This is the story of David and Bathsheba. David's escapade (a misstep in an otherwise stellar testimony) illustrates James 1:15 with agonizing clarity. "When lust has conceived, it brings forth sin: and sin, when it is finished, brings forth death." You have likely heard the digression described before. David was in the wrong place at the wrong time. He saw his beautiful neighbor Bathsheba in some stage of indecency. He looked; he lusted; he yielded to the temptation; he invited her over; she came; he committed adultery with her; he went to great lengths to cover his tracks; many people died because of David's tryst.
Although Uriah (Bathsheba's husband) was one of David's mightiest and most loyal military specialists (II Samuel 23:8 & 39), David ended up killing him. Then, the son who was born from their sinful union was slain by God as part of the David's punishment (II Samuel 12:14). And, several Jewish soldiers died during the cover-up of Uriah's murder (2 Samuel 11:17). Additionally, as you watch David's biography unfold, you will find that death dominated his household in accordance with II Samuel 12:10, where God said, "The sword shall never depart from your house; because you have despised me, and have taken the wife of Uriah the Hittite to be your wife." In short, "The wages of sin is death" (Romans 6:23).
