1 Samuel 16:6-7

6So it was, when they came, that he looked at Eliab and said, “Surely the Lord’s anointed is before Him!”

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