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.
Names and titles of Jesus in the New Testament
The title "Son of David" indicates Jesus' physical descent from David, as well as his membership of the Davidic line of kings. The phrase is used a number of times in the gospel of Matthew. It appears in to introduce both the genealogy and the gospel. It is found on the lips of the blind men healed in Galilee ("Have mercy on us, Son of David", ), the crowd who are amazed at Jesus' healing of a blind, mute and demon-possessed man ), the Canaanite woman whose daughter is exorcised ("Lord, Son of David, have mercy on me," ), and the blind men healed near Jericho ("Lord, Son of David, have mercy on us", ). Finally, it also forms part of the shout of the crowds when Jesus enters Jerusalem: "Hosanna to the Son of David" (Matthew 21:9).
