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.
Moresheth-Gath
The name Moreseth-Gath means “possession of Gath"; Gath was the city of origin of Goliath, so it has been speculated that Moresheth held a subservient relationship with the Philistine city.
However, among Jewish commentators, only Abraham ibn Ezra and David Kimhi consider Moresheth-gath as the name of a place. The Targum of Jonathan and Rashi translate these two words as by "those who caused you to inherit Gath" meaning the family of David, while Wellhausen renders the passage in Micah "Thou must let go Moresheth, O Gath."
