1 Samuel 16:19-23

19So Saul sent messengers to Jesse to say, “Send me your son David, the shepherd.”

20Jesse responded by sending David to Saul, along with a young goat, a donkey loaded with bread, and a wineskin full of wine.

21So David went to Saul and began serving him. Saul loved David very much, and David became his armor bearer.

22Then Saul sent word to Jesse asking, “Please let David remain in my service, for I am very pleased with him.”

23And whenever the tormenting spirit from God troubled Saul, David would play the harp. Then Saul would feel better, and the tormenting spirit would go away.
