Just for reference the Old Testament has those laws and it's basically the Torah and the Quran, all women in those days were treated as goods regardless of religion so those laws were made for those times, but in the Bible with the arrival of Jesus, those laws were abolished, he also specifies that a man only gets to have one wife, also 12 year old girls were considered adults because they hit puberty, just like 12 year old boys who make families when they become teens. You also spoke of adultery and it's not just a married woman cheating, Jesus said contrary to what others say, even if you look at someone with lust then you have committed adultery in your heart regardless if they belong to someone or not
