Deuteronomy 21:15

Ver. 15. If a man have two wives— Moses here enacts, that where any Israelite had two wives, (for polygamy, contrary to the original institution of marriage, was suffered, but never enjoined) and when the man was partial in his affections towards them; such partiality should not hinder the right of eldership and inheritance in any of the children. If the son of the wife whom he least loved were his first, her male heir should inherit as his eldest son, according to ancient custom in that case. Genesis 25:31. Grotius has remarked, that this law is extremely wise, to prevent any intrigues from the ascendancy of the second and favourite wife for the advantage of her children. A similar law existed among the Lombards; but it is to be observed, that the more necessary this law was, the more palpably does it demonstrate the inconveniencies of polygamy.
