[quote=Ziggy]"… Judas, one of the Twelve, arrived, accompanied by a large crowd, with swords and clubs, who had come from the chief priests and the elders of the people… And behold, one of those who accompanied Jesus put his hand to his sword, drew it, and struck the high priest’s servant, cutting off his ear. The Jesus said to him, “Put your sword back into its sheath, for all who take the sword will perish by the sword.”
Earlier on his way to give him self up at Carthage jail, Joseph told those around him that he goes like a lamb to the slaughter (he knew he was going to die), but feels confident in his worthiness before the Lord in all his actions.
At Carthage jail he was not submitting his life as a testimony to a lawful authority, but to a mob, and as such had the right to protect those that were with him. His actions saved the live of one.
And he said unto them, When I sent you without purse, and scrip, and shoes, lacked ye any thing? And they said, Nothing.
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.*
Sounds like the Lord thought it was ok to protect themselves in certain situations.
