music for saul troubled spirit troubling spirit

In 1 Samuel 16-17, we are introduced to David as King. In chapter 16, Samuel is told by God to stop grieving over Saul, and to head out to the family of Jesse and anoint one of his sons as King. After David is anointed, we see Saul struggling with a distressing spirit from the Lord, and only David can soothe Saul's troubled heart through his music. In chapter 17, we see David face off against Goliath. David is displayed as an example of Christ slaying our enemies of satan, sin, and death, through the power of God.
