Saul's Envy
Saul is enraged and envious when the victorious David, bearing the head of Goliath, receives greater praise than he. "Saul slew his thousands," the Israelite women sing, "and David his ten thousands." (1 Kings 18:6–9)
Madness
Later, as David plays for Saul, the evil spirit re-enters the king's ear. Saul aims a spear at David, who neatly steps aside and avoids the blow. Now, the king is sure that the Lord has given his favor to David. (1 Kings 18:10–11)
A Dangerous Post
His fear of David mounting, Saul schemes to rid himself of the young warrior by bestowing upon him the dangerous duty of captaining a thousand men. (1 Kings 18:12–14)
