Here is biblical proof that great music from a righteous man can heal and restore. Praise God! 1 Samuel 16:17-23. So Saul said to his servants, “Provide me now a man who can play well, and bring him to me.” Then one of the servants answered and said, “Look, I have seen a son of Jesse the Bethlehemite, who is skillful in playing, a mighty man of valor, a man of war, prudent in speech, and a handsome person; and the LORD is with him.” Therefore Saul sent messengers to Jesse, and said, “Send me your son David, who is with the sheep.” And Jesse took a donkey loaded with bread, a skin of wine, and a young goat, and sent them by his son David to Saul. So David came to Saul and stood before him. And he loved him greatly, and he became his armorbearer. Then Saul sent to Jesse, saying, “Please let David stand before me, for he has found favor in my sight.” And so it was, whenever the spirit from God was upon Saul, that David would take a harp and play it with his hand. Then Saul would become refreshed and well, and the distressing spirit would depart from him.
