1 Samuel 17:55-57

New Century Version

⁵⁵ 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.”

⁵⁶ The king said, “Find out whose son he is.”

⁵⁷ When David came back from killing Goliath, Abner brought him to Saul. David was still holding Goliath’s head.
