1Sam 16:18-23

18One of the young men answered, “I have seen a son of Jesse the Bethlehemite who is skillful in playing, a man of valor, a warrior, prudent in speech, and a man of good presence; and the Lord is with him.”19So Saul sent messengers to Jesse, and said, “Send me your son David who is with the sheep.”20Jesse took a donkey loaded with bread, a skin of wine, and a kid, and sent them by his son David to Saul.21And David came to Saul, and entered his service. Saul loved him greatly, and he became his armor-bearer.22Saul sent to Jesse, saying, “Let David remain in my service, for he has found favor in my sight.”23And whenever the evil spirit from God came upon Saul, David took the lyre and played it with his hand, and Saul would be relieved and feel better, and the evil spirit would depart from him.
