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. David kills two hundred Philistines in order to marry Michal, Saul's daughter. He is shown with one such Philistine's head in a cloth (we do not see the actual head).
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.
