I am truly sorry to be one to inform you that you must be more discerning in your reading and understanding of Scripture and especially before you write some conclusion for practically the entire world to read...all of which you have the potential to lead astray, but it is true.
I referred to the Laws of Justice regarding the death of the unborn and the order, by God, that in such cases the instigator or perpetrator should be put to death. These OT Laws, as you should well know, were set in place to govern mankind, specifically, the Jewish nation of Israel. Within this same set of Laws is the one you cite and the one I cited involving King David is within the Prophets and at that time the people were governed by the OT Law. God is much higher than us and judges as He finds most righteous for He is a righteous Judge.
I would expect these types of arguments and statements to come from some level of unbeliever, but not a Christian. They are a twisting of the facts of Scripture...finely so...in order to further your own pet belief or theory. Surely a straight forward reading of the Bible would not call for these pronouncements.
I did not indicate that anything other than mankind was the body governed; certainly not God.
