1 Samuel 16:18-21

Then one of the young men said, “Behold, I have seen a son of Jesse the Bethlehemite who is a skillful musician, a mighty man of valor, a warrior, one prudent in speech, and a handsome man; and the LORD is with him.” So Saul sent messengers to Jesse and said, “Send me your son David who is with the flock.” Jesse took a donkey loaded with bread and a jug of wine and a young goat, and sent them to Saul by David his son. Then David came to Saul and attended him; and Saul loved him greatly, and he became his armor bearer.
