1 Samuel 17:52-56 New International Version Anglicized (NIVUK)

52. Then the men of Israel and Judah surged forward with a shout and pursued the Philistines to the entrance of Gath and to the gates of Ekron. Their dead were strewn along the Shaaraim road to Gath and Ekron.

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 going out to meet the Philistine, he said to Abner, commander of the army, ‘Abner, 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.’
