Goliath is the biblical giant of Gath, Philistine. Representing the Philistines, he challenged the Israelites to send a champion against him so that the war between the two tribes might be settled by single combat. David, the youthful champion of the Israelites rose to the challenge and killed Goliath with a single sling shot. David later became the King of Israel. This story is used as a parable to show that skill and can win over brawn.
