If you want to say that god made concessions to man go ahead. He still instructed them in how to hold chattel slaves and implied that they could do so ruthlessly, only restricting them from doing so to eachother.
Leviticus 25:44-46
44 “‘Your male and female slaves are to come from the nations around you; from them you may buy slaves. 45 You may also buy some of the temporary residents living among you and members of their clans born in your country, and they will become your property. 46 You can bequeath them to your children as inherited property and can make them slaves for life, but you must not rule over your fellow Israelites ruthlessly.
In Denmark where I’m from we’ve just held mayoral elections and an interesting thing happened that highlights how much voting systems matter. In one particular municipality a party got enough votes that they had more seats in the local legislature than to hey had candidates. This meant that they appointed someone from a different party to the final seat. They got more votes than they could represent themselves so they chose who they thought most aligned with them and appointed that person. No votes were ignored due to happenstance, there were clear rules to handle it.
Now I very much do not agree with this party and I’m saddened by their popularity in the area, but such is life in a democracy.
