От Иоанна 13:22

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" (Mat 26:22). (2) "They began to inquire among themselves which of them it was that should do this thing" (Luk 22:23). (3) "They began to say unto Him one by one, Is it I, and another, Is it I?" (Mar 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" (Mat 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" (Mat 26:25), or possibly by little more than a sign; for from Joh 13:28 it is evident that till the moment when he went out, he was not openly discovered.

Our Saviour having finished his public discourses, in which he "endured the contradiction of sinners," now applies himself to a private conversation with his friends, in which he designed the consolation of saints. Henceforward we have an account of what passed between him and his disciples, who were to be entrusted with the affairs of his household, when he was gone into a far country; the necessary instructions and comforts he furnished them with. His hour being at hand, he applies himself to set his house in order. In this chapter I. He washes his disciples' feet (v. 1-17). II. He foretels who should betray him (Joh 13:18-30). III. He instructs them in the great doctrine of his own death, and the great duty of brotherly love (Joh 13:31-35). IV. He foretels Peter's denying him (Joh 13:36-38).
