19 So Saul sent messengers to Jesse to say, "Send me your son David, the one who keeps the sheep."
20 Jesse then took a donkey and loaded it with a homer of bread, a jar of wine, and a young goat, and he sent it along with his son David to Saul.
21 That is how David came to Saul and entered his service. Saul liked David very much, and David became his armor-bearer.
22 Saul sent a message to Jesse: "Please allow David to remain in my service because I am pleased with him."
23 Whenever the evil spirit from God affected Saul, David would take the lyre and play it. Then Saul would relax and feel better, and the evil spirit would leave him alone.
