Matthew 26:52

Shall perish by the sword. This was not to condemn the use of the sword, when employed on a just cause, or by lawful authority. Euthymius looks upon it as a prophecy that the Jews should perish by the sword of the Romans. (Witham) --- Our divine Saviour would not permit this apostle to continue in his pious zeal for the safety of his Master. He says to him: put up thy sword. For he could not be unwilling to die for the redemption of man, who chose to be born for that end alone. Now, therefore, he gives power to his implacable enemies to treat him in the most cruel manner, not willing that the triumph of the cross should be in the least deferred; the dominion of the devil and man's captivity in the least prolonged. (St. Leo)
