As long as that son of Jesse is alive, you'll never be king. Now fo and get him so I can kill him! - 1 Samuel 20:31
Few emotions can harm our hearts and relationships like uncontrolled anger
Anger led to:
Saul's anger erupted out of jealousy of David's popularity and treat of becoming king
His anger was so fierce and overwhelming that he attempted to kill David at least three times
Saul's anger made it to his son Jonathan because he was tried to protect David
Saul showed his true colors when he allowed anger to control his every motivation, decision, and action
