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.

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.
