1 Samuel 16:6-13 King James Version (KJV)
6 And it came to pass, when they were come, that he looked on Eliab, and said, Surely the Lord's anointed is before him.
7 But the Lord said unto Samuel, Look not on his countenance, or on the height of his stature; because I have refused him: for the Lord seeth not as man seeth; for man looketh on the outward appearance, but the Lord looketh on the heart.
8 Then Jesse called Abinadab, and made him pass before Samuel. And he said, Neither hath the Lord chosen this.
9 Then Jesse made Shammah to pass by. And he said, Neither hath the Lord chosen this.
10 Again, Jesse made seven of his sons to pass before Samuel. And Samuel said unto Jesse, The Lord hath not chosen these.
11 And Samuel said unto Jesse, Are here all thy children? And he said, There remaineth yet the youngest, and, behold, he keepeth the sheep. And Samuel said unto Jesse, Send and fetch him: for we will not sit down till he come hither.
12 And he sent, and brought him in. Now he was ruddy, and withal of a beautiful countenance, and goodly to look to. And the Lord said, Arise, anoint him: for this is he.
13 Then Samuel took the horn of oil, and anointed him in the midst of his brethren: and the Spirit of the Lord came upon David from that day forward. So Samuel rose up, and went to Ramah.
