Nathan was the prophet who confronted King David about his sin involving Bathsheba. He challenged the king after David took Bathsheba, the wife of Uriah the Hittite, and arranged for Uriah to die in battle.
Nathan approached David with a parable about a wealthy man who seized a poor man’s only beloved lamb. David reacted with outrage at the injustice, but Nathan then revealed that the story represented David’s own conduct. The confrontation forced David to acknowledge his guilt, and Nathan announced consequences for the royal household while also declaring that David would not die for the sin.
Nathan was more than a critic. Earlier, he had advised David about plans for a temple and delivered a promise concerning David’s dynasty. Near the end of David’s life, Nathan helped ensure that Solomon succeeded him rather than Adonijah. Samuel and Gad were also prophets connected with David’s reign, but Nathan is the specific prophet who rebuked David over Bathsheba and Uriah.
