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 12:5
And David's anger was greatly kindled against the man,.... That had done this, taking it for a real fact:
and he said to Nathan, as the Lord liveth, the man that hath done this thing shall surely die; which be said in the transport of his wrath and fury; otherwise a thief, according to the law of Moses, was not to be put to death, but to make restitution; and if he was not able to make it, then to be sold, but he was not to die for it; but David thought the crime was so greatly aggravated by being done by a rich man, and by the loss the poor man sustained, it being his all, and the fact, in all its circumstances, so cruel and barbarous, that the guilty person ought to die: how much more veh…
