What does the Bible say about David and Saul?

The relationship between David and Saul reflects a profound theological truth of God's sovereignty in choosing his leaders. In 1 Samuel 26, we see how God delivered Saul into David's hands, yet David, acknowledging Saul as the Lord's anointed, refrained from harming him. This act exemplifies David's reverence for God's sovereign appointment of authority. Saul was chosen by the people, representing a flawed human choice, while David was God's anointed, illustrating the divine choice of leadership. This narrative teaches us that true authority and power are established by God, and that we are to honor His sovereign will.
