27 Who is more important, the one who sits at the table or the one who serves? The one who sits at the table, of course. But not here! For I am among you as one who serves. 28 "You have stayed with me in my time of trial. 29 And just as my Father has granted me a Kingdom, I now grant you the right 30 to eat and drink at my table in my Kingdom. And you will sit on thrones, judging the twelve tribes of Israel.
31 "Simon, Simon, Satan has asked to sift each of you like wheat. 32 But I have pleaded in prayer for you, Simon, that your faith should not fail. So when you have repented and turned to me again, strengthen your brothers." 33 Peter said, "Lord, I am ready to go to prison with you, and even to die with you." 34 But Jesus said, "Peter, let me tell you something. Before the rooster crows tomorrow morning, you will deny three times that you even know me."
35 Then Jesus asked them, "When I sent you out to preach the Good News and you did not have money, a traveler's bag, or an extra pair of sandals, did you need anything?" "No," they replied. 36 "But now," he said, "take your money and a traveler's bag. And if you don't have a sword, sell your cloak and buy one! 37 For the time has come for this prophecy about me to be fulfilled: 'He was counted among the rebels.' Yes, everything written about me by the prophets will come true." 38 "Look, Lord," they replied, "we have two swords among us." "That's enough," he said.

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.
