1 Samuel 16:6-7

6Upon their arrival, he saw Eliab and thought, “Surely, Adonai’s anointed one is before Him.”

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