2 Samuel 12:9 Douay-Rheims

Why therefore hast thou despised the word of the Lord, to do evil in my sight? Thou hast killed Urias the Hethite with the sword, and hast taken his wife to be thy wife, and hast slain him with the sword of the children of Ammon.

“Therefore, Nathan went to David and wove a dramatic act for judgment. And what did he say? "My king, I want your judgment. There was a certain rich man and a certain poor one. The rich person possessed herds of cattle and many other flocks; and the poor one had one ewe that drank from his glass, ate from his table and slept in his embrace." Here Nathan revealed the genuine bond between a husband and wife. "When a certain stranger arrived, the rich man desired to keep his own animals, and he took the poor man's ewe and slaughtered her." Here, do you see how Nathan wove the dramatic act, mysteriously concealing the weapon in the glands of David's throat? Then what did the king say? Thinking that he had to pass judgment against someone else, he decided most severely. For such are human beings. When it concerns other people, they gladly and abruptly render decisions and publicize them. And what did David say? "As the Lord lives, the man who did this thing is worthy of death. And he shall restore the lamb fourfold." Therefore, what did Nathan reply? He did not allow the wound to be relieved for many hours; rather, he quickly stripped it naked and sharply embedded the knife deeply into it, so as not to rob it of the painful sensation. "You are the man, my king." What did the king say? "I have sinned against the Lord." He did not say, "Who are you who censures me? Who sent you to speak with such boldness? With what daring did you prevail?" He did not say anything of the sort; rather, he perceived the sin. And what did he say? "I have sinned against the Lord." Therefore, what did Nathan say to him? "And the Lord remitted your sin." You condemned yourself; I [God] remit your sentence. You confessed prudently; you annulled the sin. You appropriated a condemnatory decision against yourself; I repealed the sentence. Can you see that what is written in Scripture was fulfilled: "Be the first one to tell of your transgression so you may be justified" How toilsome is it to be the first one to declare the sin?”

“Now therefore the sword shall never depart from thine house,.... During his life, and as appeared in the slaughter of his sons Ammon and Absalom before his death, and of Adonijah quickly after, and in his posterity through their wars with the children of Israel, and other nations: because thou hast despised me; his commandments, and that in effect was despising him the lawgiver: and hast taken the wife of Uriah the Hittite to be thy wife; which being repeated shows that it was very displeasing to God, and a very heinous crime in his sight.”

“Thou hast killed Uriah - Thou art the Murderer, as having planned his death; the sword of the Ammonites was Thy instrument only.”

The in-app commentary runs from the Fathers to the early-modern record, then stops — that's where the public-domain sources end, not where the reading does. For the modern reading, follow the sources directly.
