1 Samuel 16:6-7 English Standard Version (ESV)

6 When they came, he looked on Eliab and thought, “Surely the Lord's anointed is before him.” 7 But the Lord said to Samuel, “Do not look on his appearance or on the height of his stature, because I have rejected him. For the Lord sees not as man sees: man looks on the outward appearance, but the Lord looks on the heart.”
