John Gill On Luke 22:21
with me on the table; and is an aggravation of his sin, that one that sat with him at his table, ate bread with him, and dipped his morsel in the same dish, should be the betrayer of him, according to the prophecy in
Psalm 41:9 as well as describes and points at the person that should do this action, even one of his disciples; for which disciples, he had just now said, his body is given, and his blood is shed. The phrase, "with me", is left out in the Syriac and Persic versions.
From Luke's account it appears most clearly, that Judas was not only at the passover, but at the Lord's supper, since this was said when both were over.
Matthew Henry On Luke 22:21
By placing this after the institution of the Lord's supper, though in Matthew and Mark it is placed before it,
it seems plain that Judas did receive the Lord's supper, did eat of that bread and drink of that cup for, after the solemnity was over, Christ said,
Behold, the hand of him that betrayeth me is with me on the table. There have been those that have eaten bread with Christ and yet have betrayed him.
Jesus Christ is Almighty God, and would have known that Judas was to leave the room shortly after the Lord's Supper was given by Him. If He did not intend for Judas to eat the bread, and drink the wine, representing His body and blood, then surely to be very clear, He would have instituted the Supper after Judas had left the room. The fact that Judas not only took this very important Supper with Jesus and the 11, and was told by Jesus, "And he took bread, and gave thanks, and brake
it, and gave unto them, saying, This is my body which is given for
you...Likewise also the cup after supper, saying, This cup
is the new testament in my blood, which is shed for
you.", no doubt meant that Jesus' death also included Judas along with the other 11. It is only because of ones "theology", that objection would be made to the plain reading of Scripture.
