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.
Jewish mythology
David and Goliath confront each other, Goliath with his armor and javelin, David with his staff and sling. David hurls a stone from his sling and hits Goliath in the center of his forehead, Goliath falls on his face to the ground, and David cuts off his head. The Philistines flee and are pursued by the Israelites "as far as Gath and the gates of Ekron". David puts the armor of Goliath in his own tent and takes the head to Jerusalem, and Saul sends Abner to bring the boy to him. The king asks whose son he is, and David answers, "I am the son of your servant Jesse the Bethlehemite."
