1 Samuel 16:18

Son of Jesse. Apparently David’s reputation as a musician and a man of bravery, sound judgment, and tact was already established before his appearance at court and his victory over Goliath. David was probably a youth on the verge of manhood, for a little later, at the time of his encounter with Goliath, he is described both as a “boy,” Heb. na‘ar (“young man,” ch. 17:58), and as a “young man,” Heb. ‘elem (“stripling,” v. 56).

Lord is with him. Though it was not generally known that David had been anointed king, nothing could hide the fact that the Holy Spirit, who had taken control of his life in a special way at the time of his anointing (see on v. 13), was successfully preparing him for the important tasks that lay ahead.
