27 For who is greater, the one who is at the table or the one who serves? Is it not the one at the table? But I am among you as one who serves. 28 "You are those who have stood by me in my trials; 29 and I confer on you, just as my Father has conferred on me, a kingdom, 30 so that you may eat and drink at my table in my kingdom, and you will sit on thrones judging the twelve tribes of Israel.
31 "Simon, Simon, listen! Satan has demanded to sift all of you like wheat, 32 but I have prayed for you that your own faith may not fail; and you, when once you have turned back, strengthen your brothers." 33 And he said to him, "Lord, I am ready to go with you to prison and to death!" 34 Jesus said, "I tell you, Peter, the cock will not crow this day, until you have denied three times that you know me."
35 He said to them, "When I sent you out without a purse, bag, or sandals, did you lack anything?" They said, "No, not a thing." 36 He said to them, "But now, the one who has a purse must take it, and likewise a bag. And the one who has no sword must sell his cloak and buy one. 37 For I tell you, this scripture must be fulfilled in me, "And he was counted among the lawless'; and indeed what is written about me is being fulfilled." 38 They said, "Lord, look, here are two swords." He replied, "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.
