So the king said, “Then, find out whose son this young man is.”
Then Saul said to David, “You can’t go fight this Philistine—for you’re just a youth, and he’s been a warrior since his youth.”
Now when Saul saw David going out against the Philistine, he asked Abner, the commander of the army, “Abner, whose son is this boy?” Abner said, “As your soul lives, your majesty, I don’t know.”
So when David returned from killing the Philistine, Abner took him and brought him before Saul with the head of the Philistine in his hand.
