I don't remember the actual laws mentioned in the Bible but it seems that the old fathers took multiple wives. Aaand we've seen how well that went for them with all the drama, ranging from stealing blessings to trading in narcotics. 
So I think that even if it's allowed, it would be mentally and economically preferable to stay monogamous and pull all the resources into rearing a single set of kids that wouldn't be backstabbing each other at the slightest provocation.
If only the rivalry wont destroy the marriage because the Bible definitely talks against divorce.
Women care about status in comparison to other women. That's why they bad-mouth men that broke up with them, they don't want any other women gaining access to resources/status that man provides. Putting 4 of them in the same house is recipe for drama.
Hard to resist that sweet, sweet alimony money that can be spent while going back to the dating pool.

Today we divorce our spouses right and left. The laws have changed enough that the lawyers make money out of the divorces.
