something to the poor - It is well known that our Lord and his disciples lived on public charity; and yet they gave alms out of what they had thus received. From this we learn that even those who live on charity themselves are expected to divide a little with those who are in deeper distress and want.
Verse 30

He - went immediately out: and it was night - He set off to Jerusalem from Bethany, which was about two miles distant; and, under the conduct of the prince of darkness, and in the time of darkness, he did this work of darkness.
