When Saul saw David go out to meet Goliath, Saul asked Abner, commander of the army, “Abner, who is that young man’s father?” Abner answered, “As surely as you live, my king, I don’t know.”
But I will give you a way to prove you are telling the truth. As surely as the king lives, you will not leave this place until your youngest brother comes here.
So Jesse sent and had his youngest son brought in. He was a fine boy, tanned, and handsome. The Lord said to Samuel, “Go, appoint him, because he is the one.”
Then David went to the place where Saul had camped. He saw where Saul and Abner son of Ner, the commander of Saul’s army, were sleeping. Saul was sleeping in the middle of the camp with all the army around him.
