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
A man tells David of Saul's death and that he himself killed Saul. David has him killed (2 Samuel 1). A long war starts between David and Saul's son Ish-bosheth (2 Samuel 3). David demands and is granted the return of his first wife Michal, despite the public grief of her new husband Palti. Two men assassinate Ish-bosheth, and David has them killed (2 Samuel 4). David wars victoriously with the Philistines. While transporting the Ark of the Covenant to Jerusalem, a man called Uzzah carelessly touches it and is killed by God (2 Samuel 6).
