14 Now the Spirit of the Lord departed from Saul, and a harmful spirit from the Lord tormented him.
14 At that very moment the Spirit of God left Saul and in its place a black mood sent by God settled on him. He was terrified.
14 But the Spirit of the Lord departed from Saul, and a distressing spirit from the Lord troubled him.
14 Now the Spirit of the Lord had left Saul, and the Lord sent a tormenting spirit that filled him with depression and fear.
Matthew Henry's Commentary on 1 Samuel 16:14
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.
