16:16 Be well - And the success confirms their opinion. For although music cannot directly have an influence upon an evil spirit to drive him away; yet, because the devil, as it seems, had not possession of him, but only made use of the passions of his mind, and humours of his body to molest him: and because it is manifest, that music hath a mighty power to qualify and sweeten these, and to make a man sedate and chearful; it is not strange, if the devil had not that power over him when his mind was more composed, which he had when it was disordered; as the devil had less power over lunaticks in the decrease, than in the increase of the moon: Matt 17:15,18. And seeing music prepared the Lord's prophets for the entertainment of the good Spirit, as 2Kings 3:15. Why might it not dispose Saul to the resistance of the evil spirit? And why might not the chearing of his heart, in some measure strengthen him against those temptations of the devil, which were fed by his melancholy humour? And by this means, David without any contrivance of him or his friends, is brought to court, soon after he was anointed to the kingdom. Those whom God designs for any service, his providence will concur with his grace, to prepare and qualify them for it.
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.
