21 When Jesus had said this , He became troubled in spirit , and testified and said , "Truly , truly , I say to you, that one of you will betray Me." 22 The disciples began looking at one another , at a loss to know of which one He was speaking . 23 There was reclining on Jesus' bosom one of His disciples , whom Jesus loved . 24 So Simon Peter gestured to him, and said to him, "Tell us who it is of whom He is speaking ." 25 He, leaning back thus on Jesus' bosom , said to Him, "Lord , who is it?" 26 Jesus then answered , "That is the one for whom I shall dip the morsel and give it to him." So when He had dipped the morsel , He took and gave it to Judas , the son of Simon Iscariot . 27 After the morsel , Satan then entered into him. Therefore Jesus said to him, "What you do , do quickly ." 28 Now no one of those reclining at the table knew for what purpose He had said this to him. 29 For some were supposing , because Judas had the money box , that Jesus was saying to him, "Buy the things we have need of for the feast "; or else , that he should give something to the poor . 30 So after receiving the morsel he went out immediately ; and it was night .
31 Therefore when he had gone out, Jesus said , "Now is the Son of Man glorified , and God is glorified in Him; 32 if God is glorified in Him, God will also glorify Him in Himself , and will glorify Him immediately . 33 " Little children , I am with you a little while longer . You will seek Me; and as I said to the Jews , now I also say to you, 'Where I am going , you cannot e come .' 34 "A new commandment I give to you, that you love one another , even as I have loved you, that you also love one another . 35 " By this all men will know that you are My disciples , if you have love for one another ."

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.
