1 Samuel 16:18-21

One of the young men said, “Behold, I have seen a son of Jesse the Bethlehemite who is a skillful musician, a brave and competent man, a warrior, discerning (prudent, eloquent) in speech, and a handsome man; and the LORD is with him.” So Saul sent messengers to Jesse and said, “Send me David your son, 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 with David his son. Then David came to Saul and attended him. Saul loved him greatly and [later] David became his armor bearer.
