18 I speak not of you all. I know those whom I have chosen; but that the scripture might be fulfilled, He that eats bread with me has lifted up his heel against me. 19 I tell you [it] now before it happens, that when it happens, ye may believe that I am [he]. 20 Verily, verily, I say to you, He who receives whomsoever I shall send receives me; and he that receives me receives him who has sent me.
21 Having said these things, Jesus was troubled in spirit, and testified and said, Verily, verily, I say to you, that one of you shall deliver me up. 22 The disciples therefore looked one on another, doubting of whom he spoke. 23 Now there was at table one of his disciples in the bosom of Jesus, whom Jesus loved. 24 Simon Peter makes a sign therefore to him to ask who it might be of whom he spoke. 25 But he, leaning on the breast of Jesus, says to him, Lord, who is it? 26 Jesus answers, He it is to whom I, after I have dipped the morsel, give it. And having dipped the morsel, he gives it to Judas [son] of Simon, Iscariote. 27 And, after the morsel, then entered Satan into him. Jesus therefore says to him, What thou doest, do quickly. 28 But none of those at table knew why he said this to him; 29 for some supposed, because Judas had the bag, that Jesus was saying to him, Buy the things of which we have need for the feast; or that he should give something to the poor. 30 Having therefore received the morsel, he went out immediately; and it was night.

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.
