I Samuel 16:14-16

But the Spirit of the LORD departed from Saul, and a distressing spirit from the LORD troubled him. And Saul’s servants said to him, “Surely, a distressing spirit from God is troubling you. Let our master now command your servants, who are before you, to seek out a man who is a skillful player on the harp. And it shall be that he will play it with his hand when the distressing spirit from God is upon you, and you shall be well.”
