I understand that god never instructed people to keep slaves, but he also didn't seem to have a problem with it. My questions never indicate that.
It only seems
to you that God didn't have a problem with slavery, because of your bias. None of the texts you've quoted say anything about whether God had a problem with slavery. The texts only show what God told Israel about treating slaves, and the punishment for killing slaves.
I understand that god is saying if your going to keep slaves this is how they should be treated, You can beat them with a rod and not be punished as long as they don't die immediately, because they are your property.
Apparently you need to reread the verse you wanted to show us:
21 If, however, he [c]survives a day or two, no vengeance shall be taken; for he is his [d]property.
This verse says that no "life for life" punishment will be required if the slave doesn't die immediately. It doesn't say there's no punishment.
Now, my question is. Do you agree that these are good rules to give people about how to treat another person?
Again, God gave these rules to a specific nation at a specific time in history. Taking into consideration everything about the ANE, then yes.
In what possible context, situation, time period, social condition would the above rules on how to treat a person be acceptable to you?
Is there any time that you would be ok with keeping people as property and beating them?
In the ANE at the time shown in scripture.
If your father realised you were keeping your brother a slave and he put the rules in place that you could beat your brother as much as you want as long as you don't kill him, would you say these rules are good rules and are in place to protect your brother? What would you think of your father?
That's a horrible analogy, outlaw. But, I'll attempt to work with it, using the context of the ANE.
If my brother owed me money that he couldn't repay, then he'd offer himself as my slave to work off the debt. If my brother became lazy, and stopped working to pay off what he owed me, and the punishment that the law required was a physical beating, then that's the punishment.
And as usual, you misunderstand my father's rules. He never said I can beat him as much as I want.
