So slavery being moral for some people and immoral for another, by definition, is not moral absolutism.
Beating a slave without knocking out a tooth, still harms your wellbeing. What makes you think that a tooth must be knocked out in order for it to harm your wellbeing? And since it's not immoral for you to beat a slave as long as you didn't knock the tooth out, violate your wellbeing. That makes it immoral.
Nice try.
I agree. Slavery as a general principle is not a moral absolute, however, one could follow biblical precepts for slavery (be both a slave owner and love your slave as yourself, for two examples) and actually use slavery for good, for restitution (remember that slavery in the OT is mostly an alternative to death following warfare).
Before you respond to the above, CONSIDER:
Yes, beating a slave is not loving one's neighbor, yes, so the Bible prescribes
more laws to punish violent
slavers than
any other class of person. Let's rephrase so you understand Bible laws as if you and I were Bible-era judges:
1) We have a fight today, I'm a born again Christian, you strike me in the face, you say, "Oh man! Sorry, BB!" I get up, shake it off, and say, "No prob, you didn't hit me that hard, just caught me off balance, I fell down, I'm fine, don't sweat it. It's over."
2) " " but you knock my tooth loose from my mouth. I say, "I forgive you, I'm a Christian, do you mind paying for the replacement filler tooth I'm getting at the dentist? You say, "Sure!" because you're a nice person.
3) " " You refuse to pay for my tooth and I forgive you, sincerely, yet pursue you in Small Claims for the dental bill since it's really your dental bill (Christians are allowed to sue non-Christians as a last resort, per the NT).
I think you see my point. Or I hope you see it!

You are free to think as you choose, but seem to think the Bible, rather than agreeing with 1-3 above, is saying, "YES! Go ahead and beat the living stuffing out of your slave, he's not a person. And if his tooth falls out, let him have a day off work or something."
What you're missing -- if that's how the Bible treats slaves, WHY PUT IN A LAW ABOUT THEIR TOOTH OR IF THEY DIE AT ALL? Why bother? Why not instead say, "No one cares if you beat a slave, his tooth comes loose, or he dies. He's not your responsibility."

Once you see their are protection/union/safety laws FOR slaves in the Bible, not AGAINST slaves, you'll see the difference between Theocratic Israel and the nations without direct teaching from God. And then you only have to answer "Were there any good reason(s) slavery was permissible in Bible times?" or "Why weren't the NT writer abolitionists?"
