2 Samuel 11

One spring, when kings go to war, David stays in Jerusalem, and from his roof he sees Bathsheba bathing. He takes her, commits adultery, and when she conceives, he tries to cover it by recalling her husband Uriah; when the loyal soldier refuses the comfort of home while his comrades camp in the field, David has Joab arrange his death in battle. He then marries the widow — “but the thing that David had done displeased the LORD.”
