2 Samuel 12:7

Thou art the man! Abruptly and with sudden vehemence comes the application to David himself. So skilfully had the parable been contrived, that up to this point David had had no suspicion that he was the rich man who had acted so meanly by his poorer neighbour Uriah. And now he stood self-condemned. Yet even so self-love might have made his indignation break forth against Nathan; but probably the reproof only completed a work that had long been secretly in progress, and brushed away the last obstacles to repentance. I anointed thee. The solemn anointing made David the representative of Jehovah, and thus his sin was aggravated by the degradation in the eyes of the people, beth of the kingly office and also of Jehovah himself. Rank and authority are given to men that they may lead others to do right; it is a fearful misuse of them when they give prestige to sin.
