What does the Bible say about the anointing of David?

In 1 Samuel 16, we see God reject Saul as king and instruct Samuel to anoint David, the youngest son of Jesse. This event signifies God's sovereignty in choosing leaders based on the heart rather than outward appearance. David, described as ruddy and handsome, was chosen because he was a man after God's own heart. The anointing marked the beginning of God's Spirit empowering David to fulfill his role as king, demonstrating the principle that true leadership is granted by divine selection and empowerment. This represents a broader theme of God's grace in using the least likely candidates to fulfill His purposes.
