1 Samuel 16:16-23

16 Let our lord now command your servants who are before you, to seek out a man who is a skillful player on the harp: and it shall happen, when the evil spirit from God is on you, that he shall play with his hand, and you shall be well.
17 Sha'ul said to his servants, Provide me now a man who can play well, and bring him to me.
18 Then answered one of the young men, and said, Behold, I have seen a son of Yishai the Beit-Hallachmite, who is skillful in playing, and a mighty man of valor, and a man of war, and prudent in speech, and a comely person; and the LORD is with him.
19 Therefore Sha'ul sent messengers to Yishai, and said, Send me David your son, who is with the sheep.
20 Yishai took a donkey [laden] with bread, and a bottle of wine, and a kid, and sent them by David his son to Sha'ul.
21 David came to Sha'ul, and stood before him: and he loved him greatly; and he became his armor bearer.
22 Sha'ul sent to Yishai, saying, Please let David stand before me; for he has found favor in my sight.
23 It happened, when the [evil] spirit from God was on Sha'ul, that David took the harp, and played with his hand: so Sha'ul was refreshed, and was well, and the evil spirit departed from him.
