1 Samuel 16:14-17

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.” “All right,” Saul said. “Find me someone who plays well, and bring him here.”
