Well, except that Jesus literally told you not to defend yourself from takers. You can't get more direct than this: > But I say to you, Do not resist the one who is evil. But if anyone slaps you on the right cheek, turn to him the other also. And if anyone would sue you and take your tunic, let him have your cloak as well. And if anyone forces you to go one mile, go with him two miles. So, assuming Jesus was speaking literally, the only possible interpretation I can think of is that Jesus wanted you to buy a sword, but not use it against others. Why he wanted you to buy a sword, I don't know. Maybe he had a friend blacksmith.
