The Two Swords

Luke chapter 22 and verse 36. It says, then said he unto them, but now he that have the purse. Let him sell his garment and buy one. Why is this saying run around in a loin cloth if you have to, because you're going to need weapons in the future? Doesn't sound like him. Same caller brings up that there's a follow up verse two verses later. So he has an interesting assessment of what that means.
