⁵⁵ When Saul saw David go forth against the Philistine, he said to Abner, the commander of the army, “Abner, whose son is this youth?” And Abner said, “As your soul lives, O king, I cannot tell.” ⁵⁶ And the king said, “Inquire whose son the stripling is.” ⁵⁷ And as David returned from the slaughter of the Philistine, Abner took him, and brought him before Saul with the head of the Philistine in his hand.
