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.
Internal consistency of the Bible
Internal consistency within the synoptic gospels has been analysed by many scholars. A well-known example is the nativity narratives found in the Gospel of Matthew () and the Gospel of Luke (). Each gives a genealogy of Jesus, but the names, and even the number of generations, differ between the two. Apologists have suggested that the differences are the result of two different lineages, Matthew's from King David's son, Solomon, to Jacob, father of Joseph, and Luke's from King David's other son, Nathan, to Heli, father of Mary and father-in-law of Joseph. However, Geza Vermes points out that Luke makes no mention of Mary, and questions what purpose a maternal genealogy would serve in a Jewish setting.
