1 Samuel 16:23

And whenever the spirit from God came upon Saul, David would pick up his harp and play. Then Saul would find relief and feel better, and the spirit of distress would depart from him.

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.
