31 Simon, Simon, Satan has made a request to have you, so that he may put you to the test as grain is tested: 32 But I have made prayer for you, that your faith may not go from you: and when you are turned again, make your brothers strong. 33 And he said to him, Lord, I am ready to go with you to prison and to death. 34 And he said, I say to you, Peter, before the cock's second cry today, you will say three times that you have no knowledge of me.
35 And he said to them, When I sent you out without money or bag or shoes, were you in need of anything? And they said, Nothing. 36 And he said to them, But now, he who has a money-bag, or a bag for food, let him take it: and he who has not, let him give his coat for money and get a sword. 37 For I say to you that these words will be put into effect in me, And he was numbered among the evil-doers: for what has been said in the Writings about me has an end. 38 And they said, Lord, here are two swords. And he said, 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.
