Matthew Poole and continuators on 2 Samuel 12:14

14 Howbeit, because by this deed thou hast given great occasion to the enemies of the LORD to blaspheme , the child also that is born unto thee, shall surely die .

i. e. To reproach both God and his People, and the true Religion. For though these were not concerned in David's Sin, the blame and shame of which should have been appropriated to him; yet Heathens and wicked men would, according to their own evil Minds, and malicious Hearts, fasten the Reproach of this upon God and Religion; as if God were unholy, because the man after God's own heart was so; and partial, in conniving at so great a Crime, when Saul was cast off for a far less Sin: and negligent in the Government of the World, and of his Church in suffering such a Wickedness, as even Heathens have abhorred to go unpunished; and as if all Religion were but Hypocrifie and Imposture, and a pretence for Villanies. Besides, the Ammonites upon their success against Uriah and his Party, did doubtless magnifie and praise their Idols, and blaspheme the God of Israel.

Which, considering his Affection to it, and the Punishment threatned to the poor innocent Infant for his sake, must needs be grievous to him.
