You may not approve of Polygamy but certainly God did, it was a part of Jewish law. If a man died leaving a widow and he had a brother the brother was to take his widow unto him as wife and raise up the dead mans children and even give the widow more children to raise up unto the dead man so that the dead brother would have descendants.
This actually was a wonderful law. The widow did not become destitute as a widow would if her husband had no brothers and children grew up in homes with a man at the head. The young men growing up could see what a man was supposed to be.
Today in our society and in many throughout the world we hand off that responsibility for our brothers family to the state. We pay the state to absolve us of that responsibility but then the children grow up fatherless and then don’t know what it means to be a father, it does great harm to societies. The Jewish law was better.
Monogamy is pretty much a Christian thing. While the New Testament does not say much about it, there is a proscription that a bishop be the husband of one wife. There are even arguments about that. Some say that means that you must be married to be wise enough to be a bishop other say it means you can not have more than one wife. How in the world that Catholicism gets celibacy out of that is beyond me.
I have one wife. One wife is a great thing. My wife is a wonderful woman, a wonderful wife, a wonderful friend and a wonderful person all around but, I don’t think I could do two of her or more. I have heard stories of polygamy being a good thing for all the participants but I just can’t fathom it. I have a special closeness with my wife that I can’t envision working with three or more. I would think that polygamy would be a great burden for a man. I am reminded how difficult life was for Isaac, Leah and Rachel. Issac loved Rachel more than Leah. That had to be a difficult situation for all involved.
