22:36 {m} Then said he unto them, But now, he that hath a purse, let him take [it], and likewise [his] scrip: and he that hath no sword, let him sell his garment, and buy one.
(m) He says all this using an allegory, as if he said, O my friends and fellow soldiers, you have lived until now in relative peace: but now there is at hand a most severe battle to be fought, and you must therefore lay all other things aside and think about dressing yourselves in armour. And what this armour is, is shown by his own example, when he prayed afterward in the garden and reproved Peter for striking with the sword.
22:36 But now. Now has come a time of trial when all will be against you.
He that hath no sword, let him... buy one. Not to be taken literally, but a striking way of saying that enemies upon every side will assail them.
22:36 But now - You will be quite in another situation. You will want every thing. He that hath no sword, let him sell his garment and buy one - It is plain, this is not to be taken literally. It only means, This will be a time of extreme danger.
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.
