1 Samuel 16:21-23

American Standard Version

²¹ And David came to Saul, and stood before him: and he loved him greatly; and he became his armorbearer. ²² And Saul sent to Jesse, saying, Let David, I pray thee, stand before me; for he hath found favor in my sight. ²³ And it came to pass, when the evil spirit from God was upon Saul, that David took the harp, and played with his hand: so Saul was refreshed, and was well, and the evil spirit departed from him.
