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.
Goliath
Saul and the Israelites are facing the Philistines in the Valley of Elah. Twice a day for 40 days, morning and evening, Goliath, the champion of the Philistines, comes out between the lines and challenges the Israelites to send out a champion of their own to decide the outcome in single combat, but Saul is afraid. David, bringing food for his elder brothers, hears that Goliath has defied the armies of God and of the reward from Saul to the one that defeats him, and accepts the challenge. Saul reluctantly agrees and offers his armor, which David declines, taking only his staff, sling and five stones from a brook.
