1 Samuel 16:6-9

6So it happened, when they had come, he looked at Eliab [the eldest son] and thought, “Surely the Lord’s anointed is before Him.”

7But the Lord said to Samuel, “Do not look at his appearance or at the height of his stature, because I have rejected him. For the Lord sees not as man sees; for man looks at the outward appearance, but the Lord looks at the heart.”

8Then Jesse called Abinadab and had him pass before Samuel. But Samuel said, “The Lord has not chosen this one either.”

9Next Jesse had Shammah pass by. And Samuel said, “The Lord has not chosen him either.”
