1 Samuel 16:19-23

MLV(i) 19 Therefore Saul sent messengers to Jesse and said, Send to me David your son, who is with the sheep. 20 And Jesse took a donkey with bread and a skin-container of wine and a kid and sent them by David his son to Saul. 21 And David came to Saul and stood before him. And he loved him greatly and he became his armor bearer. 22 And Saul sent to Jesse, saying, I beseech you, let David stand before me, for he has found favor in my sight.
23 And it happened, when the spirit from God was upon 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.
