14 But the Spirit of the Lord departed from Saul, and a distressing spirit from the Lord troubled him. 15 And Saul's servants said to him, "Surely, a distressing spirit from God is troubling you. 16 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." 17 So Saul said to his servants, "Provide me now a man who can play well, and bring him to me." 18 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." 19 Therefore Saul sent messengers to Jesse, and said, "Send me your son David, who is with the sheep." 20 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. 21 So David came to Saul and stood before him. And he loved him greatly, and he became his armorbearer. 22 Then Saul sent to Jesse, saying, "Please let David stand before me, for he has found favor in my sight." 23 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.

Commentary on 1 Samuel 16:14-23
(Read 1 Samuel 16:14-23)
Saul is made a terror to himself. The Spirit of the Lord departed from him. If God and his grace do not rule us, sin and Satan will have possession of us. The devil, by the Divine permission, troubled and terrified Saul, by the corrupt humours of his body, and passions of his mind. He grew fretful, peevish, and discontented, and at times a madman. It is a pity that music, which may be serviceable to the good temper of the mind, should ever be abused, to support vanity and luxury, and made an occasion of drawing the heart from God and serious things. That is driving away the good Spirit, not the evil spirit. Music, diversions, company, or business, have for a time often been employed to quiet the wounded conscience; but nothing can effect a real cure but the blood of Christ, applied in faith, and the sanctifying Spirit sealing the pardon, by his holy comforts. All other plans to dispel religious melancholy are sure to add to distress, either in this world or the next.
