David Gets Distracted, II Samuel 10-11, OT S1:E178

When he should have been at war, David instead stays in Jerusalem. He who was mighty in battle proves weak in temptation. Succumbing to the beauty of Bathsheba, he has an affair with her. Uriah, Bathsheba's husband, is the hero of this story. Loyal to the end, he is slain by the king he served, who slept with his wife, in an attempted cover-up.
