Luke 22:36, American King James Version: Then said he to them, But now, he that has a purse, let him take it, and likewise his money: and he that has no sword, let him sell his garment, and buy one.
One of my favorite verses....except for this version from the Cotton Patch: Luke & the Happenings. (I'm not making this up, honest).
Luke 22:36 He said, "Okay, but now if you've got a wallet, go get it; and do the same if you have a suitcase. If you don't have either, sell your shirt and buy a switchblade.
