Our Lord told the Apostles to buy a sword, which, apparently they already had 2 swords, Our Lord approved.....
Luke 22:34 And he said: I say to thee, Peter, the cock shall not crow this day, till thou thrice deniest that thou knowest me. And he said to them: [35] When I sent you without purse, and scrip, and shoes, did you want anything?
[36] But they said: Nothing. Then said he unto them: But now he that hath a purse, let him take it, and likewise a scrip; and he that hath not, let him sell his coat, and buy a sword. [37] For I say to you, that this that is written must yet be fulfilled in me: And with the wicked was he reckoned. For the things concerning me have an end. [38] But they said: Lord, behold here are two swords. And he said to them, It is enough... [50]And one of them struck the servant of the high priest, and cut off his right ear.
