21 When Jesus had thus said, he was troubled in the spirit, and testified, and said, Verily, verily, I say unto you, that one of you shall betray me. 22 The disciples looked one on another, doubting of whom he spake. 23 There was at the table reclining in Jesus' bosom one of his disciples, whom Jesus loved. 24 Simon Peter therefore beckoneth to him, and saith unto him, Tell [us] who it is of whom he speaketh. 25 He leaning back, as he was, on Jesus' breast saith unto him, Lord, who is it? 26 Jesus therefore answereth, He it is, for whom I shall dip the sop, and give it him. So when he had dipped the sop, he taketh and giveth it to Judas, [the son] of Simon Iscariot. 27 And after the sop, then entered Satan into him. Jesus therefore saith unto him, What thou doest, do quickly. 28 Now no man at the table knew for what intent he spake this unto him. 29 For some thought, because Judas had the bag, that Jesus said unto him, Buy what things we have need of for the feast; or, that he should give something to the poor. 30 He then having received the sop went out straightway: and it was night.
31 When therefore he was gone out, Jesus saith, Now is the Son of man glorified, and God is glorified in him; 32 and God shall glorify him in himself, and straightway shall he glorify him. 33 Little children, yet a little while I am with you. Ye shall seek me: and as I said unto the Jews, Whither I go, ye cannot come; so now I say unto you. 34 A new commandment I give unto you, that ye love one another; even as I have loved you, that ye also love one another. 35 By this shall all men know that ye are my disciples, if ye have love one to another.
36 Simon Peter saith unto him, Lord, whither goest thou? Jesus answered, Whither I go, thou canst not follow now; but thou shalt follow afterwards. 37 Peter saith unto him, Lord, why cannot I follow thee even now? I will lay down my life for thee. 38 Jesus answereth, Wilt thou lay down thy life for me? Verily, verily, I say unto thee, The cock shall not crow, till thou hast denied me thrice.

Commentary on John 13:18-30
(Read John 13:18-30)
Our Lord had often spoken of his own sufferings and death, without such trouble of spirit as he now discovered when he spake of Judas. The sins of Christians are the grief of Christ. We are not to confine our attention to Judas. The prophecy of his treachery may apply to all who partake of God's mercies, and meet them with ingratitude. See the infidel, who only looks at the Scriptures with a desire to do away their authority and destroy their influence; the hypocrite, who professes to believe the Scriptures, but will not govern himself by them; and the apostate, who turns aside from Christ for a thing of naught. Thus mankind, supported by God's providence, after eating bread with Him, lift up the heel against Him! Judas went out as one weary of Jesus and his apostles. Those whose deeds are evil, love darkness rather than light.
Commentary on John 13:31-35
(Read John 13:31-35)
Christ had been glorified in many miracles he wrought, yet he speaks of his being glorified now in his sufferings, as if that were more than all his other glories in his humbled state. Satisfaction was thereby made for the wrong done to God by the sin of man. We cannot now follow our Lord to his heavenly happiness, but if we truly believe in him, we shall follow him hereafter; meanwhile we must wait his time, and do his work. Before Christ left the disciples, he would give them a new commandment. They were to love each other for Christ's sake, and according to his example, seeking what might benefit others, and promoting the cause of the gospel, as one body, animated by one soul. But this commandment still appears new to many professors. Men in general notice any of Christ's words rather than these. By this it appears, that if the followers of Christ do not show love one to another, they give cause to suspect their sincerity.
Commentary on John 13:36-38
(Read John 13:36-38)
What Christ had said concerning brotherly love, Peter overlooked, but spoke of that about which Christ kept them ignorant. It is common to be more eager to know about secret things, which belong to God only, than about things revealed, which belong to us and our children; to be more desirous to have our curiosity gratified, than our consciences directed; to know what is done in heaven, than what we may do to get thither. How soon discourse as to what is plain and edifying is dropped, while a doubtful dispute runs on into endless strife of words! We are apt to take it amiss to be told we cannot do this and the other, whereas, without Christ we can do nothing. Christ knows us better than we know ourselves, and has many ways of discovering those to themselves, whom he loves, and he will hide pride from them. May we endeavour to keep the unity of the Spirit in the bond of peace, to love one another with a pure heart fervently, and to walk humbly with our God.
