1 Samuel 16:6-13

And it came to pass, when they were come, that he looked on Eliab, and said, Surely Jehovah’s anointed is before him. But Jehovah said unto Samuel, Look not on his countenance, or on the height of his stature; because I have rejected him: for Jehovah seeth not as man seeth; for man looketh on the outward appearance, but Jehovah looketh on the heart. Then Jesse called Abinadab, and made him pass before Samuel. And he said, Neither hath Jehovah chosen this. Then Jesse made Shammah to pass by. And he said, Neither hath Jehovah chosen this. And Jesse made seven of his sons to pass before Samuel. And Samuel said unto Jesse, Jehovah hath not chosen these. And Samuel said unto Jesse, Are here all thy children? And he said, There remaineth yet the youngest, and, behold, he is keeping the sheep. And Samuel said unto Jesse, Send and fetch him; for we will not sit down till he come hither. And he sent, and brought him in. Now he was ruddy, and withal of a beautiful countenance, and goodly to look upon. And Jehovah said, Arise, anoint him; for this is he. Then Samuel took the horn of oil, and anointed him in the midst of his brethren: and the Spirit of Jehovah came mightily upon David from that day forward. So Samuel rose up, and went to Ramah.
