2 Kings 12:4

Plainly, if you show by what patronages of heavenly precedents and precepts it is that you open to adultery alone, and therein to fornication also, the gate of repentance, at this very line our hostile encounter will forthwith cross swords. Yet I must necessarily prescribe you a law, not to stretch out your hand after the old things, not to look backwards: for “the old things are passed away,” according to Isaiah; and “a renewing hath been renewed,” according to Jeremiah; and “forgetful of former things, we are reaching forward,” according to the apostle; and “the law and the prophets (were) until John,” according to the Lord. …

31. And with what moderation and self-restraint those men used their wives appears chiefly in this, that when this same king, carried away by the heat of passion and by temporal prosperity, had taken unlawful possession of one woman, whose husband also he ordered to be put to death, he was accused of his crime by a prophet, who, when he had come to show him his sin, set before him the parable of the poor man who had but one ewe-lamb, and whose neighbor, though he had many, yet when a guest came to him spared to take of his own flock, but set his poor neighbor’s one lamb before his guest to eat. And David’s anger being kindled against the man, he commanded that he should be put to death, and the lamb restored fourfold to the poor man; thus unwittingly condemning the sin he had wittingly committed. …

12. In this way, it is the taking of our sins upon Himself by the Lord Christ that is signified in the genealogy of Matthew, while in the genealogy of Luke it is the abolition of our sins by the Lord Christ that is expressed. In accordance with these ideas, the one details the names in the descending scale, and the other in the ascending. For when the apostle says, “God sent His Son in the likeness of the flesh of sin,” he refers to the taking of our sins upon Himself by Christ. But when he adds, “for sin, to condemn sin in the flesh,” he expresses the expiation of sins. Consequently Matthew traces the succession downwards from David through Solomon, in connection with whose mother it was that he sinned; while Luke carries the gene alogy upwards to the same David through Nathan, by which prophet God took away his sin. …

Sometimes, however, even a proud rich man is to be propitiated by blandishment in exhortation, since hard sores also are usually softened by soothing fomentations, and the rage of the insane is often restored to health by the bland words of the physician, and, when they are pleasantly humoured, the disease of their insanity is mitigated. For neither is this to be lightly regarded, that, when an adverse spirit entered into Saul, David took his harp and assuaged his madness ( 1 Sam. xviii. 10 ). For what is intimated by Saul but the elation of men in power, and what by David but the humble life of the holy? When, then, Saul is seized by the unclean spirit, his madness is appeased by David’s singing; since, when the senses of men in power are turned to frenzy by elation, it is meet that they should be recalled to a healthy state by the calmness of our speech, as by the sweetness of a harp. …
