“If you like, however, I will give you further examples relating to our condition. Come then to the blessed David, and take him for your example of repentance. Great as he was, he suffered a fall. It was in the afternoon, after his siesta, that he took a turn on the housetop and saw by chance what stirred his human passion. He fulfilled the sinful deed, but his nobility, when it came to confessing the lapse, had not perished with the doing of the deed. Nathan the prophet came, swift to convict, but now as a healer for his wound, saying, "The Lord was angry, and you have sinned." So spoke a simple subject to his reigning sovereign. But David, though king and robed in purple, did not take it amiss, for he had regard not to the rank of the speaker but to the majesty of him who sent him. He was not puffed up by the fact that guardsmen were drawn up all around him, for the angelic host of the Lord came to his mind and he was in terror "as seeing him who is invisible." So he answered and said to the man that came to him, or rather, in his person, to the God whose messenger he was, "I have sinned against the Lord." You see this royal humility and the making of confession. Surely no one had been convicting him, nor were there many who knew what he had done. Swiftly the deed was done and immediately the prophet appeared as accuser. Lo! The sinner confesses his wicked deed, and as it was full and frank confession, he had the swiftest healing. For the prophet Nathan first threatened him, but then said immediately, "And the Lord has put away your sin." And see how quickly lovingkindness changes the face of God! Except that he first declares, "you have given great occasion to the enemies of the Lord to blaspheme" as though he said "you have many that are your foes because of your righteousness, from whom nevertheless, you were kept safe by your upright living. But as you have thrown away this best of armors, you have now, standing ready to strike, these foes that are risen up against you."So then the prophet comforted David as we have seen, but that blessed man, though he received most gladly the assurance, "The Lord has put away your sin," did not, king as he was, draw back from penitence. Indeed he put on sackcloth in place of his purple robe, and the king sat in ashes on the bare earth instead of on his gilded throne. And in ashes he did not merely sit, but took them for eating, as he himself says, "I have eaten ashes as it were bread, and mingled my drink with weeping." His lustful eye he wasted away with tears; as he says, "every night I wash my bed and water my couch with my tears." And when his courtiers exhorted him to eat food, he would not, but prolonged his fast for seven whole days.”

“Are you ashamed, sir, to do as David did—David, the king and the prophet, the ancestor of Christ according to the flesh? He was told of the rich man who had a great number of flocks and yet, when a guest arrived, took the poor man's one ewe lamb and killed it; and when he recognized that he was himself condemned by the story, he said, "I have sinned against the Lord." Therefore do not take it ill, sir, if what was said to King David is said to you, "You are the man." For if you listen with attention and say, "I have sinned against the Lord," if you say, in the words of the royal prophet, "O come, let us worship and fall down, and weep before the Lord our Maker," then it will be said to you also, "Because you repented, the Lord has put away your sin; you shall not die."”

“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?”

“Indeed, to the penitent himself confession alone does not suffice, unless correction of the deed follows, with the result that the penitent does not continue to do deeds which demand repentance. He should even humble his soul just as holy David, who, when he heard from the prophet: "Your sin is pardoned," became more humble in the correction of his sin, so that "he did eat ashes like bread and mingled his drink with weeping."”

“But just as Matthew, presenting Christ the king as if descending for the assumption of our sins, thus descends from David through Solomon, because Solomon was born of her with whom David had sinned, so Luke, presenting Christ the priest as if ascending after the destroying of sins, ascends through Nathan to David, because Nathan the prophet had been sent, and by his reproof the penitent David obtained the annulling of his sin.”

“Similarity of words, dissimilarity of hearts. We may hear the similarity of the words with our ears, but we can only know the dissimilarity of hearts by the angel's declaration. David sinned, and when he was rebuked by the prophet, he said, "I have sinned," and was immediately told, "Your sin has been forgiven you." Saul sinned, and when he was rebuked by the prophet, he said, "I have sinned," and his sin was not forgiven, but the wrath of God remained upon him. What can this mean but similarity of words, dissimilarity of hearts? Human beings can hear words, God inspects hearts.”

“Baptized people, though, who are deserters and violators of such a great sacrament, if they repent from the bottom of their hearts, if they repent where God can see, as he saw David's heart, when on being rebuked by the prophet, and very sternly rebuked, he cried out after hearing God's fearsome threats and said, "I have sinned," and shortly afterward heard, "God has taken away your sin." Such is the effectiveness of three syllables. "I have sinned" is just three syllables; and yet in these three syllables the flames of the heart's sacrifice rose up to heaven. So those who have done genuine penance, and have been absolved from the constraints by which they were bound and cut off from the body of Christ, and have lived good lives after their penance, such as they ought to have lived before penance, and in due course have passed away after being reconciled, why, they too go to God, go to their rest, will not be deprived of the kingdom, will be set apart from the people of the devil.”

“Howbeit, because by this deed,.... This complicated wickedness, adultery with Bathsheba, and the murder of her husband, and occasioning the death of others: thou hast given great reason to the enemies of the Lord to blaspheme; to insult over Israel, and the God of Israel, and to magnify their own idols on account of the advantage they got when Uriah and other Israelites were slain; and to speak ill of God as a respecter of persons, who had cast off Saul and his family from the kingdom, and yet established David in it, guilty of crimes the other was not; and of the word, ways, and worship of God, and of the true religion, as all hypocrisy and deceit, when men that made such pretensions to it were guilty of such atrocious crimes; wherefore to let such see and know that the Lord did not approve of and countenance such actions, but abhorred and resented them: the child also that is born unto thee shall surely die; which would be a visible testimony of God's displeasure at his sin, to all men that should hear of it, and know it; and being taken away in such a manner would be a great affliction to him, and the more as his affections were much towards the child, as appears by what follows; or otherwise the removal of it might have been considered as a mercy, since its life would have kept up the remembrance of the sin, and have been a standing reproach to him.”

“The Lord - hath put away thy sin - Many have supposed that David's sin was now actually pardoned, but this is perfectly erroneous; David, as an adulterer, was condemned to death by the law of God; and he had according to that law passed sentence of death upon himself. God alone, whose law that was could revoke that sentence, or dispense with its execution; therefore Nathan, who had charged the guilt home upon his conscience, is authorized to give him the assurance that he should not die a temporal death for it: The Lord hath put away thy sin; thou shalt not die. This is all that is contained in the assurance given by Nathan: Thou shalt not die that temporal death; thou shalt be preserved alive, that thou mayest have time to repent, turn to God, and find mercy. If the fifty-first Psalm, as is generally supposed, was written on this occasion, then it is evident (as the Psalm must have been written after this interview) that David had not received pardon for his sin from God at the time he composed it; for in it he confesses the crime in order to find mercy. There is something very remarkable in the words of Nathan: The Lord also hath Put Away thy sin; thou shalt not die; גם יהוה העביר חטאתך לא תמות gam Yehovah heebir chattathecha lo thamuth, Also Jehovah Hath Caused thy sin To Pass Over, or transferred thy sin; Thou shalt not die. God has transferred the legal punishment of this sin to the child; He shall die, Thou shalt not die; and this is the very point on which the prophet gives him the most direct information: The child that is born unto thee shall Surely die; מות ימות moth yamuth, dying he shall die - he shall be in a dying state seven days, and then he shall die. So God immediately struck the child, and it was very sick.”

“Sinned. His confession was sincere, and very different from that of Saul, 1 Kings xv. 24. “The expression was the same; but God saw the difference of the heart.” (St. Augustine, contra Faust. xxii. 27.) — Sin. He has remitted the fault and the eternal punishment, and he has greatly diminished the temporal chastisement, and will not inflict instant death, as he seemed to have threatened, ver. 10. (Calmet) — “The speedy remission shewed the greatness of the king’s repentance.” (St. Ambrose, Apol. 2.)”
