Caesar also condoned adultery which was legal in Rome, but Jesus spoke out against that. So, yes, He did speak against Roman law, He just overlooked slavery when He chose which things were worth mentioning.
No, actually, we've evolved to be social creatures. Over time, we've learned to look at the big picture, and plan for the future, and so we've developed more complicated morals than constantly seeking instant gratification. For instance, humans are empathetic creatures, in general. We feel happy when other humans feel happy. So making others feel happy is good because it makes us happy. That's how we're wired, biologically speaking. And since there are objectively better methods to make other people happy, I absolutely can have objective morality without a need to invoke a creator. We've studied anger and hatred, and we've studied compassion and kindness, and we know what makes humans happy and what doesn't.
But let's get back to the OT slavery that I've glossed over thus far.
Because there aren't any listed in the OT. Should we just imagine there are laws that the OT doesn't state? But let's ignore that for a moment. We have a law that says don't kidnap, if someone get's caught buying a kidnapped person, then they're just as guilty as the kidnapper. Fine. You can't say that the entire slave trade was outlawed by this verse because one type of slave wasn't allowed. Imagine foreigners who had POWs as slaves. Those people aren't kidnapped, so they should be free to be traded. There's no reason to think they weren't.
There's obviously a distinction, and I don't need to know what it is specifically. Clearly, Israelites and foreigners operated under different rules and had different protections via the Law. So you can't take a law and claim it protected foreigners too. Think about the law that says Hebrew men can't be slaves for life unless they volunteer. Making that specific distinction sure seems to point to the fact that foreigners could be made slaves for life.
You asked how in the world Moses could make laws that enslaved people as if there was no possible reasoning for it. I'm not saying that was necessarily Moses' reasoning, but it is entirely plausible that he only saw Israelites as being above out and out slavery. He saw them as God's chosen people, why wouldn't they be deserving of better treatment than everyone else?
Nope. The cities I mentioned are outside of the land promised to the Israelites, so not only are they not the Canaanites that God commanded to exterminate every last one, they are not inside the promised land at all. There were two outcomes when Israel came upon one of these cities. Forced labor and killing every last male of a certain age. If your choice is labor or death, that's slavery. It's possible that they mean tributaries, it's also entirely possible that they mean POWs. If they end up killing all the men, then they take the women as "plunder" and "spoils of war", so I see no reason to speculate that they left even the men where they were instead of taking them back to Israel.
All peace means is "not war". You can't speculate that they were being diplomatic just because they talked about the non-war option of forced labor. No matter what, it was labor or death. No in between.
Yes but Adultery wasn't an economic foundation of his country nor was it a law. Christians were killed just for being a Christian, sometimes even being blamed because the former gods were not working. I do not think we can logically expect Jesus to go about renouncing every Roman law that is immoral, essentially waging war against Rome, and live long enough to be killed by the Jews. That would be an outrageous and unrealistic expectation.
There are a lot of social creatures out there that do not have our morals. Ants, Bees, wolves, Lions, birds. When I was in college I watched ducks get rapped nearly everyday day outside the lunch hall window. They evolved the morality that that was okay, and there is no binding force that keeps our morality what it is if we ground it to evolution, nor is it any highground. Evolution is concerned only with survival that passes on DNA. That is the extent of it. Turn the other cheek, and don't enslave man, doesn't help me pass on my DNA. And don't forget happiness itself, as a biological function, can evolve, there is nothing holding it to what it is besides mutation and natural selection. While this may seem insurmountable now all it takes is a selective pressure and all this "moral highground" goes out the window, those that are immoral survive on the backs of their brethren and pass on their genes, now epigenetically selected, and survival selected toward immorality. This morality is a house build on sand. And think back to the ANE under this condition, they
were acting upon their evolved morality at that time, while we, in the modern era, are merely acting according to a different evolved morality which may change entirely in a thousand years. There is no high ground, no truly right or wrong behavior, or even compulsion to obey our selected morality under this system. So if you do feel like what they did
is objectively wrong you should reject your current grounding as it's foundation is not capable of supporting such a weight. Israel is merely unfashionable here, not truly wrong. We cannot judge an inch without a ruler, and the ruler being applied here persistently changes it's length making it no good at all.
The OT is not an exhaustive law, it is a collection of Law. Your expectations on how to consider this text are mistaken, that is not just my thoughts, but comes from a lecture at Yale University on Biblical law. Yes we should consider that there are other laws, do you think a nation could survive on a few pages from these two books? This is that prejudice and bias again. You try and find whatever loophole you can to try to make Israel a monster. But that is just a hopeful argument from silence. But I'd like to know why you want there to be something wrong here? Why is that? What led you to leave Christianity, and can you honestly say you bear no resentment or anger toward it?
Foreigners can be slaves for life... if that is what they choose. It just doesn't work to try to search for loopholes to make Israel the bad guy because it will always stand on silence. Leviticus 19:18
but love your neighbor as yourself. Leviticus 19:13
You shall treat the stranger who sojourns with you as the native among you, and you shall love him as yourself. God didn't want Israelites to be slaves forever because they serve God as their master, and they were slaves in Egypt. That is why they are different.
Ok if Moses thought Israelites were better then why did he not adopt a law like Hammurabi where the law was relative to ones social situation rather than the law of equality which Moses actually created? Rich or poor, native or foreigner, the law is the same for each (Quantitative values varied in accordance with the poor).
You are going to have to tell me what city you are referring too, as the text in reference is a general proposition not referring to a specific city but vague references of distance, and I don't recall you ever mentioning a specific city. I know there were cities on the way, some let Israel pass some did not but I beleive this takes place after that. As far as the cities that resisted the men were killed. All that is left are orphans and their mothers, which is exactly what Israel takes in. It would be worse to leave them there to die of starvation. Neither of us knows how they are treated because such laws are not included, but we do know they are destitute if they remain.
I think it was a tributary as the older LLX renders more clearly, and "forced" is not in the text. God gave the land to Israel, to be a nation of priests for the sake of all nations. There were not going to be any cities that did their own thing, worshiped their own gods, and polluted the land. This was Gods allotment in all the earth, for the sake of all the earth. If they wished to remain they would serve the Lord and I see nothing wrong with that.
