John 13:29

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.
