Ahithophel is shown hanging from a self-made gallows.
Several stabbings, including Saul's suicide. Nothing too graphic is shown for the most part. In one disturbing scene, Jonathan is stabbed and shown with the spear stuck in his stomach. The stabbings of Amnon and Absalom show some blood. Scene with Absalom is particularly graphic.
One man is shot down by arrows, but nothing graphic is shown.
David is shown swinging the sword to cut off Goliath's head. Later, he carries his bloody head in a towel. Saul opens the towel and looks at the head. He jokingly thrusts it in his hands towards a young boy.
In one scene, Saul tries to pin Jonathan's head to a tree with a spear.
In a very brief scene, Saul hits his daughter in the face. We only see the back of her. No blood is shown.
