18 And one of the servants answereth and saith, 'Lo, I have seen a son of Jesse the Beth-Lehemite, skilful in playing, and a mighty virtuous man, and a man of battle, and intelligent in word, and a man of form, and Jehovah 'is' with him.' 19 And Saul sendeth messengers unto Jesse, and saith, 'Send unto me David thy son, who 'is' with the flock.' 20 And Jesse taketh an ass, 'with' bread, and a bottle of wine, and one kid of the goats, and sendeth by the hand of David his son unto Saul. 21 And David cometh in unto Saul, and standeth before him, and he loveth him greatly; and he is a bearer of his weapons. 22 And Saul sendeth unto Jesse, saying, 'Let David, I pray thee, stand before me, for he hath found grace in mine eyes.' 23 And it hath come to pass, in the spirit of 'sadness from' God being on Saul, that David hath taken the harp, and played with his hand, and Saul hath refreshment and gladness, and the spirit of sadness hath turned aside from off 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.
