Then the disciples looked one on another, doubting of whom he spake.

the disciples were looking, therefore, one at another, doubting concerning whom he speaketh.

The disciples began looking at one another, at a loss to know to which of them He was referring.

Then the eyes of the disciples were turned on one another, in doubt as to whom he had in mind.

Therefore, the disciples looked around at one another, uncertain about whom he spoke.

The disciples looked at one another, wondering whom he meant.

The disciples, therefore, looked on one another. They who are not conscious of any crime are rendered uneasy by what Christ has said: Judas alone is so stupid amidst his malice, that he remains unmoved. The authority of Christ was held in so great estimation by the disciples, that they were fully convinced that he said nothing without a good reason; but Satan had expelled from the heart of Judas all reverence, so that it was harder than a rock to reject every admonition. And though Christ appears to be somewhat unkind in inflicting this torture, for a time, on those who were innocent, yet as anxiety of this kind was profitable to them, Christ did them no injury. It is proper that, when the children of God have heard the sentence of the ungodly, they should themselves feel uneasiness, that they may sift themselves, and guard against hypocrisy; for this gives them an opportunity of examining themselves and their life. This passage shows that we ought sometimes to reprove the ungodly in such a manner as not instantly to point the finger to them, until God, by his own hand, drag them forth to the light. For it frequently happens that there are secret diseases in the Church, which we are not at liberty to disguise; and yet the wickedness of men is not so ripe as to be capable of being laid open. In such cases we ought to take this middle path.

Doubting of whom - The word translated "doubting" denotes that kind of anxiety which a man feels when he is in perplexity, and knows not what to say or do. We should say they were at a loss. See the notes at Matthew 26:22.

Looked one on another doubting of whom he spake - See the notes on Matthew 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?

Then the disciples looked one to another,.... As persons surprised and astonished, and as scarce crediting what was said; not having had the least suspicion of anyone among them, that could be guilty of such an action; and expressing by their looks their detestation of, and indignation at so horrible an iniquity; or they looked one to another, to observe if they could, whether the countenance of anyone would discover who the person was:
doubting of whom he spake; not being able to conceive and imagine, who the person was he had in view; from whence it appears, that Judas, to this time, had behaved outwardly as well as any of the other disciples; he had given no occasion, by his conduct, to suspect him more than any other: upon this broad intimation, or rather strong protestation which Christ made, that one of them should betray him, their eyes were not turned to him directly and particularly, but to one another.

the disciples looked one on another, doubting of whom he spake--Further intensely interesting particulars are given in the other Gospels: (1) "They were exceeding sorrowful" (Matthew 26:22). (2) "They began to inquire among themselves which of them it was that should do this thing" (Luke 22:23). (3) "They began to say unto Him one by one, Is it I, and another, Is it I?" (Mark 14:19). Generous, simple hearts! They abhorred the thought, but, instead of putting it on others, each was only anxious to purge himself and know if he could be the wretch. Their putting it at once to Jesus Himself, as knowing doubtless who was to do it, was the best, as it certainly was the most spontaneous and artless evidence of their innocence. (4) Jesus, apparently while this questioning was going on, added, "The Son of man goeth as it is written of Him, but woe unto that man by whom the Son of man is betrayed! It had been good for that man if he had not been born" (Matthew 26:24). (5) "Judas," last of all, "answered and said, Lord, is it I?" evidently feeling that when all were saying this, if he held his peace, that of itself would draw suspicion upon him. To prevent this the question is wrung out of him, but perhaps, amidst the stir and excitement at the table, in a half-suppressed tone as we are inclined to think the answer also was--"Thou hast said" (Matthew 26:25), or possibly by little more than a sign; for from John 13:28 it is evident that till the moment when he went out, he was not openly discovered.
