Unless someone could convince a group of them that his rival was a Hebrew, in which he could enslave him. Just don't beat him so hard that he dies. Well, not right away at least. It's okay as long as he lives at least a couple of days after the beating.
Or was a Midianite; then he could not only chop him into pieces, but could do the same to his wife, kids, and pets! And steal all his stuff! And his land!
Oh, and don't worry about running out of labels. Here's a few more to tide you over: the Hittites, the Amorites, the Canaanites, the Perizzites, the Hivites, and the Jebusites. Good news for the Jabeshgileads though - at least for the young female virgins. While everyone else with that label gets slaughtered, they only have to put up with capture, rape and sex slavery. Sweet.
Yep, this bible as law stuff is a good deal - that is unless you are the one being labeled.
One other thing to watch out for is the kinda stiff misdemeanor penalties. For instance:
A stubborn and rebellious son? You get stoned to death.
Have doubts about whether the bible is true? Stoned to death.
Someone in your family start to doubt the bible? Stone them to death.
Be a female and not be a virgin on your wedding night? Stoned to death.
Commit a homosexual act? Be put to death.
Commit adultery? Put to death.
Sleep with your mother-in-law? Both get burned to death.
Simply mention that maybe this stuff might be a little harsh? Stoned to death.
Not all the penalties are that bad, though:
Rape an unmarried virgin? Pay a 50 shekel fine and you get to keep her.
You can live in this hellish mythical country. I want no part of it.
While rereading my post, I started to recall that I'd heard of some distant land that ran on a very similar ruleset already. If only I could think of it I could recommend it to you so you could go live in your 'Utopia'.
Oh well. If I think of it I'll let you know. Sorry.
And the writer of this statement is who?
