I Samuel 16:11-13

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.
