51 Therefore David ran and stood over the Philistine, took his sword and drew it out of its sheath and killed him, and cut off his head with it. And when the Philistines saw that their champion was dead, they fled.
52 Now the men of Israel and Judah arose and shouted, and pursued the Philistines as far as the entrance of the valley and to the gates of Ekron. And the wounded of the Philistines fell along the road to Shaaraim, even as far as Gath and Ekron.
53 Then the children of Israel returned from chasing the Philistines, and they plundered their tents.
54 And David took the head of the Philistine and brought it to Jerusalem, but he put his armor in his tent.
55 When Saul saw David going out against the Philistine, he said to Abner, the commander of the army, "Abner, whose son is this youth?" And Abner said, "As your soul lives, O king, I do not know."
56 So the king said, "Inquire whose son this young man is."
57 Then, as David returned from the slaughter of the Philistine, Abner took him and brought him before Saul with the head of the Philistine in his hand.
58 And Saul said to him, "Whose son are you, young man?" So David answered, "I am the son of your servant Jesse the Bethlehemite."
