1 Samuel 17:55-57

New International Version

⁵⁵ As Saul watched David^(A) going out to meet the Philistine, he said to Abner, commander of the army, “Abner,^(B) whose son is that young man?”

Abner replied, “As surely as you live, Your Majesty, I don’t know.”

⁵⁶ The king said, “Find out whose son this young man is.”

⁵⁷ As soon as David returned from killing the Philistine, Abner took him and brought him before Saul, with David still holding the Philistine’s head.
