So how many wives is best? The answer is ONE, but it is a little more complicated than that. Polygamy is mentioned and acknowledged in the Bible, but it is never endorsed.
What about the women who are spared from the destruction of their cities in war? What about the children and their inheritance for those with two wives. It is complicated, but join me for 7 minutes while we don't ignore it.
