Goliath
Goliath is described in the biblical Book of Samuel as a Philistine giant defeated by the young David in single combat. The story signified Saul's unfitness to rule, as Saul himself should have fought for the Kingdom of Israel.
The Bible and violence
War comes again, David is victorious. Saul again wants to kill David, and he flees with help from his wife. Saul searches for him and slays the inhabitants of the city Nob for aiding David (1 Samuel 22). David defeats the Philistines at Keilah, then flees the city pursued by Saul (1 Samuel 22). David and Saul reconcile. David seeks refuge with Achish, king of Gath, and claims he is raiding Judah but is actually raiding and killing in other places (1 Samuel 27). The Philistines begins a war against Saul. David's wives Ahinoam and Abigail are taken in a raid on Ziklag, but he rescue them (1 Samuel 30). The men of Israel flee before the Philistines, and three of Saul's sons are slain. Saul asks his armour-bearer to kill him, but is refused, so he takes his own life. The armour-bearer also takes his own life. Saul's body is beheaded and fastened to a city-wall by the victorious Philistines, but it is retaken by inhabitants of Jabesh-Gilead (1 Samuel 30).
