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?

John Gill on 2 Samuel 12:6
And he shall restore the lamb fourfold,.... Which was according to the law in Exodus 22:1; but Kimchi thinks, because the word is of the dual number, it signifies double the number, and that the sentence was to restore eight lambs, because he being a rich man stole from the poor man; so Mr. Weemse (s) renders it, twice four, twice as much as was commanded in the law; for the Hebrews, he observes, double in the dual number till they come to seven:
because he did this thing; committed this theft:
and because he had no pity; on the poor man, but took his all. The Jews observe, that accordingly David was punished with the loss of four of his children, that which was born of Bathsheba, Ammon, T…
