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.
Khirbet Qeiyafa
Yigal Levin has proposed that the ma'gal (מעגל) or "circular camp" of the Israelites which is mentioned in the story of David and Goliath () was described this way because it fitted the circular shape of the nearby Khirbet Qeiyafa. Levin argues that the story of David and Goliath is set decades before Khirbet Qeiyafa was built and so the reference to Israel's encampment at the ma'gal probably does "not represent any particular historical event at all". But when the story was composed centuries later, the round structure of Khirbet Qeiyafa "would still have been visible and known to the author of ", who "guessed its function, and worked it into his story".
