1 Samuel 16:10

But the LORD said to Samuel, “Don’t look on his face, or on the height of his stature, because I have rejected him; for I don’t see as man sees. For man looks at the outward appearance, but the LORD looks at the heart.”

Then Jesse called Abinadab, and made him pass before Samuel. He said, “The LORD has not chosen this one, either.”

Then Jesse made Shammah to pass by. He said, “The LORD has not chosen this one, either.”

Samuel said to Jesse, “Are all your children here?”

He said, “There remains yet the youngest. Behold, he is keeping the sheep.”

Samuel said to Jesse, “Send and get him, for we will not sit down until he comes here.”

He sent, and brought him in. Now he was ruddy, with a handsome face and good appearance. The LORD said, “Arise! Anoint him, for this is he.”

Then Samuel took the horn of oil and anointed him in the middle of his brothers. Then the LORD’s Spirit came mightily on David from that day forward. So Samuel rose up and went to Ramah.
