To get past that dead-horse, let me point out that NOWHERE IN THE BIBLE does it say that.
Oh?
Genesis 2
18 The Lord God said, “It is not good for the man to be alone. I will make a helper suitable for him.” (not 4 or 5)
19 Now the Lord God had formed out of the ground all the wild animals and all the birds in the sky. He brought them to the man to see what he would name them; and whatever the man called each living creature, that was its name. 20 So the man gave names to all the livestock, the birds in the sky and all the wild animals.
But for Adam no suitable helper was found. 21 So the Lord God caused the man to fall into a deep sleep; and while he was sleeping, he took one of the man’s ribs and then closed up the place with flesh. 22 Then the Lord God made a woman from the rib he had taken out of the man, and he brought her to the man. (singular) (Not a half rack)
23 The man said,
“This is now bone of my bones
and flesh of my flesh;
she shall be called ‘woman,’
for she was taken out of man.”
24 That is why a man leaves his father and mother and is united to his wife, and they become one flesh.
25 Adam and his wife were both naked, and they felt no shame. (Not wives)
Whinney!
“Many will point out that Adam had only Eve. That was God’s choice in THAT case. I’m a fairly bright man but I won’t try to extrapolate from such scant data that God meant all humans had to pair off in similar unions.”
“Whinney?” You have something backwards, I believe that sound comes from the other end of the horse.
A number of God’s prophets maintained more than one wife. In fact, it was common - in cases where a husband died - his wife became the wife of his brother. Remember, there was no State Welfare systems then and the new widow would have had no one to provide for her and her children.
You need to read more than just those parts you agree with.
