1 Samuel 16:6-7

Amplified Bible

⁶ So it happened, when they had come, he looked at Eliab [the eldest son] and thought, “Surely the Lord’s anointed is before Him.” ⁷ But 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 ^[a]at the outward appearance, but the Lord looks at the heart.”
