(15) An evil spirit from God.--The form in which the evil spirit manifested itself in Saul was apparently an incurable melancholy, which at times blazed forth in fits of uncontrollable jealous anger. When Saul's attendants, his officers, and those about his person, perceived the mental malady under which their king was evidently suffering, they counselled that he should try whether the evil influence which troubled him could not be charmed away by music.

There is no doubt but that King Saul's nervous, excitable temperament was peculiarly subject to such influences. We have some striking instances of this power exercised by sacred music over the king in the incidents related in 1Samuel 10:10; 1Samuel 19:23-24, where the songs and chaunts of the pupils of the prophetic schools had so powerful an influence over Saul. The solemn declaration of God through his prophet Samuel, that the kingdom was taken away from him and his house, weighed upon his naturally nervous and excitable mind. He became gloomy, and suspicious of his dearest friends, and, as we know, at times sought to take their lives; at times would command terrible massacres, such as that of the priests at Nob (1Samuel 22:17-19). As the sad life advanced, we see the nobler traits in his character growing fainter, and the evil becoming more and more obvious. It was a species of insanity, fatal alike to the poor victim of the malady and to the prosperity of the kingdom over which he ruled. History gives us not a few similar instances of monarchs given up to the "evil spirit from God," and who, in consequence, became a prey to insanity in one form or other.

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.And Saul's servants said unto him,.... His courtiers, who observing him to act in a frantic manner, to be dull and melancholy, timorous, and irresolute, unsteady, divided, and distressed; or his physicians, who were called in to assist him, and remove his disorder from him:

behold, now an evil spirit from God troubleth thee: the disorder was not from any natural cause, or any bodily disease, and therefore out of the reach of physicians to do any service, but was from an evil spirit suffered of God to harass and disturb him.
