14 Now the Spirit of the Lord departed from Saul, and a harmful spirit from the Lord tormented him. 15 And Saul's servants said to him, "Behold now, a harmful spirit from God is tormenting you. 16 Let our lord now command your servants who are before you to seek out a man who is skillful in playing the lyre, and when the harmful spirit from God is upon you, he will play it, and you will be well." 17 So Saul said to his servants, "Provide for me a man who can play well and bring him to me." 18 One of the young men answered, "Behold, I have seen a son of Jesse the Bethlehemite, who is skillful in playing, a man of valor, a man of war, prudent in speech, and a man of good presence, and the Lord is with him." 19 Therefore Saul sent messengers to Jesse and said, "Send me David your son, who is with the sheep." 20 And Jesse took a donkey laden with bread and a skin of wine and a young goat and sent them by David his son to Saul. 21 And David came to Saul and entered his service. And Saul loved him greatly, and he became his armor-bearer. 22 And Saul sent to Jesse, saying, "Let David remain in my service, for he has found favor in my sight." 23 And whenever the harmful spirit from God was upon Saul, David took the lyre and played it with his hand. So Saul was refreshed and was well, and the harmful spirit departed 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.
