1 Samuel 16:17-23

16:17 So Saul said to his servants, “Find me a man who plays well and bring him to me.” 16:18 One of his attendants replied, “I have seen a son of Jesse in Bethlehem who knows how to play the lyre. He is a brave warrior and is articulate and handsome, for the Lord is with him.”

16:19 So Saul sent messengers to Jesse and said, “Send me your son David, who is out with the sheep. 16:20 So Jesse took a donkey loaded with bread, a container of wine, and a young goat and sent them to Saul with his son David. 16:21 David came to Saul and stood before him. Saul liked him a great deal, and he became his armor bearer. 16:22 Then Saul sent word to Jesse saying, “Let David be my servant, for I really like him.”

16:23 So whenever the spirit from God would come upon Saul, David would take his lyre and play it. This would bring relief to Saul and make him feel better. Then the evil spirit would leave him alone.
