Matthew Henry on 2 Samuel 12:1-14
It seems to have been a great while after David had been guilty of adultery with Bath-sheba before he was brought to repentance for it. For, when Nathan was sent to him, the child was born (Sa2 12:14), so that it was about nine months that David lay under the guilt of that sin, and, for aught that appears, unrepented of. What shall we think of David's state all this while? Can we imagine that his heart never smote him for it, or that he never lamented it in secret before God? I would willingly hope that he did, and that Nathan was sent to him, immediately upon the birth of the child, when the thing by that means came to be publicly known and talked of, to draw from him an open confession of…

Sa2 12:1-4
Nathan's Reproof. - Sa2 12:1. To ensure the success of his mission, viz., to charge the king with his crimes, Nathan resorted to a parable by which he led on the king to pronounce sentence of death upon himself. The parable is a very simple one, and drawn from life. Two men were living in a certain city: the one was rich, and had many sheep and oxen; the other was poor, and possessed nothing at all but one small lamb which he had bought and nourished (יחיּה, lit. kept alive), so that it grew up in his house along with his son, and was treated most tenderly and loved like a daughter.
