1 Samuel 16:14-23

But the LORD’s Spirit had left Saul, and an evil spirit from the LORD troubled him. Saul’s servants said to him, “See, an evil spirit from God is troubling you. Give us the command to look for someone who can play the harp. When the evil spirit from God troubles you, he will play, and you will feel better.” So Saul said to his servants, “Find someone who can play well and bring him to me.” One of the servants said, “I have seen a son of Jesse of Bethlehem play the harp. He is brave and courageous. He is a good speaker and handsome, and the LORD is with him.” Then Saul sent messengers to Jesse, saying, “Send me your son David, who is with the sheep.” So Jesse loaded a donkey with bread, a leather bag full of wine, and a young goat, and he sent them with his son David to Saul. When David came to Saul, he began to serve him. Saul liked David and made him the officer who carried his armor. Saul sent a message to Jesse, saying, “Let David stay and serve me because I like him.” When the evil spirit from God troubled Saul, David would take his harp and play. Then the evil spirit would leave him, and Saul would feel better.
