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.
Saul og David
Abner interrupts David, who is singing for Saul, and announces the challenge of the Philistine champion Goliath. Saul promises Michal's hand to whoever can defeat Goliath. David undertakes the challenge and succeeds. Saul immediately becomes jealous of the adulation David receives, and David flees to escape the king's anger.
