1 Samuel 16:19-23

19. Wherefore Saul sent messengers unto Jesse, and said, Send me David thy son, which [is] with the sheep. 20. 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. 21. And David came to Saul, and stood before him: and he loved him greatly; and he became his armourbearer. 22. And Saul sent to Jesse, saying, Let David, I pray thee, stand before me; for he hath found favour in my sight. 23. And it came to pass, when the [evil] spirit from God was upon Saul, that David took an harp, and played with his hand: so Saul was refreshed, and was well, and the evil spirit departed from him.
