20 He did the same with the cup after supper, saying, "This cup is the new covenant written in my blood, blood poured out for you.
21 "Do you realize that the hand of the one who is betraying me is at this moment on this table? 22 It's true that the Son of Man is going down a path already marked out - no surprises there. But for the one who turns him in, turns traitor to the Son of Man, this is doomsday." 23 They immediately became suspicious of each other and began quizzing one another, wondering who might be about to do this.

Commentary on Luke 22:19-20
(Read Luke 22:19-20)
The Lord's supper is a sign or memorial of Christ already come, who by dying delivered us; his death is in special manner set before us in that ordinance, by which we are reminded of it. The breaking of Christ's body as a sacrifice for us, is therein brought to our remembrance by the breaking of bread. Nothing can be more nourishing and satisfying to the soul, than the doctrine of Christ's making atonement for sin, and the assurance of an interest in that atonement. Therefore we do this in rememberance of what He did for us, when he died for us; and for a memorial of what we do, in joining ourselves to him in an everlasting covenant. The shedding of Christ's blood, by which the atonement was made, is represented by the wine in the cup.
Commentary on Luke 22:21-38
(Read Luke 22:21-38)
How unbecoming is the worldly ambition of being the greatest, to the character of a follower of Jesus, who took upon him the form of a servant, and humbled himself to the death of the cross! In the way to eternal happiness, we must expect to be assaulted and sifted by Satan. If he cannot destroy, he will try to disgrace or distress us. Nothing more certainly forebodes a fall, in a professed follower of Christ, than self-confidence, with disregard to warnings, and contempt of danger. Unless we watch and pray always, we may be drawn in the course of the day into those sins which we were in the morning most resolved against. If believers were left to themselves, they would fall; but they are kept by the power of God, and the prayer of Christ. Our Lord gave notice of a very great change of circumstances now approaching. The disciples must not expect that their friends would be kind to them as they had been. Therefore, he that has a purse, let him take it, for he may need it. They must now expect that their enemies would be more fierce than they had been, and they would need weapons. At the time the apostles understood Christ to mean real weapons, but he spake only of the weapons of the spiritual warfare. The sword of the Spirit is the sword with which the disciples of Christ must furnish themselves.
