“But the Lord said to Samuel, ‘Do not look at his appearance or his stature, because I have rejected him. Man does not see what the Lord sees, for man sees what is visible, but the Lord sees the heart'” (1 Samuel 16:7, HCSB).
In 1 Samuel 16:1 God told Samuel to go and anoint David as the new king over Israel. From biblical descriptions, David and Saul had contrasting appearances. Saul was tall and striking in appearance while David was a young boy with a ruddy appearance.
