“Let our lord now command thy servants, which are before thee, to seek out a man, who is a cunning player on an harp: and it shall come to pass, when the evil spirit from God is upon thee, that he shall play with his hand, and thou shalt be well.”
King James Version (KJV)
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.
