“And it came to pass, when the evil spirit from God was upon Saul, that David took an harp, and played with his hand: so Saul was refreshed, and was well, and the evil spirit departed from him.”
King James Version (KJV)
16:23 Departed - Namely, for a season. And the reason of this success, may be, partly natural, and partly, supernatural, respecting David; whom God designed by this means to bring into favour with the king, and so to smooth the way for his advancement.
