Nathan tells David a story about a rich man who takes a poor man's only lamb to feed a traveler rather than take from his own flock. David is outraged at the injustice and says the man deserves to die. Nathan then reveals that David is the man - he took Uriah's wife Bathsheba after having him killed. David acknowledges his sin. Nathan says God has forgiven David's sin against him, but the child born from this sinful relationship will die as a consequence of David's actions.
