1 Samuel 17:53-55

New International Version

⁵³ When the Israelites returned from chasing the Philistines, they plundered their camp.

⁵⁴ David took the Philistine’s head and brought it to Jerusalem; he put the Philistine’s weapons in his own tent.

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.”
