1 Samuel 16:19-22

Wherefore Saul sent messengers unto Jesse, and said, Send me David thy son, which is with the sheep. And Jesse took an ass laden with bread, and a bottle of wine, and a kid, and sent them by David his son unto Saul. And David came to Saul, and stood before him: and he loved him greatly; and he became his armourbearer. And Saul sent to Jesse, saying, Let David, I pray thee, stand before me; for he hath found favour in my sight.
