27 For who is the greater, one who reclines at table or one who serves? Is it not the one who reclines at table? But I am among you as the one who serves. 28 "You are those who have stayed with me in my trials, 29 and I assign to you, as my Father assigned to me, a kingdom, 30 that you may eat and drink at my table in my kingdom and sit on thrones judging the twelve tribes of Israel.
31 "Simon, Simon, behold, Satan demanded to have you,[1] that he might sift you like wheat, 32 but I have prayed for you that your faith may not fail. And when you have turned again, strengthen your brothers." 33 Peter[2] said to him, "Lord, I am ready to go with you both to prison and to death." 34 Jesus[3] said, "I tell you, Peter, the rooster will not crow this day, until you deny three times that you know me."
35 And he said to them, "When I sent you out with no moneybag or knapsack or sandals, did you lack anything?" They said, "Nothing." 36 He said to them, "But now let the one who has a moneybag take it, and likewise a knapsack. And let the one who has no sword sell his cloak and buy one. 37 For I tell you that this Scripture must be fulfilled in me: 'And he was numbered with the transgressors.' For what is written about me has its fulfillment." 38 And they said, "Look, Lord, here are two swords." And he said to them, "It is enough."

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.
