11 And Samuel said to Jesse, "Are all your sons here?" And he said, "There remains yet the youngest, but behold, he is keeping the sheep." And Samuel said to Jesse, "Send and fetch him; for we will not sit down till he comes here."

13 Then Samuel took the horn of oil, and anointed him in the midst of his brothers; and the Spirit of the LORD came mightily upon David from that day forward. And Samuel rose up, and went to Ramah.
