It happened, when the [evil] spirit from God was on Saul, that David took the harp, and played with his hand: so Saul was refreshed, and was well, and the evil spirit departed from him.
"This story of how David first met Saul and how he came to the royal court makes two points. The first is that David did not engineer it. David was no ruthlessly ambitious man, determined to rise up the social ladder-any more than Saul himself had been (cp. chapter 9). David’s hands were clean. The second point is that God overruled to bring David to court, through the sheer chance (as it seemed) that one of Saul’s courtiers knew something about him and brought him to Saul’s attention [cf. Joseph]. So it was God, not David, who was responsible for the young man’s first steps towards the throne." [Note: David Payne, p. 85.]
