The study discusses the Old Testament's parable of Nathan and the subsequent condemnation of King David. The intriguing episode of the Prophet Nathan pronouncing judgment on the erring King David has always attracted the interest of the exegete and various researchers have used different methods to separate the condemnation of King David from the ancient author. This study presents a synchronic reading of the canonical text that reveals the episode as the mirror image of the oracle of eternal dynasty pronounced to David by the same prophet in the Second Book of Samuel 7. It is indeed the work of the deuteronomistic writer who has adapted an oracle against the dynasty of David and trimmed it to the advantage of his hero in the unfolding of history.
