I’ve broached this subject before, repeatedly.
I just wanted to point out some things —

1. Adam and Eve being a monogamous relationship is NOT indicating The Most High’s favor TOWARD monogamous relationships. It is only an example of a man and woman being together. THAT IS ALL. That is reflected in all marital relationships in the Bible. There are NO same-sex marriages in the Bible. There are NO inter-species marriages in the Bible. You know why? Because these acts are FORBIDDEN/PROHIBITED by the Bible.
2. Arguments and negative situations in a polygynous relationship in the Bible is NOT indicative of The Most High being against polygyny! Monogamous relationships currently have a divorce rate of AROUND 50% in the United States, at least. NO marital relationship is going to be perfect! Whether it’s polygyny or monogamy, it’s the PEOPLE that will make or break it, not the relationship dynamic itself!
3. Verses concerning adultery and divorce have NOTHING TO DO with polygyny (UNLESS someone polygynous has committed adultery or gotten a divorce!) Adultery is the act of a man having sex with a married woman (NOT married to HIM). Divorce is the act of putting a wife away, or chosing NOT to be married to her anymore…
4. Men in the Bible taking foreign wives and being punished for it is NOT indicative of The Most High being against polygyny! The Most High SPECIFICALLY STATED that Hebrew men were NOT to take foreign women, and HE CALLED IT — he said they’d be led to worship other gods and HE WAS RIGHT AND IT HAPPENED EVERY TIME. That would have happened if the man and woman were MONOGAMOUS or POLYGYNOUS — the relationship dynamic had no bearing on their punishment!
5. Just because YOU feel it’s wrong DOESNT MEAN THAT ITS WRONG! People feel slavery was wrong — but slaves and slave masters were all in the Bible. Slavery is an economic system and NOT ONLY did it build the very country we live in (America… *ahem*), but IT IS STILL GOING ON TODAY.
Your FEELINGS have ABSOLUTELY NO BEARING on The Word of The Most High! Have you EVER analyzed why you feel the way you do about it? COULD IT BE BECAUSE YOU LIVE IN A COUNTRY BASED ON ROMAN PRINCIPLES — WHERE POLYGYNY IS WRONG, BUT SERIAL MONOGAMY AND AFFAIRS(and homosexual sex) WAS THE NAME OF THE DAY?? So because SOCIETY thinks it’s WRONG and it was BRED INTO YOU that it’s wrong, don’t you think that might have SOMETHING to do with why you feel that way?
Face it — the Bible doesn’t AGREE with you. In FACT, The Most High gave rules FOR polygyny.

When you are against polygyny I understand how hard it can be to change that. Our society feeds us monogamy as the ideal form of marriage — but it ALSO feeds us ALOT of other stuff that is completely backward and ridiculous.
The Bible NEVER speaks against polygyny, but it’s obvious that it happened then, and it happened now, and NEVER does The Most High pit himself against any of the men that practiced it for that reason.

STOP ADDING TO THE WORD OF THE MOST HIGH!

Deuteronomy 4:2 HNV

You shall not add

to the word which I command you, neither shall you diminish from it, that you may keep the mitzvot of the YHWH your Elohim, which I command you.

Deuteronomy 12:32 HNV
Whatever thing I command you, that shall you observe to do:

you shall not add thereto,

nor diminish from it.

Revelations 22:18 HNV
I testify to every man who hears the words of the prophecy of this book,

if anyone adds to them, may YHWH add to him the plagues which are written in this book.
