1 Samuel 16:17-23

17And Saul commanded his servants, “Find me someone who plays well, and bring him to me.”

18One of the servants answered, “I have seen a son of Jesse of Bethlehem who knows how to play the harp. He is a mighty man of valor, a warrior, eloquent and handsome, and the LORD is with him.”

19So Saul sent messengers to Jesse and said, “Send me your son David, who is with the sheep.”

20And Jesse took a donkey loaded with bread, a skin of wine, and one young goat and sent them to Saul with his son David. 21When David came to Saul and entered his service, Saul loved him very much, and David became his armor-bearer.

22Then Saul sent word to Jesse, saying, “Let David remain in my service, for I am pleased with him.” 23And whenever the spirit from God came upon Saul, David would pick up his harp and play. Then Saul would find relief and feel better, and the spirit of distress would depart from him.
