I Samuel 16:6-13

So it was, when they came, that he looked at Eliab and said, “Surely the LORD’s anointed is before Him!” But 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.” So Jesse called Abinadab, and made him pass before Samuel. And he said, “Neither has the LORD chosen this one.” Then Jesse made Shammah pass by. And he said, “Neither has the LORD chosen this one.” Thus Jesse made seven of his sons pass before Samuel. And Samuel said to Jesse, “The LORD has not chosen these.” And Samuel said to Jesse, “Are all the young men here?” Then he said, “There remains yet the youngest, and there he is, keeping the sheep.” And Samuel said to Jesse, “Send and bring him. For we will not sit down till he comes here.” So he sent and brought him in. Now he was ruddy, with bright eyes, and good-looking. And the LORD said, “Arise, anoint him; for this is the one!” Then Samuel took the horn of oil and anointed him in the midst of his brothers; and the Spirit of the LORD came upon David from that day forward. So Samuel arose and went to Ramah.
