27 For which is greater, he that sitteth at meat, or he that serveth? is not he that sitteth at meat? but I am in the midst of you as he that serveth. 28 But ye are they that have continued with me in my temptations; 29 and I appoint unto you a kingdom, even as my Father appointed unto me, 30 that ye may eat and drink at my table in my kingdom; and ye shall sit on thrones judging the twelve tribes of Israel.
31 Simon, Simon, behold, Satan asked to have you, that he might sift you as wheat: 32 but I made supplication for thee, that thy faith fail not; and do thou, when once thou hast turned again, establish thy brethren. 33 And he said unto him, Lord, with thee I am ready to go both to prison and to death. 34 And he said, I tell thee, Peter, the cock shall not crow this day, until thou shalt thrice deny that thou knowest me.
35 And he said unto them, When I sent you forth without purse, and wallet, and shoes, lacked ye anything? And they said, Nothing. 36 And he said unto them, But now, he that hath a purse, let him take it, and likewise a wallet; and he that hath none, let him sell his cloak, and buy a sword. 37 For I say unto you, that this which is written must be fulfilled in me, And he was reckoned with transgressors: for that which concerneth me hath fulfilment. 38 And they said, Lord, behold, here are two swords. And he said unto them, It is enough.
Matthew Henry's Commentary on Luke 22:27-38
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.
