1 Samuel 16:12-14 New Revised Standard Version (NRSV)
12 He sent and brought him in. Now he was ruddy, and had beautiful eyes, and was handsome. The Lord said, “Rise and anoint him; for this is the one.” 13 Then Samuel took the horn of oil, and anointed him in the presence of his brothers; and the spirit of the Lord came mightily upon David from that day forward. Samuel then set out and went to Ramah.
