It is notable that every instance of polygamy in the Bible produces some ill effect. When Abraham took Hagar as a concubine and produced Ishmael, Ishmael became the father of Arab peoples, who have been the enemies of the Jewish people throughout history, even until this day. When Jacob took Leah, Rachel, and two others, the sons of the differnt wives quarrelled and had strife among themselves-- since Rachel was the favorite wife and received special treatment, he was sold by his brothers into Egypt, where of course the rest of the family followed and eventually were enslaved. David’s sons by different wives also faught amongst themselves, Absalom even waging war against his siblings and his father. The Old Testament, far from condoning polygamy, shows us the natural ill effects. Interestingly, the Mosaic law says that a king must not multiply gold, wives, and horses-- all of which Solomon did and ended his reign as a tyrant. It would appear that polygamy was a custom of the day, not condoned by God.
