Cyril of Alexandria — as excerpted in the Catena Aurea on Luke 22:35-38

“Or else; When our Lord says, He who hath a purse, let him take it, likewise a scrip, His discourse He addressed to His disciples, but in reality He regards every individual Jew; as if He says, If any Jew is rich in resources, let him collect them together and fly. But if any one oppressed with extreme poverty applies himself to religion, let him also sell his cloak and buy a sword. For the terrible attack of battle shall overtake them, so that nothing shall suffice to resist it. He next lays open the cause of these evils, namely, that He suffered the penalty due to the wicked, being crucified with thieves. And when it shall have come at last to this, the word of dispensation will receive its end. But to the persecutors shall happen all that has been foretold by the Prophets. These things then God prophesied concerning what should befall the country of the Jews, but the disciples understood not the depth of His words, thinking they had need of swords against the coming attack of the traitor. Whence it follows; But they said, Lord, behold, here are two swords.”
