27 "Who would you rather be: the one who eats the dinner or the one who serves the dinner? You'd rather eat and be served, right? But I've taken my place among you as the one who serves. 28 And you've stuck with me through thick and thin. 29 Now I confer on you the royal authority my Father conferred on me 30 so you can eat and drink at my table in my kingdom and be strengthened as you take up responsibilities among the congregations of God's people.
31 "Simon, stay on your toes. Satan has tried his best to separate all of you from me, like chaff from wheat. 32 Simon, I've prayed for you in particular that you not give in or give out. When you have come through the time of testing, turn to your companions and give them a fresh start." 33 Peter said, "Master, I'm ready for anything with you. I'd go to jail for you. I'd die for you!" 34 Jesus said, "I'm sorry to have to tell you this, Peter, but before the rooster crows you will have three times denied that you know me."
35 Then Jesus said, "When I sent you out and told you to travel light, to take only the bare necessities, did you get along all right?" "Certainly," they said, "we got along just fine." 36 He said, "This is different. Get ready for trouble. Look to what you'll need; there are difficult times ahead. Pawn your coat and get a sword. 37 What was written in Scripture, 'He was lumped in with the criminals,' gets its final meaning in me. Everything written about me is now coming to a conclusion." 38 They said, "Look, Master, two swords!" But he said, "Enough of that; no more sword talk!"

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.
