18 I am not speaking of you all; I know whom I have chosen; it is that the scripture may be fulfilled, 'He who ate my bread has lifted his heel against me.' 19 I tell you this now, before it takes place, that when it does take place you may believe that I am he. 20 Truly, truly, I say to you, he who receives any one whom I send receives me; and he who receives me receives him who sent me."
21 When Jesus had thus spoken, he was troubled in spirit, and testified, "Truly, truly, I say to you, one of you will betray me." 22 The disciples looked at one another, uncertain of whom he spoke. 23 One of his disciples, whom Jesus loved, was lying close to the breast of Jesus; 24 so Simon Peter beckoned to him and said, "Tell us who it is of whom he speaks." 25 So lying thus, close to the breast of Jesus, he said to him, "Lord, who is it?" 26 Jesus answered, "It is he to whom I shall give this morsel when I have dipped it." So when he had dipped the morsel, he gave it to Judas, the son of Simon Iscariot. 27 Then after the morsel, Satan entered into him. Jesus said to him, "What you are going to do, do quickly." 28 Now no one at the table knew why he said this to him. 29 Some thought that, because Judas had the money box, Jesus was telling him, "Buy what we need for the feast"; or, that he should give something to the poor. 30 So, after receiving the morsel, he immediately went out; 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.
