(29) Because Judas had the bag.--Comp. Notes on John 12:6.

Buy those things that we have need of against the feast.--Here, again, it will be better to postpone the consideration of details in the order of the events of this week, and to deal with the question as a whole. (Comp. Excursus F: The Day of the Crucifixion of our Lord.)

That he should give something to the poor.--Such gifts seem to have been made at all festivals. Their thought was probably of gifts to enable the poor to obtain the lamb and other requisites for keeping the Passover.

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.For some of them thought,.... This was the thought of some of the disciples, it may be of all of them but John;

because Judas had the bag: which was for the common supply of Christ and his disciples, and for the relief of the poor; See Gill on John 12:6.

That Jesus had said unto him, buy those things that we have need of against the feast; the feast of the passover, which was to be two days after; and shows, that this was not the passover which Christ now ate with his disciples:

or that he should give something to the poor; for whom Christ cared, and had a hearty concern, and for whom Judas had very little, notwithstanding his high pretensions.
