1 Samuel 16:14-16

Now the Spirit of the LORD had left Saul, and the LORD sent a tormenting spirit that filled him with depression and fear. Some of Saul’s servants said to him, “A tormenting spirit from God is troubling you. Let us find a good musician to play the harp whenever the tormenting spirit troubles you. He will play soothing music, and you will soon be well again.”
