2 Samuel 5:13 - Clarke's commentary and critical notes on the Bible

And David took him more concubines and wives out of Jerusalem, after he was come from Hebron: and there were yet sons and daughters born to David. David took him more concubines - He had, in all conscience, enough before; he had, in the whole, eight wives and ten concubines. That dispensation permitted polygamy, but from the beginning it was not so; and as upon an average there are about fourteen males born to thirteen females, polygamy is unnatural, and could never have entered into the original design of God.
