1 Samuel 17:55-57

New Revised Standard Version, Anglicised Catholic Edition

⁵⁵ When Saul saw David go out against the Philistine, he said to Abner, the commander of the army, ‘Abner, whose son is this young man?’ Abner said, ‘As your soul lives, O king, I do not know.’ ⁵⁶ The king said, ‘Inquire whose son the stripling is.’ ⁵⁷ On David’s return from killing the Philistine, Abner took him and brought him before Saul, with the head of the Philistine in his hand.
