From time to time I mention Jesus Last Supper injunction to His followers to “take your purse, and the money in your traveling bag, and buy a sword.”
That order is both precise – and delightfully imprecise. Greek is as well provided with words for one sort or another of edged weapons as English, and one fairlly comprehensive “dictionary of swords” fills two fat volumes.
I am told that the word Jesus used denotes an edged weapon somewhat shorter and lighter than the Centurian’s gladius, sixteen to eighteen inches in overall length, sharp oint, two edges, with a pronounced blood groove and a one handed grip.
A “small sword,” in reality. In a world where five feet was a normal height at maturity, that was plenty to fend off a robber, or even let some daylight into the black heart of a despot, without becoming a burden.
Swords are out of fashion, largely because they take almost daily practice to keep one’s skills at a high level. Guns a much more satisfactory solution to the need for a weapon to defend self and others. Besides, the mortality rte from gunshot wounds is lower than that from knife attacks.
Given that, substituting a handgun for a sword should be an approved substitution. And almost any suitable handgun will do.
