King Saul and the Israelite army face seemingly impossible odds against the Philistine army and their champion, Goliath. An unlikely here, the young David, defeats Goliath and goes on to lead the Israelites to victory against the Philistines. Saul fears that David means to steal his throne and so betrays his loyal warrior. This is Saul's undoing, and David becomes King and later captures Jerusalem for the Israelites.
