2 Samuel 12:9

To be thy wife — To marry her whom he had defiled, and whose husband he had slain, was an affront upon the ordinance of marriage, making that not only to palliate, but in a manner to consecrate such villainies. In all this he despised the word of the Lord; (so it is in the Hebrew.) Not only his commandment in general, but the particular word of promise, which God had before sent him by Nathan, that he would build him an house: which sacred promise if he had had a due value for, he would not have polluted his house with lust and blood.
