The "evil" or "melancholy" spirit here spoken of was "the Spirit of God," or "of Jehovah," as being God's messenger and minister, sent by Him to execute His righteous purpose upon Saul (see 1 Kings 22:19-22 note).

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.

When Saul's attendants, i.e., his officers at court, perceived the mental ailment of the king, they advised him to let the evil spirit which troubled him be charmed away by instrumental music. "Let our lord speak (command); thy servants are before thee (i.e., ready to serve thee): they will seek a man skilled in playing upon the harp; so will it be well with thee when an evil spirit of God comes upon thee, and he (the man referred to) plays with his hands." The powerful influence exerted by music upon the state of the mind was well known even in the earliest times; so that the wise men of ancient Greece recommended music to soothe the passions, to heal mental diseases, and even to check tumults among the people. From the many examples collected by Grotius, Clericus, and more especially Bochart in the Hieroz. P. i. l. 2, c. 44, we will merely cite the words of Censorinus (de die natali, c. 12): "Pythagoras ut animum sua semper divinitate imbueret, priusquam se somno daret et cum esset expergitus, cithara ut ferunt cantare consueverat, et Asclepiades medicus phreneticorum mentes morbo turbatas saepe per symphoniam suae naturae reddidit."

And Saul's servants said unto him, Behold now, an evil spirit from God troubleth thee.

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.
